im setting up a 25 gallon saltwater fish only tank. i want to use a canister filter. i understand that ppl say it doesn't have enough biological filtration in it. sence all 3 stages r needed, can i run just a canister filter with 3 stage filtration that supports a much bigger tank to run it. therefore it will have alot of biological filtration for that smaller tank. im not gonna have any live rock, just fake stuff. ill have live sand tho. will i be ok? if not what do i need to do?
