    Advice for pool with air leak on the intake side

    Hi colleagues. Thank you for all of the wonderful advice in the forums. I’ve learned a lot in the 4 years since we’ve had a pool at our new house. I’m looking for advice here: The pool is an unground acrylic pool of about 13,000 gallons. It has the original cartridge filter which I’ve been told...

    Oil / sludge residue on water line in skimmer

    Wildfires this year. That explains it for us. We’re getting some of the smoke from the Canadian wildfires here in Indiana.

    Pink Slime in Clorine pool w/ Frog

    Just about done with SLAM. Now I have a gray greasy substance in the skimmer. Still a sediment on the floor every day (it seems to get through my cartridges) but the water is clear and didn’t drop below 16 in 2 days. I still need to track how much it will drop before tomorrow evening as the CC...

    Pink Slime in Clorine pool w/ Frog

    Lol. No. I’m not comfortable swimming with pink slime, but since it’s really only in the filter and it is potentially resistant to chlorine (per the paper) I’m okay if a small amount survives the SLAM since it breaks down the CCs.

    Pink Slime in Clorine pool w/ Frog

    Interesting follow up on the pink slime bacteria. There is some reported resistance to chlorine, and except in a medical setting, it may actually be beneficial: “This is an important knowledge for drinking water industries which continuously search for cheap and effective ways to improve...

    Pink Slime in Clorine pool w/ Frog

    My pool math SLAM calculator says 11-16. Yes, I’ve read it. I haven’t SLAMd since this spring. I know how do that. Thanks!

    Pink Slime in Clorine pool w/ Frog

    I’ll go back and recheck all of the levels but they’ve all been stable except the chlorine. I didn’t replace the mineral cartridge in the frog this year, so it’s empty now, and I’ve just been using the frog packs so I didn’t have to add bleach more often. They’re all gone now too, so it’s...

    Pink Slime in Clorine pool w/ Frog

    So I’ve had this fine dark sediment for the last few weeks that settles out at night when the pool filter is running slow and the cover is on. I’ve also noticed some non-pink slime by the skimmer opening. A few weeks ago I added an anti fungal and the slime by the skimmer opening is less (I...

    Pump for DIY solar heater

    I just screw the end of my homemade solar heater into one of the eyeball ports from my filter and let it run filtered water through it and back into the pool.

    Cloudy Water

    So I closed my pool myself (following TFP guidance!) last fall and opened it myself this spring. I used a standard closing kit in the fall and didn’t use any special chemicals this spring other than slamming it. it’s been hard this spring to get the water to clear. It’s been cloudy and I...

    Getting a stuck attachment out of a return pipe

    The elbow piece is loose which is the biggest challenge. I may try breaking that part off and using the hacksaw trick. Has anyone ever used silicone pool lube (for the o-rings) before screwing something into the eyeball outlets? I’m now a little gun shy.

    Getting a stuck attachment out of a return pipe

    This is almost the identical piece I used. The ring on the right screws into the water outlet and the elbow pipe is loose. On of the small tabs broke off when I attempted to unscrew it, and with the Elbow pipe through the ring, its very hard to grasp the ring to twist or break it. I’m fine with...

    Getting a stuck attachment out of a return pipe

    Hi all - dumb question here, but I’m at a loss and don’t want to break anything. I was trying to raise my pH after adding Muriatic acid and found a new fountain attachment that the previous owners had never used. I unscrewed the eyeball from one of my returns and screwed in this piece to connect...

    High alkalinity, low normal pH

    The 120 was with a dipstick - when my reagents first arrived they were missing the key one for TA. Now I understand why I should not trust the dipsticks. I haven’t checked the fill water. I’ll do that. I know the calcium is quite high (it’s quite hard). The reagents are new.

    High alkalinity, low normal pH

    Hi all - TFP has been a godsend. I was visiting my local L pool store several time a week and they kept telling me my water was fine, or advising various chemicals to dump in it, so I was running quite a bill. Liquid chlorine is a bit of a pain, but the TFP plan has my pool clean and sparkling...

    Lowered CYA it came right back up

    Interesting. I just had the same exact issue with the same missing bottle. (only I got the kit right from the start). Annoying.
