hey there, getting close to getting a big canister, im looking at an FX5, rena XP3 or XP4. which do you think will get the job done and has the most bang for its buck over time?
setup is a 125g with an eheim 2217 and cascade 700, with (all juvies) an oscar, BP, 2 JDs, and 2 severums. so bio load will be moderate eventually. so i need an add on
all imput is appreciated
