ph is around 7.4. Slowly bring it down.
Gh 0 - 60 mg/l
kh 0 - 20 mg/l.
Nitrates need to go up. Mine was 0 until I accidentally over fed my fish trying to feed a slow Cichlid fish. Went up to 40 then I had string algae. Can be supplied with KNO3 dry
ferts or Brightwell aquatics FlorinK
Don't understand the Gh and Kh readings. They are 0 or the last number?
From my experience it is best to not try to change the ph. Just get fish suited for it. Cichlids I found don't adapt to the high ph. Some fish do adapt to high ph.
