question...my ph is 6.1....and mydkh is 1...ppm gh/kh is 17.9...with out co2 injection?...my question is my tank getting co2 from elsewhere?

oOKkay...This way is much clearer:
dKH = 1
dGH = 17.9
pH = 6.1

It will help if you provide more info on plants, tank size, lights, trying DIY CO2? etc.

If lights are strong enough plants' chloroplasts are able to make plant sugar/energy from carbon in solution (depending on plant requirements this translates to having preferably higher alkanity).

Floating plants are able to get their energy from carbon dioxide in air but also benefit from carbon in solution as carbonates, organic soil, etc

How would you use this chart if your PH is past 8.2? Or better yet keeping your PH at 8.2 while maintaining adequate PH. I have hard water cichlids (lake Tanganyika), but am planning on planting the tank. Is there no way to keep the KH/GH at 8-15, PH at 8.1-8.3 and still maintain decent levels of CO2 with very little swings in chemistry?
