In the last few days my mom and I noticed that the water in my 15 gallon tank has a slight yellow-green cast. We noticed there is a lot of algae growing on the dividers and other areas. The brush we have only goes so far in getting it all off. We've been putting algae-killing liquid we got from Petsmart in it but it certainly isn't doing its job.
What else can I do? I have a snail in there that I am sure is eating some of it. What else would you guys recommend? I've wanted to get a 'sucker' fish, as they call them, but I don't know if they come in the tropical variety and I heard they can damage betta's fins.
So, I don't know what to do. Should I get more snails? Any treatment you recommend?
Thanks in advance.
