Hi all,
I'm new to TFP after having a frustrating time delegating water testing to a store and getting yellow algae. After reading TFP's articles and doing my own testing I realized my CYA was way to high (~120) and this was probably stopping my chlorine doing anything at all. Since following TFP I've done the following:
According to the article I only need to keep yellow-SLAM levels for 24 hours, but after that should I just maintain regular SLAM levels until the cloudiness goes? Is there any other causes of cloudiness I should be thinking about?
Thanks for your help.
pool details: 20,000 gallon, plaster, in-ground, sand filter (skimmer only, sand replaced Feb 2020)
I'm new to TFP after having a frustrating time delegating water testing to a store and getting yellow algae. After reading TFP's articles and doing my own testing I realized my CYA was way to high (~120) and this was probably stopping my chlorine doing anything at all. Since following TFP I've done the following:
- Drained the pool ~80%
- Refilled the pool
- Added Muriatic acid to lower ph to ~7.2
- Added liquid chlorine to quickly bring chlorine up to SLAM levels, checked levels every few hours to keep them steady
- Been steadily adding CYA to bring it up to a desired level (around 20 right now)
- Been doing daily runs of the pool robot + brushing etc, pump running 24 hours at 2350rpm
- Last night the pool passed the overnight chlorine test (stayed at 9ppm over night) and has less that 0.5ppm CC, so today I raised chlorine levels to the higher level for yellow algae posted here
According to the article I only need to keep yellow-SLAM levels for 24 hours, but after that should I just maintain regular SLAM levels until the cloudiness goes? Is there any other causes of cloudiness I should be thinking about?
