I have 20 gallon tank and have run almost 8 months. My tank have Welso, acan, chalice, favia, some mushroom and 6 frag SPS, 3 of those are acro. My coral pretty healthy last few weeks. However, they start to suffer, SPS don't extend too much polyps, some lose color, welso retrated almost a week. My parameter are below
Kh: 7.9
Nitrate: 4-6
Phosphate : 0 ( just check by HANAH UL)
Ph: 8.1-8.3
Cal: 430
Salinity: 1.025
Does anyone know how to raise phostphate up? Is it a reason why my coral suffer. I'm dosing NO3PO4 X to bring nitrate down. I dose 2 ml daily and running GFO.
