Ok thats good. This is a 150 fowlr with a 40 gallon sump. The nitrates are always high as i have some messy eaters in the form of a chameleon wrasse and 2, soon to be three puffers. A narrow lined, a BSDF and a white spotted sharpnose.

High but stable is just fine IMM.
I just watch for consistent trends in either direction.
I may only act (more or less export) if not flat.
Coralline is a decent measure of overall tank health.
