Best filter setup for my setup and tank changeover advice Marine Filtration and Tank Changeover 11/17/08 Hi to all, Thanks to you all for your time and commitment to our hobby. <Thank you for noticing the commitment!> I have searched your site for info on my topic but was looking for an opinion on my exact setup. I currently have a 46 bow reef that is filtered by: 1 Aquaclear 110, 1 Remora skimmer, aprox 2/3 filled with live rock and 1 power head. This setup and run well (I think) with no issues for 3 years. Now I am changing out to a 72 bow non-RR. I am not sure on the best filtration for this setup. I want to stay away from the standard type of "open" overflow and wet/dry filter. Not sure why but, mostly because of noise and sump size. Although, I went with the non reef ready because I travel a bit for work and cannot always top off as frequently as a RR wet/dry small sump needs. (wife can feed fish ok but not up to topping off for me). <If you have the room for a sump, do reconsider. Auto top off units out nowadays are great, and very beneficial to tanks with or without sumps through the consistent SPG they keep.> I am thinking about a canister filter (please recommend best type/brand/model for my tank size if you can) <Eheim, first choice.> and another hang on mechanical filter, a tank 2/3 full of live rock and 2 power head for flow ....?? What do you think about this. Is there a better way to filter my setup? <Personally I would forgo all of the traditional filtration. Just rely on LR and the Remora...really.> What is ideal? <The above with a sump and refugium.> And last, what is your thoughts on a 2 day cutover from the 46 bow to the 72 reef? Steps: SAT AM -move half water and all corals and fish to Rubbermaid bin. -move light, Aquaclear 110, and heater to the coral bin for 24 hour stay. -move base rock to 2nd Rubbermaid bin. -remove remaining water sand and breakdown tank. -set new 72 bow and fill half way with new saltwater. -install sand and base rock. -fill all but 2" and get filter and heater working(no powerheads yet) SUN AM or PM as needed for water quality -hopefully most of the sand has settled and water is just cloudy -replace corals and fish Will this work OK? <It will, just keep the bins aerated and heated. This really can be done in one day, a few hours at most.> Should my fish and corals survive?(2 damsels, 1 Oscels. clown, 1 yellow watch men, mostly mushrooms, zoos, softies and LPS-no SPS-PC lights) <Yes.> Any additional advise on the change over? <Sounds like you have it. Just do it fast and keep your water the livestock is in as consistent as you can.> Thanks again for your time and all you guys and gals do for the hobby. <Thank you again, Scott V.> Reef Plumbing/Filtration -
04/09/06 Hello, <<Howdy>> I have just switched from a
55 gallon tank to a 90 gallon tank with a 30 gallon sump.
<<Cool!>> I have four 1-inch bulkheads in my tank and a
Mag-Drive 9.5 in my sump. The guy where I purchased this
tank from (Steve, from Elmer's Aquarium in Monroeville, PA) said
this would circulate 1000 GPH. <<Would be close, yes...assuming
no backpressure for the pump to work against. In reality
your flow will be somewhat lessened, determined in large part by your
plumbing configuration.>> One of my questions is that I only have
one bulkhead open because that is all the pump can handle.
<<Likely your plumbing/head height (all creates backpressure) are
severely restricting output.>> So this would be 250 gallons GPH,
correct? <<Mmm, not necessarily...but if the single 1"
return is handling the flow without excessive noise, surge, etc., then
you are likely pumping 350 gph or less.>> Is that enough
circulation that I can just leave it alone? <<Through the
sump?...yes...for the tank as a whole?...no. Do supplement
flow in the tank with other methods...perhaps a closed-loop utilizing
one or more of the other bulkheads.>> Only thing I noticed wrong
was one of my elbows coming out of the sump is dripping once about
every 1 to 2 minutes. And it is dripping back into the sump
tank so I am not really worried about it. <<Ah, okay.>> The
micro bubbles are very minimal. What am I doing wrong?
