After a few bad experiences at my pool store, I am now purchasing my chemicals from Home Depot. It's close and they have everything I need, except for one thing: muriatic acid. However, they do have dry acid, which should work just fine. Now, just to make sure, I was wondering if there are any bad side effects to dry acid? I know chlorine in powder form messes with the CYA levels, so before using acid in powder form, I wanted to verify it is ok to use:
Active ingredient is sodium bisulfate (93.2%). What do you think? Safe for regular use?
Thanks so much!
