test results have changed:
I added what I had left of a calcium increaser.....probably a pound or two.
I also added about 4 oz of soda ash to bring the pH up a little, probably to around 7.6.
Really necessary to increase TA, or am I ok as long as I keep my CSI within range of no less than -.6 and .6?
Do I really need to bring CH up to 220?
