I am a stay @ home mom & wife that loves her life!!! I am blessed in many ways except with the pool chemicals!! I am an owner of a 25k gallon, vinyl pool that with a sand filter!! Super easy, no brainer filer system, however, I fight the chemicals & algae all the time!! I am on well water w/out a softener!! We do have 1 dog that takes a daily lap in the pool but that is truly the only one that utilizes it!!! My test kit is a 3way & only test pH, Chlorine & Bromine!! The chlorine & ph are both off the chart!! I am think about using muratic acid to lower ph because I already tried the granular pH Minus with no results. I do have a small amount of algae that continues to show-up a couple of days lafter brushing it!!! Any help u can offer is greatly appreciated!! Thank you for your time & have a blessed day!!
