In one of my tanks the Nitrate levels are around 10 ppm. The lady at the tropical fish store does not seem alarmed.
It is a 40 gallon tank with 5 Bluegill ranging from 3 to 5 inches long, plus 3 small Sculpin. Nitrites and Ammonia have been at zero for quite a while. I use an Aquaclear 110 filter with it.
I also have a 20 gallon tank with a single 4 inch Bluegill and 3 small Sculpin. Everything that is bad is at zero, including Nitrates.
Although I feed them pretty decently I have never had a problem with water quality, except for the usual 10 ppm Nitrate levels. I do weekly 25% water changes regularly and service the filter correctly. I feed them a lot because it is so much fun to do and they always eat everything.
Do I need to worry about these Nitrate levels?
