Hi! I've just tested my water for Nitrates and got 150ppm! I was posting a thread about my SPS loosing tissue, couldn't find the problem until now.
I have 72G with 24G sump, 2x150W/20K MH lights, skimmer, 2 Koralia pumps, canister filter for phosphate removing media (clean every week)
What do I do now to lower the Nitrates? I did 20% water change yesterday (every 2 weeks) using RO/DI water and Instant Ocean salt mix.
Alk 1.7
PH 8.2
Nitrite 0
Nitrate 150ppm
Ammonia 0.25 ppm
Salinity 1.025
