Hi all. I replaced some tile in my pool and I'm wondering when I could raise the water level back up. I used a fast setting mortar that the manufacturer says could be used underwater and can be grouted within 2 hours and "traffic" in 4. Thanks for thoughts

Hi all, I had an old jandy cell with code 121. I ended up taking it off and cleaning it but it didn't work. So I bought a new one from an online supplier called pool supply unlimited. I just installed the new one. Initially, I had the same code again, 121. Then after about 5 minutes the code...

Hi all. I have 3 WFE 8, 2 HP Pentair pumps. They are old. They operate one water feature and 2 sets of jet returns. I have aqualink RS8. Original installation. If I purchased VS pumps, do I need to change anything with the Aqualink system? Also I found replacement motors online for good...

Hi all: I have an Aquapure 1400 cell. I am getting general fault 121 which means clean or replace cell. I seem to experience this when I open and when I close -- typically when water temp is colder. Right now it is 54 degrees and in October when I close, it gets down to the mid-60s. Seems...

Hello community. I have a couple of spots where my pool cover butts up against my pool edge but there are slight gaps where leaves in debris can get in. Anyone have good recommendations or links to products that would fill this void? Thank you.

Can you leave a plaster pool uncovered without water in it throughout the winter without it damaging the plaster? My plan is to replace the coping, tile and pool decking, along with reengineering plumbing, over the winter and I can't do that without leaving the pool empty. I did have a thought...

Hi all. Anyone ever add Calcium and the test doesn't budge? I added 12 lbs of Calcium to my pool which according to pool math should raise it about 46. I did this at a 250 reading. I tested a few times after and it was 275 once only to read 250 again. I added another 12 lbs and it went up to 275...

Hi all, I'm about to slam my pool. I'm going to lower the pH to 7.2. do I really need to wait 24 hours before I add liquid bleach? Thanks.

Hi everybody. I woke up to a green and cloudy pool this morning after flash flood type rain yesterday. I have been taking care of my pool for the past three summers and this has never happened. The last time this did happen was the first year I owned this house and I was not taking care of the...

Hi TFP community. I noticed some spots on my walls. Nothing obvious to the regular bystander, but I am very analytical with my pool. When I brush it, it comes right off. Later on, I notice that it comes back. From what I read, this could be a little mustard algea, although I also read that is...

Hi TFP community. How much does 1lb Cal Hypo increase CH a 30k gallon pool? Thx

Hey TFP, community. Hardness plus, sold at Leslie's is expensive. But I'm always hesitant to use products in my water outside of what's in pool stores. If I were to use the calcium pellets that I use in the winter to melt ice in front of my house, is that okay in my pool? Thank you.

Good morning TFP community. I am posting this question for a friend of mine who's having a lot of challenges with his Hayward 900, with a T cell Hayward 940. He keeps losing all of his chlorine throughout the day. He does get sun from set up to sundown. I explained to him that sometimes you have...

Hey trouble free pool community. I have this stubborn stain at the bottom of my pool. I slam my pool every open as I typically need to with the amount of algae I get. The pool is crystal clear and there are no stains anywhere with the exception of this one stain. I did a vitamin C test on it and...

High TPF community. I do not have DE blowing through my returns. But I do notice in the morning that there is a little bit of DE on the ground where the wall meets the floor and it's coming out of the skimmers. I assume this is blowback when the pumps turn off some of it's getting back through...

Hi TPF community. I have a slow leak coming out of my DE filter. It won't go away. I've tried all of the troubleshooting steps -- re-seating it, lubing the o-ring, hitting the clamp with a rubber mallet, Retightening without overtightening, etc. Filter is only a couple of years old. Should I...

Hi all...when you winterize a spill over gunite spa/pool, is it customary to leave water in the spa or is ok to leave it empty? Pic attached. I am in NYC area

Hi all: I have 2 skimmers. Both have 2 holes. In one of them the 2nd hole is capped off from underneath. In the other one, the 2nd hole is capped off with a winterization plug. My question is — is that winterization plug glued in and that pipe goes to main drain? If so is the main drain...

Hi all. There is a half inch pvc pipe coming out of the ground near my pump station that is capped off. What is that for?

Hi all, I was having an issue with my salt cell sensor giving me erroneous salt readings and eventually not detecting flow. After looking at troubleshooting guides I decided to purchase a new sensor. I installed it and it worked great for 10 days, reading the salt accurately and detecting flow...

Hello forum. Can someone recommend a good backwash hose? I bought one from Leslie's but it is poor quality, twists and gets jammed even after rolling it out straight. Thanks
