Our pool was just completed two weeks ago. We have dark gray, nearly black plaster in hopes it will draw the sun and warm the water slightly. We test the water daily and following the test kit guidelines we've added a pint of acid plus 8-10 pounds of Total Alkalinity every day. This is confusing and it seems like the chemicals would be working against each other. Does this sound normal? The gentleman who built our pool said because of our water we only need to be concerned with chlorine, acid and total alkalinity. Does that make sense? We both had pools as children but seem to have forgotten some things. We are reading pool school but hoped to get an answer yo this specific question right away.
