So, I'm in Arizona and we have generally hard water. Now I took this into sons ideation, but when I just got my API tester, those results were frightening! Ph and nitrates also high...
Gh- 14 drops (chart only goes to 12 which is 214.8)
Nitrate- 40 ppm
Others are at 0, well ammonia might be .25
30 gallon(undergoing ich treatment):
Kh- 13 drops
Gh- 19 drops!!!!!!!
Nitrate- 80 ppm
Although last test I may have mixed up whichever tank is at what nitrate.
I am surprised how anything is alive... That oh is bad too, I even have driftwood in both tanks. The 20 has a sponge filter and the 30 usually has 2 carbon hob's running but currently it's floss for the ich treatment. Nothing has died in he 20 in a long time (maybe plants) in the 30 a few things died, I think from ich or treatment. Like my bs pleco and some cherry barbs.
