Post septicemia Ryukin 5/14/13 Suddenly sick cichlid, iatrogenic 7/14/12 <Needs more room than this> 2 blood parrot cichlids, and one convict cichlid. PH is 7.8, Ammonia = 0, Nitrite = 0, Nitrate = 20+. <Keep under 20 ppm. See WWM re> Temperature is stable between 77 - 80. I noticed some algae growth around the white plastic parts of the Fluvia canister filtration system. The tank has been set up since about May and has been pretty stable, though the nitrates occasionally slip up to almost 40 where they were when I noticed the algae. I did a water change and left town two days later for a week. I used an automatic fish feeder while I was gone, set to feed twice per day. It is not the best process and the amount of food is not consistent, but I watched it for a week before and it seemed okay. When I got back, I had full on algae bloom. I still did not see a lot of algae growth on surfaces, but the water was very green. The fish were fine, healthy looking, swimming and visiting with us, and eating the pellets and bloodworms we offered. I tested the water and everything was the same with nitrates back up around 40, PH at 8.0 and everything else at 0. I did two partial water changes which helped lower the nitrates, but did nothing to minimize the algae bloom. Two days ago, I did a 50% water change and added Algaefix. <A mistake; toxic... PLEASE search ahead of writing us> Last night our convict got erratic and flapped crazily across the top of the tank. Then he returned to normal, but his feeding was off. Today, he won't eat at all. He has gone downhill all day. This morning he was mostly swimming normally, now he is laying on the bottom of the isolation tank we put him in. His color was normal, now seems a little light. We did not notice any unusual white, now he seems to be a little powdery or velvety. His breathing is getting more and more labored. We put him (might be a her, we don't know) in a separate tank and added Maracyn. <Of no use here> I've researched many things online and don't have a good resource locally that we know of. All that I've read has rendered me quite confused. Do I add salt or not? <.... see WWM...> Do I use Parasite Guard or not? Do cichlid pellets and flakes provide enough vegetable food or do I need to ensure the fish get more (when he starts eating if I am able to save him)? Thanks for your site and any help you can offer in this situation. Laura <You've written a good record of the causes of the troubles here. Too much NO3 (and likely other nutrients) due to... insufficient filtration, maintenance... Poisoning of the system w/ the algicide... Fix the environment here...

Questions. Always with the questions. FW Algae learning 4/25/08 I have a l55 gallon freshwater tank that's currently inhabited by 13 Neon Tetras and 3 Platies and a number of live plants. I know this isn't the best combination of fish, but I didn't realize that when I started out and bought the poor buggers. Eventually I'll separate the Neon's into a smaller plant less tank (with some Cory's too), but not until I've fixed the problems in the current one. By problems, I mainly mean a persistent algae bloom that I can "control" through frequent water changes and the heavy use of a diatom filter. Basically, I do a 30% to 40% water change, pop in the filter, leave it in for a few days and then take it out. A few days after that, when the algae bloom is really starting to gain ground again, I repeat the process. <Ahhh> I've taken the following actions to control the algae bloom. They all seem to work a little bit, but none of them by themselves or in concert vanquishes the green stuff. - Repeated dosing with Algaefix, an algaecide by API. <A poor idea...> This worked to an extent but never eradicated the bloom entirely. I can get better effect by using the diatom filter, so I've stopped with the Algaefix dosing entirely. <Good> - Restriction of the fish to an every other day feeding cycle, and being stingy with the food on the day they get fed. Poor fish, they always seem so hungry. The idea here was that if the cause of the bloom was from excess nutrients in the water coming in via excess feeding, restricting the amount of food provided would reduce the level of nutrients to a point where the bloom would go away. - Reduction of the amount of light to the bare minimum necessary to keep the plants from dying. Originally I had two 40W Aqua-Glo fluorescent bulbs. I found that if I dialed the timer back to where the bulbs were only on 8 hours a day, the bloom would grow slowly enough that I could go nearly an entire week before it got to a point where the diatom filter was needed. I subsequently replaced one of the aqua-glo's with a sun-Glo (4200K) which is not supposed to have the correct wavelengths of light to stimulate photosynthesis so that I could leave the lights on for longer than 8 hours. The algae bloom is a bit stronger now, but that could be because of the longer days now that we're heading towards summer. - Frequent monitoring of the level of ammonia, nitrates, pH, KH and GH. I know from my monitoring that the tank's *pH* is a rock solid 7.8 and that the *ammonia and nitrate* levels are pretty much zero as near as I can tell (thanks to the algae, likely). <All good...> So, with all this information, I've been able to narrow down the source of the algae bloom to one of three causes. (1) The artificial lighting. The thing is, I know that most people with planted tanks have much higher light intensities than what my tank has, so the artificial lights cannot, by themselves be the source of the problem. If that was the case, then everyone who had a planted tank with a higher intensity than mine would be having exactly the same problem that I am. (2) Light coming in from a nearby window. I knew it wasn't a great idea, but I installed my tank near a window. The thing is, the window is underneath a second story deck and never gets direct light except during the summer and even then only in the hours before sunset. Even then, there's never direct sunlight on the tank. There's a window shade that, while not opaque, does reduce the intensity of the light that does come in. So, it's entirely possible that the source of my problem is the light coming in from the window and the only solution is to move the tank. Boy, I really don't want to do that. (3) The third possibility is that there's too much phosphate in the water. I went out and bought a phosphate test kit and found that my tank water has a phosphate concentration of around 0.5 ppm. <This is high> I thought this