So I have a 37gal tank right now with three goldfish. Its a little small and I plan on upgrading to a 75gal in the future. I'm hoping to buy a canister filter sometime soon large enough for this tank and my future one. Anybody has any good suggestions? My tank has three filters on it right now. One that came with the tank, one brand new (as of about five minites ago) sunsun 40gal submersible filter and one 5gal filter. I am having a tough time with my nitrate levels recently and I ordered some filter media thats suppost to help with that although next time i'm ordering purigen. Also how do they work exactly?....I've never had one before.