<<I don't know that you are (doing anything wrong)...I would
need more information about your plumbing configuration to say.>>
My next question is do I need to run a canister filter for this setup?
<<Likely the canister filter isn't 'necessary,' but
one could be beneficial for using chemical media
(carbon/Poly-Filter)...if 'maintained/serviced'
properly.>> I currently have about 50 lbs. of live rock, some
corals, 2 yellow tailed damsels, 1 yellow tang, 1 goby, 2 clown fish, 1
royal Gramma, 1 flame angel, 1 coral beauty, 1 cleaner shrimp along
with a cleanup crew. I have read on this site that canister
filters are often misused with tanks running a sump. <<And also
those without...is a maintenance (or neglect of) issue.>> Would a
canister filter help me or hurt me? <<If you clean/rinse all on a
weekly/bi-weekly basis, and change out media as it becomes exhausted,
then it will help you. Regards, EricR>> Confusion; Sumps, Refugiums, Wet/Dry Trickle Filters, Flow Rates, and Wavemakers -- 09/21/07 Dear Sirs, <<Greetings Carl...and BTW, very capable ladies here as well>> I love your site. <<We thank you>> I am still fairly new to this hobby and am pulling my hair out at the variety of information available. <<Mmm, yes...much info with varying opinions...but do keep reading/absorbing>> I have made some progress, but have recently decided to take a step forward and it just so happens that this next step seems exceedingly baffling. <<Indeed, many hobbyists are intimidated by the plumbing/flow/circulation aspects of tank setup...let's see if I can help with your understanding re>> Currently I have a 46-gallon bowfront with a wet/dry which returns via an Aquaclear 70 powerhead. I have ordered a refugium and plan on turning the wet/dry into a sump (I will then use both the sump and the refugium), but I really can't figure out the plumbing for this. <<Quite elementary really... The tank drains to the skimmer chamber of the sump...a T-fitting is installed on the drain line with a gate-valve on the output, and leading to the refugium...the refugium then 'gravity drains' to the pump chamber of the sump. Plumbing the vessels in this manner lets you adjust/maintain a different flow rate in the refugium if you wish>> In my setup, both the sump and 'fuge must be below the aquarium. <<Very common...and is how my system is configured. Depending on the height of the individual vessels, you may find you will need to elevate the refugium slightly to allow it to gravity drain to the sump>> Besides plumbing, I am also confused by flow rates. <<Okay>> I understand that the aquarium flow rate should be higher than that of the refugium, but how much exactly should I be aiming for...i.e. aquarium 8xhr? refugium 2xhr? <<Is variable...often dictated by the animals/species kept. But as a general starting point this would be fine...could even add a couple more 'volumes per hour' if you wish>> Is my Aquaclear 70 adequate? <<As a means for circulating water through the sump/refugium, maybe...depends on how much head-loss you experience with this pump...but is likely inadequate on its own re water movement within the display>> Wavemakers: I ordered a Wave2k before I read your opinion on them. Should I return it? <<Mmm, I've not used one of these devices...but I think it will overpower your 46g tank with both its size and performance. The Koralia or smaller Tunze Stream pumps would be a better choice here...in my opinion>> I was planning on keeping it and augmenting in tank water flow with a Koralia #1, a Koralia nano for bottom of the tank water movement, and the return from the Aquaclear 70 of course. <<Ah well...you don't need (or want!) the Wave2K then>> Thanks, Carl <<Here's some links to more useful info (http://www.wetwebmedia.com/plumbingmarart.htm ) and (http://www.wetwebmedia.com/circmarart.htm ) and (http://www.wetwebmedia.com/ca/volume_2/cav2i5/wavemakers/Wavemakers.htm ).

