I've been trying to get my pH down from 7.7 to 7.5. The calculator says for a 15K pool 10 oz of 31.45 percent Muriatic Acid should accomplish that. Over the last 5 days I've added 35 oz but it's only down to 7.6. Any ideas on what is happening?
Good catch, linen.linen said:I just noticed you have new plaster. My understanding is the first year of new plaster the ph will go up continuously and need to be adjusted often.
