I'm just curious, In my 150, Iv'e set my ph control below 6.5 and c02 runs almost constantly.
At what point does the ph stop dropping?
I have no disturbance on top of the water, a power head is mid/upper level of tank.
There is a skimmer and two cansister filters moving water, thats about it.
There are two pieces of bog wood and medium plants growing.
Substrate : Black florite / eco-complete
Ph bubble is green
Kno3, K2so4, Kh2po4 and trace csm+b, dosed every other day , along with Excel
If I were to allow the c02 to run continuously would it lower? In not, then why? without adding buffers to lower it.
I'm not attempting to lower past 6.5, just curious, for a piece of mind as to why it stays the same , and if the ferts affect the ph in any way.
Just trying to educate myself
