I wanted to see what you all thought about my next steps in getting my water back in balance versus what the guy at the water treatment store told me. Here's some recent readings (based on the TF-100 test kit) and steps taken:
Date TC pH TA CYA CH Salt Water Condition Steps Taken
6/18 6.0 7.2 110 25 Clear n/a
* Had a pool party 6/20
6/21 1.5 7.2 100 20 Clear n/a
6/23 0 7.0 130 <20 160 Very cloudy Added 2 gallons of 6% bleach & 4 lbs CYA
6/24 3 7.2 140 35 130 Very Cloudy Added a gallon plus 20 oz Muriatic Acid (to bring down alkalinity) *It had been running double what it should be for weeks.
6/25 2 6.8 100 40 140 3200 Very Cloudy n/a
Took the water yesterday to the water treatment store to get salt tested. His other readings were similar to mine although the sheet on which he wrote the results has the guidelines for a chlorine pool. He told me to shock the pool and raise the pH.
Here's my take: Obviously the chlorine tanked because of the party. I added bleach but didn't add the concentrated kind like I had in the past because I was being cheap. Our CYA has been low all season (since mid-May). Our TA alkalinity has been at least double the range the entire season. I thought we should address the TA and so we added Muriatic acid. Now our pH is low (well it was a bit low before).
I was planning on adding 2 gallons of concentrated bleach and more CYA.
What are your opinions on my situation and what I should do next?
Thank you very much for your input.
