Ha ha, I think we're going around in circles. So, yeah, the buffer increases KH and helps hold PH steady. If you don't have enough buffer in then it can drop. That is why you want to aI'm for 100ppm or higher. If you are heavily stocked or don't do enough water changes or large enough water changes then the buffer you have added can be used up which then the ph could fall.Leash said:Oh ok, I thought by adding the alkaline buffer to raise the KH, it would keep the ph stable so it won't drop?
Like I said, re-read my postLeash said:Ok so what uses up the carbonates?
