Heya guys and gals. Started using a scrubber on my newest build. Been up and running for about 6 months. I have only done 2 water changes and that during the cycle. I do, however, seem to have a problem. My nitrate and phosphate are running at 0 or close to 0. This is not optimal for many corals. Does anyone have a solution or tips . I have increased feeding to the point I am scared the fish will explode. I do not use a sock as I like my pods staying in the tank.
System:
90 gal DT 40 Gallon sump/fuge total water around 110 gallons after rock sand etc.
Avast CS2 skimmer 24 hour operation
10x12 waterfall scrubber light cycle 18 hours
Chaeto ball
had a Santa Monica HOG 3 but turned it off because the waterfall out-competed it and it did nothing but make bubbles
phosban reactor 24 hours
occasional carbon
2 part dosing
