My nitrates are reallyIt is the acs 10. It's on an 80 gallon display and probably around 12 gallon water volume sump (correct me if I'm wrong vintage), it has 3 clowns, 3 fire fish, 2 cardinals and two azure damsels. Clean up crew is 3 pithos,3 emeralds, 2 peppermints, two turbos, about 20 blue legs, and 10-20 nerites. Snails and hermits are locally caught, benefit of living in South Florida lol.
High (80+) on a 200g (160g display and 40g sump) I’m stocked heavy with fish. Run a skimmer and filter fleece. I wonder if the ACS 10 would be able to drive nitrates all the way down
