we bought a house with pool this winter [never had a pool before]. I don't know how deep the deep end is, so I guesstimate the pool is approximately 33K gallons. We were told to pump the water off the pool cover. DH has been doing it all winter and we ended up with half empty pool [it turned out the cover had holes]. We filled the pool and went to pool store, bought Dolphin and scheduled pool opening and SWG installation. Since they're very busy, they could come only in 10 days.
When the pool guy arrived, the water had slight green tint, but he said the water is good. He turned the pump on, said everything is good - no leaks, put 4 tabs in chlorine feeder and half of blue scoop of DE to the skimmer [previous owners' leftovers] and said that's enough for now. He also said he can't install SWG because an electrician has to update something and we better ask the electrician to move timer from the house to the pool [because it's more convenient and everyone does it]
In a couple of days the pool turned into a swamp. We went to the pool store to test the water.
They prescribed: 4lbs of Green to Clean, 4lbs of Chlor Brite, wait 12 hours, 2lbs of Chlor Brite, wait 12 hours, 2lbs of Chlor Brite, wait 12 hours. Backwash the filter.
The water turned blue in a few hours, but was still cloudy... Then we [finally] noticed that chlorine feeder was turned off [still wondering why the pool guy didn't turn it on ]
I've been researching how to backwash the filter and realized that our filter pressure is not rising, which probably means it's not filtering anything... and we probably need to add more DE. I added 2 scoops this morning. The pressure started rising slowly... but pool water is still cloudy.
I found some [leftover] tests. TAC was 4 today.
I also added ascorbic acid to remove yellow stains... I know I'm not supposed to do it with chlorine ... anyway, pH is somewhere between 7.2 and 7.5 now.
The question is: what do we do now?
and how long those 4 tabs of chlorine will last? They were ProTeam 3" Pure Tabs.
Thank you! I truly appreciate your help!
