I am newbie here...HI everyone.
Yesterday I tested my water and ALK very low (0.46) i added 19lb baking soda now my alk is 0.95 But the problem is PH is 8.6 today. My question is how do i low my ph without lower alk? i am thinking add some acid but this we lower both PHP and ALK. any suggestion?
Another question are how do i raise alk with out increase ph? or how do i increase ph without increase alk?
