I set up this 10 g tank almost a year ago. It has 5 CPDs and 2 otos in it. The PH is 7.5-8, NO2 is 0 and NO3 is around 10 (ppm). I had a serious BGA problem for a time, that I finally researched and cured with erythromycin. Everything was peachy for a few weeks after that, but then multiple algaes started growing and now they're taking over. I do weekly water changes (about 20%) during which I vacuum the surface of the substrate. I feed sparingly. I fertilize with root tabs. My light is a 15w GE Aqua Rays that came with the hood when I got the tank. I'm not sure what the PAR is (no meter). I have crypts, java ferns, anubias petite, fissidens and dwarf sag. Any advice on what I might be doing wrong would be greatly appreciated; I'm not sure if I have too much light for my low light plants or if it's not enough...or if that's even the problem? I can post some pics later if it helps (gotta u/l them to photobucket first). Thanks
