I now have a 75 gallon that is starting to come together. Finally i need to purchase a filter. It will be housing 4 goldfish. So keep that in mind. Id like to order it by tonight so that would be great. Thank you! Your input and experience is greatly appreciated.
You need a canister, preferably a big one like the Fluval FX5 or 6. Otherwise you'd need to do 2 Fluval 406 canisters. That's what I run on my 55g goldie tanks.
