Thank you, looks like a great read, although right off the bat someone is saying to not use a drop checker which nobody else online says to do
Hehe. Drop checker is not the best indicator. I do have one in my tank though for a quick glance. PH drop and KH levels supposedly have the best indication to CO2 levels. Anyway it's a lot of science I'm not too sure of
. Hoping this has helped you in some way.
