PH/KH/CO2 not adding up?
Yesterday before a %50 water change I had a PH of 7.4-7.6 and a KH of 17. This was after an hour of injecting CO2 into a 29g tank. Injecting slow as I'm using a new regulator and trying to make sure I don't go overboard.
Tank doesn't have many plants, EI dosing for 10-20g tank and running a 30" Planted+ on 24/7 mode.
Did the water change last night. Upped my bubble count just a tad and just checked my levels after its ran all day.
PH - 6.6
KH - 11
Putting CO2 around 82.9ppm????
I tried the tests twice.... API kits. Same results. I also have a drop checker in the tank thats a pretty deep green. Fish aren't freaking out or gasping.
Bad test kit??
