No, This is not a weird topic. Sparkling clean tanks are desired by all aquarium owners. Your fish tank should be something you are proud to show. I suggest that you analyze your filtration system. My tank is about 1/3 the size of yours, but I have about 4 times more fish that you do.

I use use the AQUA ONE 1000 canister filter and a small sponge filter for my tank. I clean the canister one time a month, and I clean the sponge about once a week. This keeps my tank sparkling clean.
