I have had gha since starting my 13.5 gallon evo in august. I scrubbed the rock before now adding it to my reefer 170. It’s all back now I scrub it weekly with a toothbrush to get off as much as possible. And I’ve been running phosguard in the sump.
My parameters
Ammonia:0
Nitrate:0 I think my Api kit sucks especially with nitrate because I have never gotten a reading higher than 0
Ph:7.9
Salinity:1.023
Phosphate:0
Calcium:440
Alk: 10dkh
All this was tested 02/27/24
I also turned my lights from 11 hours to 8 and reduced the whites
