Issues with pH/KH/CO2
I have a 10 gallon. Just got KH and pH test kits and the numbers are confusing me.
My KH is low, like 1-2 degrees. My pH is like 7.6. This puts my CO2 really low, like 3 ppm. I have DIY CO2 with a ceramic diffuser. My plants, especially my HC is happy. But obviously somethings not working right with the diffuser.
I don't feel like the tiny bubbles from the diffuser are really getting into the water column. They seem to still just go straight to the top and burst. I'm gonna try aiming a small power head at it to move the bubbles around some and we'll see what happens.
I have a power filter. Is the surface agitation from the water return causing my problem?
Is the low KH not allowing the water to take up more CO2? Is this a common issue with the glass diffusers? Any help is appreciated.
