Long story short. 90 gal
. Reef not drilled
Have had a nitrate problem which is due to the under cabinet filter I have, so went to lfs
& they have a gravity fed overflow box for the back of the tank that runs down to the 3 chamber box. I was told to put my protein skimmer & heater in there, sand & lr
in the middle chamber,& return pump in the third.
1) if its gravity fed, what happens during a power outage a flood if I'm not there?
2)the box is total 20 gal
. How deep should the sand bed be?
3) what other maintenance is there besides cleaning the "sock"? Do you have to scrub the rock after so long?
4) the tank is 6 months old. Would the ref have to "cycle" since it would be new sand & rock?
Thanks in advance
