What is a CUC? And yes I have in total 3 powerheads but one is simply the eject of the hood filter shooting straight. I cannot/have not figured out how to angle the other 2 powerheads in order to circulate the tank. It always seems like there will be somewhere that does not get flow (hence where I noticed debris sitting there)
Also for my inhood filter, I do not think it is very good :/ it came with the tank (mistake for buying it) but yeah, I even actually cut the suction pipe so I could place it in the right spot but I think it was a mistake. I could just purchase another HOB
filter but I was wondering about canister filters, is it similar to HOB
in terms of it sucks the water from a single location or is it just a hose I shove in the water
LAST THING - Melosu58, it's okay to be vacumming live sand? no harm to bacteria/nitrate levels or anything else like that? Thanks!
