Welcome to our forum.
Is there a rough amount of baking soda per 100 gal of H2O to add to increase alkalinity a certain amount? My Alk is 40 (filled it 2 days ago, and it has not changed) and I have 390 gal of water.
anne, try this page on Doc's site.....there's a box to plug #s in....http://www.rhtubs.com/info/water.htm
Great minds think alike.......
My water comes out of the tap with a PH of 6.8 and a low alk. What happens for me is I raise the PH to the desired level (usually 7.6) and the alk follows along. I have looked at alk after adjusting PH and it's around 130.
