I have had my pool a couple of years now, but I am still concerned with what I think is excessive acid usage. Every 3-4 days I need to add between 400-800ml of muriatic acid.
My chems tonight are:
Total Alk 70
Cal Hardness 300
This is 4 days after I had the pool at 7.5pH, Chlorine at 10, Total alk at 80 with a cal hardness of 250 (I added some cal chloride to increase the hardness because the pool store kept giving me low readings) There has been no rain and I have lost about 1.25" due to evaporation, water temp 86-88 with ambient temps in the mid 90's
I had figured that by now I wouldn't need to add so much...your thoughts?
