2 part solution dosing: Needs more ALK than CA


New member
I've been noticing that if I dose in equal parts of Randy's 2 part solution ALK and CA that the CA is always a lot higher than the ALK. It seems that as though my tank requires much as ALK than it does CA. Am I doing something wrong as I read that I should always dose in equal parts?

If the solutions were mixed up properly, generally, the same volume should be dosed. Most tanks eventually drift a bit, and dosing just one part or unequal amounts is fine if the measurements indicate it's needed.

Yeah, I have been dosing for about 6months now... Bert is right.. (He always is)

But anyway, I am dosing more ALK than CAL also. About 1/3 more on a daily average. Don't worry about it. It happens....
