I'd go for a canister filter combined with lr
I favour my Eheim 2013 canister over lr
on my 32 gal
, its quiet (even less so than my ****ed air pumps!), and it keeps the water Crystal!
If i was running a larger 75 gal
, however, I would probably go for perhaps one canister filter combined with quite alot of lr
If you do decide to go for the canister filter approach go for an Eheim, mines beatifully reliable and I havn't heard great news about other makes.