What Is The Best Filtration Sequence For A Reef Tank? -- 09/19/07 - Biological, chemical, mechanical. - Biological, mechanical, chemical. - Chemical, mechanical, biological. - Chemical, biological, mechanical. - Mechanical, chemical, biological. - Mechanical, biological, chemical. <<Mmm, well...biological filtration is going on most 'everywhere' in the system...but if setting up/arranging sequential filtration modules, it is my opinion the last sequence listed (mechanical, biological, chemical) is the best, for 'any' marine system. Mechanical filtration first (changed or cleaned frequently) to trap and remove detritus/organic material to reduce the load on the bio-filter (I consider a protein skimmer such a device)...biological filtration next, to process 'dissolved' organic compounds...and lastly, chemical filtration to augment these processes and help reduce toxic levels of those elements not handled by the previous two methods>> Thank you for your help. <<Happy to assist>> Your website is very informative. <<Hope you find it useful>> Sincerely, Tara Price <<Regards, Eric Russell>> Re: I am going crazy!!! (revised, I hope this is better!!)... Reef tank filtr. mainly 4/25/07 Hello Mr. Fenner and crew, <Jerry> After all the late night reading and studying, I find the more I read and learn, the crazier I feel I am getting. Here is my dilemma, I wish I can say I was one of the ones that studied first and purchased second, but I wasn't. Put that together with impatience and you have a disaster waiting to happen. I have a 75 gallon LR/LS reef tank, stocked with everything the LFS could sell me, (huge amounts of corals). I have a small 17 gallon wet dry (18"x10"x16") and a 405 Fluval (contains bios and Purigen). I have an Aqua C Urchin/Mag sitting in my sump and next to that is a Rio 1250 gph. The Rio returns directly into the left side of my tank. Since I was out of room in the sump, I put a Pondmaster 2400gph outside. The Pondmaster is pumping water to a JBJ chiller through a wall into the next room (it took weeks to convince my wife!!). This returns to the right side of my tank making a travel of 5' each way. I had perfect water for months and now it seems the water changes are not keeping up with the production of nitrates. <... You have read re Wet-Dries on WWM: http://www.wetwebmedia.com/bioballfaqs.htm and the linked files above?> I was past 240 and did a 30 gallon water change, and now it's down to 100. I plan on doing another big change in a couple of days. (yet my corals/fish seem fine?) I read from your site to remove bio-balls, I did that and replaced it with 4" of live sand and 16lb of broken live rock. I have also added 2 full bags of Chaetomorpha to the sump/refugium. I am still going through the drip plate and PolyPads dropping down on top of the Chaetomorpha and LR/LS. Is this okay? <Yes> I started to feel that this refugium is not enough (always my problem), it is currently 8"x10". I have read that any refugium is better than no refugium. <This is so> Now I have so much water in the sump/refugium that if I had a power outage, I would have about 5 gallons or more on the floor and a divorce!! <Trouble... need to reduce the amount of water in the tank/system...> Recently I bought a new tank 24"x12"x16" for a separate refugium. I would go bigger but I have space constraints. I have just recently read about this miracle mud. So now my brain takes me to another direction. Tank water through the drip plate/poly pads into the miracle mud compartment. Flow through to the skimmer side, Rio 1250 taking it through the wall 5' to the refugium. Pondmaster 2400 will take it from the refugium to the chiller (too much flow into chiller?) <No> and back another 5' to then split to both sides of the tank. Is this crazy or should I just keep it simple? <Simple is better... Do read re how much flow to send through/over the Mud... not much. Best to restrict flow or bypass through this compartment> Either keep things as they are and purchase a Sulphur Denitrator. Pull the sump/refugium out; replace it with the new tank/refugium and put it under the display and call it a day?? <I would do the latter> PLEASE HHEELLLPPP!! I don't want to hurt anything in my tank with my constant changes. Ps I have a red Caulerpa in my tank and it has grown large dark purple almost black grapes on them is this normal? <Possibly... better to remove this material if it starts to decompose. Bob Fenner> Jerry Re: Some questions about reefs: Filters Hi Bob, I setup a 2 foot