First off I want to say I own a pool business so have multiple pools with this problem because I neglected then based on my uncles training. Decided that I wanted to really learn about the chemistry and be an expert to give my customers great service. I've been trying since december to get my pools balanced with only a bit of improvement. Alkalinities were around 10ppm and ph's were around 8+. Now I have them around 50ppm alk, and 8.0 ph. But with the amount of chemicals I added to all these pools, and the fact that its the beginning of march, it seems to me that the method of getting these chemicals in are effective, but by very little.
As the subject says I have a problem with ph, low alkalinity. I just got advice today from my pool warehouse I should use sulfuric acid to drop the ph because it doesn't effect alkalinity, is this true? If not what do you recommend. I've been trying to add bi-carb and myruatic acid together, 2 scoops of bicarb(de scoops) and 1 gallon acid, its helping but not a lot. Is there a more effective way to deal with this particular problem? Is sulfric acid the best way to go? So then if sulfuric acid only effects ph, if this is true, I can add bicarb to raise the alkalinity to 100ppm and drop the ph to 7.4 with sulfuric acid? Is this right? I really need to find the best way to do this! Please help.