was odd, as I hardly feed my fish at all and do frequent water changes. Besides, the algae does a great job of keeping the nitrate levels down near zero so why wouldn't it do the same with the phosphate? <Not a/the rate-limiting factor... is in excess relatively> In a flash of insight I thought to check my tapwater, and lo and behold it has a phosphate concentration of 0.5 ppm. <Ah, yes> So, I have a couple of courses of action and I wanted your advice on a couple of things. As I see it, I can move the tank to as far from a window as I can get it and I can buy some sort of system to get rid of the phosphate in the tapwater. <Is what I'd do, in addition to... boosting competition with the use of other photosynthates... plants> I'd prefer to do neither, but before I do either I want to know if one is contributing more to the problem than the other. So, here's my questions for you folks: (1) Is a phosphate concentration of 0.5 ppm by itself enough to cause a persistent algae bloom like I'm describing? <Mmm, along with other factors, yes> (2) There's this stuff out there called Phos-Zorb. The idea is that I can put it in a filter and use it to pull all the phosphates out of the water in the tank. If I then maintain the water level of the tank with distilled water for a while, I should be able to see whether removal of the phosphate alone takes care of the problem. Is doing this with the Phos-Zorb a good idea, or am I somehow going to kill my fish or something by using this stuff? <Better to go the longer-haul-fix of getting, using a blend of RO water... and for you to use the RO as well for your drinking, cooking purposes> (3) If removal of the Phos-Zorb takes care of the problem, what sort of RO/DI system do I need to get. <Mmm, just a "cheapy" from a large hardware store... learning to divert the "stored" water nightly to a container for water change use...> I gather that an RO system by itself doesn't remove Phosphates and that I need a specific resin to take care of phosphates, but I can't really tell from your FAQ's what specifically I want. Here in the NW we have extremely soft water. I have to add salt to the water I put in the tank to keep the Platies alive. Otherwise, they die quite quickly. <Mmm... I'd look into other means of raising the bar here... on alkalinity> Anyhow, thanks in advance for your advice. You guys were great when I was having problems (the soft water issue) with my platies a few months ago. Regards, Aaron Cooke <A bit more reading on the use of simple aquatic plants (perhaps just Ceratopteris floating... or Myriophyllum... the RO device, time going by, perhaps a bit more circulation, mechanical filtration (the addition of a large hang on or canister filter...) I wouldn't get into the chemical filtrant habit. Bob Fenner> Staghorn Algae, FW 3/3/07 Hello Crew: I've searched your website but can't find any information specific to "staghorn algae". Is there another name for this? <I have seen references to Compsopogon sp. being a possible name. I'm not really sure though, as my last search led me to an article about marine algae> I am encountering considerable trouble with excessive growth of staghorn algae. I have tried reducing the amount of light the tank receives and have cut the light time to 10 hours per day. I have tried using Algumin from Tetra (active ingredient: Simazine) <I am not familiar with this. Some sort of algicide perhaps?> <<Yes... and toxic... the principal ingredient in a few pet-fish and pond algae "remedies". RMF>> to no effect. I have tried frequent water changes and removal by hand as well as removing infested plant leaves. <Removing the leaves is one suggested course of action> I do not seem to be having an impact and it is getting worse and starting to grow everywhere. The tank has two Plecostomus and 4 Otocinclus, but they don't seem to be eating it. The aquarium does not get exposure to direct sunlight. <I have heard that rosy barbs (Barbus conchonius) will do the trick here, but I cannot verify that.> Water parameters are: ammonia: 0 ppm nitrite: 0 ppm nitrate: 25 ppm pH: 7.5 I am running out of ideas to try and combat this problem. Is there any other course of action I can take to reduce the growth of this particular type of algae? The tank lighting consists of two 18W florescent bulbs. One has a 10,000 K spectrum (Sylvania AquaStar) and the other is a special grow-light (Sylvania Gro lux) with spectral peaks at about 400, 420, 550, 600 and 650 nm. <What you have here is a nutrient imbalance that is favoring the algae. Try increasing the level of chelated iron, free nitrogen, phosphate, potash, and dissolved C02 in the water. Also your lighting is way less than optimal for plants. Even if you had a 10 gallon tank you would be just scratching the surface. A general rule of thumb is 2-4 watts per gallon. Or 30 watts per square foot of surface area. Obviously this is going to be higher if the water is dark due to dissolved tannins, perhaps lower depending on the species of plant, much higher if you have swords. Try increasing the water flow in the tank with a small powerhead or two.

Leave me in the bedroom!> ...any way LS is having problems, first of all DR had an algae problem because my husband kept opening the patio blinds in the mornings. Then I got some algae fix... <Yikes, dangerous... toxic> ...and we did a 50% water change, but I used some of the water to start the LS before the algae problem became apparent. So now the LS is cloudy as all get out and I do not know what else to do. I have done a 50 % water change, I have tried algae fix as well as tank cleaner where it gets all the organic stuff to clump together. <Counterproductive... Please read: http://www.wetwebmedia.com/FWSubWebIndex/fwalgcontrol.htm and the related files above...> So far no go. In the tank I have 2 blue Haps 2 Yellow cichlids, 4 barbs, 1 Betta, 2 Balas, 2 snails, and my pride and joy Freshwater white cheeked Moray. His name is Hang Loose. <Quite a mix... you realize the Moray is not really freshwater? Please read: http://www.wetwebmedia.com/FWSubWebIndex/fwmorayeels.htm and the...> I love him to death. I am somewhat of an invalid and when I wake up in the morning he is right there by my side. He eats ghost shrimp, brine shrimp, and a little mussel as I can see it. Can I make the water brackish? <Now with the other animals you list... the world is vast, animals of environmental condition ranges that do not overlap...> If so how? Will it hurt the other fish? How can I get the water unclouded???? Thank you for your advice. |
