That tank hasn’t had any carbon dosing since late August I want to say. Give or a take a month on that time frame. When I was carbon dosing, the skimmer was on. The skimmer has been off since then. I am dumping reef roids and pellets into the tank to try and stop my no3/po4 dosing. The fuge has been reduced to an hour a day for about two months now.Are you running a skimmer on this tank? I assume so because you say carbon dosing, but I'm curious.
I wonder how much of a bacteria/viral load a skimmer would remove from the water column.
Two auto feeder dump roids and pellets in constantly in an effort to reduce nutrient dosing but it only put a small dent in it
