Sister moved to new house with 9000 gallon IG fiberglass pool, sand filter, SWG. Attempting to start them off using TFP method. They were having trouble holding FC in pool with SWG, started SLAM yesterday. Turned off SWG, using liquid chlorine for SLAM. Numbers this morning: FC: 13 pH: 7.4 TA...

Suspicious of a leak, seem to be adding more water than usual. Tried the bucket test for 24 hours, results in photos. Air temp high 80s, water temp low 80s. Do these results indicate a leak,

Have a vinyl liner that looks to have been installed sometime in 2016, based on documentation provided by previous owner. Patter on liner seems to be slowly coming off in spots. Not sure what could be causing this? Any chemical imbalance that would do this? Chlorine level? Older Dolphin robot I use?

Hello! Opening our pool this year to a thick coating of leaf like green algae. This is my 3rd season opening the pool, haven't had algae like this before. When I brush the pool it stirs it up, and it almost looks like small green leaves floating in the water, but it is actually algae. It then...

Well, getting closer to pristine every hour! First time opening pool since following TFP methodology. After some guidance from a few forum gurus, started process 5/6/2020 in the AM, and 24 hours later have made huge strides already! Some dirt and cloudiness left to clear up, but the green is...

Removed mesh winter cover, and pool is very green and dirty! Could barely see to bottom in 3' shallow end, no chance of seeing the bottom in the deep end! Starting first SLAM process, checked pH first and got it in range. Want to confirm, I should stick with only chlorine and not use any...

I have a Hayward Perflex EC75 filter. When closing the pool yesterday and disassembling, I found the item in the photos inside the filter housing. I have no idea what it is or where it may have come from. Any ideas???

1st season owning a pool. Pool itself is ~25 years old, I believe the pool is on its third liner. I've noticed that the blue pattern on the liner, specifically in the deep end, is relatively easily scratched off. I first noticed it because I've used the leaf rake the most frequently in this...

Latest test results (tested myself): FC 1.5 (lots of swimming and sun today, bumping back up shortly!) PH 7.8 TA 110 CH 160 CYA 40 I’ve noticed some white flakes, but this evening there seemed to be a higher concentration of them floating in the water. Research seems to indicate that the...

I have a few teenagers who are swimming in our pool today after swimming in a pond earlier today. Advice I’ve received in the past (not here) instructed me to not allow suits in the pool post pond/lake swimming unless suits had been washed to avoid algae. However, the kids wanted to swim, so I...

The house we purchased in August has both a pool and 500 gallon indoor hot tub. I’m just getting acclimated to the TFPC method with the pool (working great so far!) so I’m now going to venture into tackling the indoor hot tub. Not sure what cleaning process was used previously, so I’ve purchased...

First time owning a pool at the beginning of the season! Previous owner left the routine they used during the season: 1) floating baskets with Trichlor tabs to keep chlorine level up 2) Shock once a week 3) 3 capfuls of Natural chemistry Metal Free once a week 4) 4 capfuls to Leslie’s Perfect...

Hello! I’m the proud new owner of a 30,000 gallon in-ground vinyl liner pool! We purchased the house towards the end of the season last year, and followed the previous owner’s advice on closing at the end of last season and opening at the beginning of this season- he was a diehard Leslie’s fan...
