ok. so lately my trachys and wellsos and acanthophyllias arent as puffy. I tested with the hannah as well as salifert kits, and I'm getting 0 nitrates. I currently run an algae scrubber, skimmer, uv, and phosphate reactor. what would be the safest way to raise my nitrates? oh, I feed LRS fish frenzy and reef frenzy, as well as NYOS pellets and TLF veggie flakes. my fish eat good!!
