I am helping a friend with a neglected pool. This is to document the process and I am asking for others to "check behind me" since there are a few things that are different from my pool (which I have under control and have for over a year thank you TFP) such as this is vinyl, smaller, and pH is low which would be a gift to me.
This pool is a mess. There are frogs and baby frogs and it's pretty bad. I and the roommate scooped for about 3 hours. We started getting very little in scooping so I turned the pump to recirculate after "deep cleaning" the filter even though it didn't need it. Friend thought the sand might need attention but it was pretty clean. Put the filter back together and ran the pump on recirculate for 30ish minutes. Tested a sample and here's what we got. (This is on memory)
CYA 0 CYA is probable. The water is so murky that I am sure it is not an accurate test right now. We tried to filter it through a coffee filter but it didn't really work.
I was hoping to start the SLAM tonight but after a late visit to a local KMart they didn't have CYA and they didn't have Washing Soda and I didn't check for Borax. It was late and we were tired so I decided to cut off the pump for the evening and tackle pH in the morning and hopefully start slamming mid morning.
I am very tired so I am going to stop typing now. I will be back after it in the morning. First goal get pH into low 7s. PoolMath says 3.5ish gallons of 8.25 for 12FC (KMart has 10% for $5 which doesn't sound like a good deal to me) for target CYA 30 which I will get dissolving in a sock tomorrow morning. I will retest and adjust every hour. Friend will take over lunch-ish and I may come back Sunday later to evaluate. We have tons of bleach to start.
Thanks guys for any checks behind me and here are some pics. We will be crystal clear in days.
ps I thought of a question. Her sand filter is slightly different than mine. There a hole in the very top that is threaded and she says that when she backwashed briefly to test the new pump would allow a small bit of water out. I'm not sure if this should be plugged or is some sort of hydrostatic value should go there instead. Advice appreciated.
edit: I just read some Pool School. I will hit the local grocery stores for Borax to increase pH. I think PoolCalc had a smaller volume for washing soda which I why I was so fixated on it. Scooping for 3 hours in the summer sun does not make for right thinking and raising pH is foreign to me.
