Hello all. wondering A way to pin down the cause of a high nitrate problem.
This is on going. Large water changes reduce it. but never to zero. I’ve tried multiple test kits to verify if it’s actually high or just old tests.
Tank is a 5 year running 90 gallon 1/4 cylinder with gyre wavemaker. Got a large piece of live rock don’t remember weight now. Sump is 25 gallon with a reef octopus 165, Refugio’s section has a 6x6 block of marine pure with chaeto usually growing above it. I have a 12 watt Full spectrum led grow light -Red 630nm and 660nm, Blue:460nm and White light 2700K above it. Aqua ultra violet 15 watt uv, and my return pump is a Tam Rio 2500. I only have a couple bubble tips, sailfin tang, and a foxface in the tank right now.
ph is at 8, alkalinity is at 9dkh, (bit low I think). Nitrates over 50, phosphates and ammonia 0. Nitrites 0.
oh yeah, and hair algae is constantly killing my Chaeto. but regardless of health of chaeto, or cleanliness, etc. nitrates are an issue.
