Hi guys,
I was wondering if someone could clarify the whole ph kh co2 mg/l relationship.
According to denerelle (sp) and their co2 chart my tank has 13mg/l co2, with the ph being 7 and the kh at 4.
Now really they recommend with the ph at 7 a kh of 6 to give me 20mg/l
or a ph of about 6.8 and a kh at 4 to give me 20mg/l
so I either raise the kh or lower the ph right? What's the best way to go, I could buffer the kh with bicarbonate of soda but wont this also raise the ph? The only other thing I can think of doing is increasing the co2 to lower the ph. Is this right??
