hair algae
Help!!
I have hair algae in my 55 gal planted tank. It's been up for 5 years, filled with crypts, swords, anubias, hygros, water sprite, and many others. I use 4 55 watt PC's 6400 K on for 12 hr.., CO2, 50 % monthly water changes, and weekly Fe/K supplements. I have 4 SAE and 6 Amano shrimps (anyone know of an online source for Amano's?). Fish are Rainbowfish. My other tank uses the exact same everything except for having tetras, and has NO algae......Any and all suggestions are appreciated. Dave |

I have hair algae in my 55 gal planted tank. It's been up for 5 years,
filled with crypts, swords, anubias, hygros, water sprite, and many others. I use 4 55 watt PC's 6400 K on for 12 hr.., That's 4 watts per gallon. That is a *lot* of light. You may always struggle with algae at that light level. Make sure you have a lot of fast-growing stem plants in the tank. With that light level, the tank needs to be full of plants, and most of them should be the fast-growing variety. I have 4 SAE and 6 Amano shrimps (anyone know of an online source for Amano's?). www.aquariumfish.net I bought my shrimp from them, and was very happy with the transaction. However, it might be cheaper to ask your LFS to order them for you. "Algae-eating shrimp" are usually on the stock lists these days. ..Any and all suggestions are appreciated. Post your parameters: KH, GH, pH, nitrate, temperature. And what fertilizers do you use? You say the tank's been set up for 5 years. Has it always had an algae problem? If not, have you changed anything recently? Leigh http://www.fortunecity.com/lavender/halloween/881/ |

Dave I don't know all of your parameters, but I had a recent outbreak as well. I tested and found my Fe levels were good to high, and my Nitrates were very low 4ppm. I had luck by adding just nitrates and holding off on the iron supplements. I've noticed Hair algae can be a bit light sensitive as well. I have two metal halide lamps, one of which fails to fire on occasion. When this happens the hair algae usually dies off, even if I light the lamp a couple hours later. So, as a first step, test your Nitrates to be sure they are high enough, with your lighting levels the plants will be consuming Nitrates rapidly. If they are low, bring that up and see if your situation improves. If that doesn't do it you can try cutting back on iron. I've seen no conclusive study on whether or not this is effective, but it seems to work for me. As a last step alter your lighting schedule (start 2-4 hrs later one day, end 2-4 hrs early on another). The fish may not enjoy this much, but I don't believe it will stress them that badly. Or you could use the full hammer and do a black out. Playing with lighting, especially a full black out, will probably work but won't address the real problem. I suspect it's a combination of light levels and fertilization balance. (Since you have so much light, you'll need a lot of fertilizer so the plants aren't limited). Hope something in all of that proves helpful! Rod |
