@Dennis Wong @Yugang as the most likely contributers.. but anybody else with the info is most welcomed…

Is there a chart out there showing likely ppm co2 at different ph drops?

And correction for undetectable ph water? Ie under 1DKH?

Not a ph, kh co2 chart but specifically ph of tank sample and PH of a sample that is vigorously shaken and aired out for 3 minutes.

I have a 20 high I keep in the basement for quarantine, and keep it planted cause the fish definitely appear more relaxed around real vegetation..

When I have an extended period without fish in the tank the plants suffer. I am guessing because co2 levels fall off without livestock and fish waste decaying…

I am looking to supplement to around 5-7 ppm to keep the plants healthy and growing, but to keep trimming workload down and co2 costs down.
