In-Ground 20,000 gallon vinyl liner chlorine pool with Sand Filter
This will be my 3rd season with pool and still having issues.
My pump went out sometime in the late winter and early spring so the water just sit stagnant. As the weather warmed up the algae set in and turned from light green to black.
I finally got the pump fixed last Thursday and with massive amounts of chlorine the water is now blue but still cloudy. I’ve ran the pump pretty much 24/7 and have been adjusting chemistries as I go. pH was initially less than 7 and is now 7.5. Total alkalinity was initially 0 and is now 140. Calcium was initially 50 and is now 150. I’ve been testing with a Taylor K2005 test kit. I took the water to the pool store yesterday and it tested zero on metals and dissolved solids.
Since running the filter and adjusting chemistries the water has remained cloudy and developed foam. Almost like a thin layer of shaving cream across the entire pool.
I added clarifier on 5/28 and ran the filter continuously for 2 days with no improvement.
On 5/30 I added flocculant and ran on recirculate for 2 hours and then turned off the filter overnight.
Yesterday morning there was a definite decrease in foam but not much improvement in cloudiness.
I replaced the sand in my filter yesterday and the filter didn’t run at all yesterday. The cloudiness was somewhat better today and I attempted to vacuum to waste but I could see some debris at the bottom but the water was still too cloudy to really see what I was doing.
I’m recirculating again and then going to turn off the filter and let it settle.
I’ve used flocculant in the past and the water was always crystal clear the next morning. Vacuuming to waste is a huge hassle but it’s worked in the past but only having troubles now.

Here at TFP we prefer to not rely on floc or clarifier products except in very rare scenarios. They don't kill algae and usually cause more problems later. To kill & remove algae, we emply the
