question about JBL co2 test
If someone uses this test, can you tell if you are satisfied.
I brought the test kit for planted tank and inside is also the instant co2 test. I did three tests of this, with three different PH measures, 6.6 and 6.8 and 6.0 (all with my PH controller). My KH was the same 3.5. Unexpectedly I found and the three times what the chart provided says.
16 for 6.8, 24 for 6.6 and 104 for 6.0
Everything until here sounds perfect but if this is true, now in my tank I have a PH drop from 6.6 to 6.0 from injected co2 and KH 3.5. So is it possible to have 104 ppm co2 and my fish to be ok?
