overflow/sump vs canister filtration in LARGE heavy planted tank?
ok so i have a 265 gal tank with central overflow and it drains down to my 120gal sump that has a filter sock, filter mat then about 40gal worth of bioballs in middle.
as a mechanical, biological filtration, this setup hands down beats over 3 Best canister filters IMO. but i talked to some people and seems that the overflow can pose problems after trimming such as clogging etc.
am i worried for nothing?
should i just get 2 canisters and 2 hangon filters and not run my sump filtration?
this is gonna be lowtech tank so no Co2.
this used to be a REEF tank.
