i recently purchased a 150 gallon tall aquarium with a stand filtration and decorations all included for $400. i hooked everything up and my tank is up and running with 9 south american cichlids. have 2 emporer 400s with bio wheels running now and was wondering if that was enough? the setup also came with a undergravel filter and a canister filter (rena filstar xp4) that i didnt hook up seeing as how im not too familiar with canister filters. do i need more or am i alright?
