It's some kind of black algae... I tried covering it with a sheet and keeping the light off for a week but that didn't make any differenceDuaneV said:Sand is easier in general, but if you have an algae problem you're probably lighting the tank too much.
Hello Betta...BettaKat said:
I don't have any- just a mystery snail. I haven't been able to find one that I like yet that I can get at a real fish store (theres only 1 near me besides petsmart/petco and I've had bad experiences with fish there). I'm too scared to get shrimp bc my tank has had a few ick issues in the past and I wouldn't want to kill the shrimp with the meds.FriarThomasIII said:
I've been doing 50% water changes every week for almost 2 months now without any improvement and on the food labels, neither of them say anything about phosphate. Would it say if it was in there? I only feed them once a day toooldsalt777 said:Hello Betta...
Gravel is fine for your tank. Algae is going to form on sand too. Besides, sand can compact in areas and create water chemistry problems. Plus, changing out bottom material is work and not really an answer to the algae problem. You just need to clean up the tank water. Tank problems are mostly water problems, because there's more water in the tank than anything. Gradually work up to the point you change out most of the water weekly and change the food you feed the fish to something with little or no phosphate and feed less often. Try more freeze dried and frozen foods for the fish. These steps will take a little time to work, but they'll help with the algae problem and aren't much work.

Sunlight never hits it (in the basement office without windows) and the tank lights are on for probably 12 hours a day- usually 9am-8/9pm or something like that.NavyChief20 said:In addition to oldsalt777 's recommendation you might consider cutting back on the time your light is on. How long on average per day is the light on? Is the tank in a location that sunlight hits it?
Would this work?Mick Frost said:If you go with sand, I recommend using Pool Filter Sand. It's soft enough for Pygmy Corys, it fluidizes well (for avoiding H2S issues), its cheap, and it changes color if Ammonia issues are in your near future.
For Nitrate/Phosphate control you can try using "pretty Algae" like water lettuce or Marimo moss balls, or true mosses. They're all nutrient hogs.