tank under my display tank and everything is in the sump now, including heater, Eheim filter, UV light, skimmer and pump. I installed a hang-on type overflow. I switched off the power to the pump to see if the sump would overfill and it looks good. (Sounds good) I installed the Turboflotor 1000 multi and retired the SeaClone. I have a few questions about the Turboflotor. The model they gave me is for a 500-1000 liter tank. I only have about 350 liters. Will the skimmer be okay on my tank? (Yes... a much better choice) There are two adjuster valves which you can turn and this will adjust the height of the bubbles going into the collection cup. Sometimes some water leaks from them as the seal is not very tight. Is this a design fault or have I done something wrong? If I have, how do I fix it? (A little of both... do take the unit apart and put a swipe of silicone-grease like for camera O-rings on the seals... and raise the water level in the contact chamber to just under the collection cup...) I do have room to put a light over the sump and put substrate and live rock in there. I have read about this on the WWM site, but I just want the skimmer to kick in first and hopefully improve the water quality. You should have seen the salesman's face at my LFS when I brought a 2 foot tank instead of his special bio-ball (very small) tank. He was not happy. (Tough... you did the right thing) The corals are looking better today (I suspect the SeaClone was helping a bit). (Yes) The setup is very nice with the overflow and sump. I'm pleased that I did not have to have the tank modified to have an overflow and sump. If you want to have a look at what I have done, I can put some pictures up on the net, just let me know :) Warmest regards Lucien Cinc (In a few days... when I get back from Cabo-Baja-Mexico... the connections here are not rapido... Roberto Fenner) -Protein skimmer placement- I have a 220 gallon tank with an Amiracle 30 gallon sump. I have 2 overflow boxes that hang on the back of the tank. They say that you should use raw water to run in to the skimmer. <Would be nice, not the end of the world if this can't happen.> If my water is flowing into the sump via the overflow boxes then into my filter pad then bio balls how do I get raw water to my skimmer then get that water in to a filter pad? <I wouldn't worry about it, most tanks are set up that way.> I do understand the concept but most of the sumps that they sell are not set up that way. <In reef aquaria I don't recommend any type of mechanical filtration, so if you remove that stuff, you'll get the "raw" water you desire.> I will admit that when I purchased most of my stuff I had sucky advice. At that time I did not know about wet web media. Thank god I did learn about you guys (and girls?) though. <A few!> I know that the output of my skimmer will not keep up with the incoming water. What do I do? <Turn down the incoming water w/ a gate valve?> I do have an extra sump laying around could I use that somehow? It is smaller, like a 10 or 15 gallon sump. <Well, I suppose you could tie it in to this one but it would require lots of drilling for little to no gain.> I have searched here and the internet but have found nothing solid to go on. be feasible to eliminate the sump totally? <Not really, you need a sump for an adequately sized skimmer.> A friend was selling his tank and I bought it. He had over 300 pounds of live rock in his tank. Before that I had a little over 300 pounds in mine. So I have over 600 pounds of live rock in my tank. <Holy crap!> He had his tank setup for about 6 years and the only filtration he used was a skimmer. I am leery about using that set up since I have never done it before. <No worries, you could run the pacific ocean on 600lbs of live rock!> I have looked for a good site explaining the Berlin style but came up wanting more. Know of any good sites or books about it? <Why yes, check out Bob and Anthony's new book called Reef Invertebrates. See Wet Web's front page.> What do I do? I am leaving the survival and quality of my tank in your hands ( no pressure). Would it be ok to use 2 skimmers? <It would be much better to use two so that when one was cleaned, the other would assure that skimming is never interrupted.> I have a Berlin XL and a Turboflotor, yeah I know, they work though. <Pick up a Precision Marine bullet 3 or an AquaC EV-240 and I'll show you how a skimmer is SUPPOSED to work! I think you're in good shape for now, good luck! -Kevin> Talk to ya later. Kenny
