Feel like I'm chasing my tail....
I have four tanks that have varying levels of light, pressurized CO2, and dosing ferts (EI). All four are pretty heavily planted. I have been trying to get my CO2 right, but even with all the reading I have done on here, I still don't know if I am there. I use a drop checker on all of them.
All read kh4-5, gh 3-4. I do 60% water changes and when I replace my water it is a 50/50 RODI/tap (well water) mixture. I regularly add either Seachem's Equilibrium or the GH booster offered on GLA's website to the RO water. I also dose a little extra Calcium for inverts. I believe I am doing okay with dosing ferts and by and large most of the plants that I have are doing very well and algae hasn't been a huge problem as of late and really only occurs on the tank I have the highest light.
So this week, 3 of my drop checkers have just turned yellow and not sure if I should adjust down or not, when the setting has been this way for nearly a month but it didn't turn yellow before. I reload my drop checkers at every water change. I have read to keep pushing CO2 up until your fish start showing ill signs and back off a little, but ill-effects can take days to kill a fish...I've done it. I don't like that approach for that reason. Is there another way?
What is the process of getting CO2 right? If there is another thread that outlines the process, please post a link. If I need to post tank specifics, let me know.
