My 14 gallon set up has a very terrible brown algea problem. It only holds 3 neon tetras (the other two killed each other), my betta and 3 cory catfish. When I feed I do it in moderation so that there isn't a lot of waste. I plan on getting an otto, but I was wondering if there were any way to kill the algea quickly. I've just changed my fish tank filter, but that's not the problem. I always scrub my decor and clean it with REALLY hot water, but it's not working. Is there a super diluted bleach solution I could use to clean the decor or anything.
