    90% water loss

    Hello. I probably need as new liner but just to confirm with the pool pros.. 35k gallon pool. Almost all the pool water is gone. Some water appeared in concrete basement. Liner is about 15 years old. Is it time for a new liner?

    Pump Primiing on and off

    Thanks, Ok. I'll need to raise the water level and return to using skimmers & main drain. There doesn't seem to be any debris but it's possible the MD is clogged. Pool needs to clear up more. There is no flex PVC in the plumbing.

    Pump Primiing on and off

    For the past 2 seasons, I had the skimmers turned off and using Main Drain only with no problems. Does using MD only cause a problem in the system? When I adjusted the Jandy valve earlier, the pump achieved full prime from about 80% prime (10-12 PSI) but then lost it and it has not recovered.

    Added DE to sand filter

    Thank you for your informative replies. I will pay more attention to the skimmers. I also have the valve at about 75% skimmers, I have two and 25% main drain. I deep cleaned the sand filter before opening this season. There may be more debris than usual because I didn't open the pool last year...

    Added DE to sand filter

    3 days ago, I added DE to the sand filter, per the instructions and the pressure increased 20% within 24 hours then I backwashed and rinsed. Yesterday, I added more DE and the pressure only increased about 10% but the skimmers were not skimming well. Lots of debris on the top of the pool. So I...

    Duck eggs near the pool

    Hi all. I have seen ducks come and go before by my pool in the spring only but today I found a nest with duck eggs. 2 ducks have been spotted in the morning every day. I left the nest undisturbed with about 8 eggs. Any suggestions?

    Deep cleaning sand filter, possible mistake?

    Update: The results of deep cleaning worked very well. I opened to a dark green pool because I did not open last season. The pool started turning blue after only 2 days. I can see the bottom of the shallow area. I took the advice from the experts here about opening earlier, when the water...

    Deep cleaning sand filter, possible mistake?

    :ROFLMAO: :ROFLMAO: Thanks for the great explanation. Doing the deep cleaning this way is way less messy and much easier by having a side mount filter because there is no removing the MPV. What if I had a top mount filter and did the deep cleaning this way? Any difference?

    Deep cleaning sand filter, possible mistake?

    Ok, when I covered the standpipe with my hand, the water was flowing out from the top. I made sure I removed as much debris as possible from the top of the sand before using the hose. Also, early in the process when the water reached almost to the top, there was foam and bubbles. More than in...

    Deep cleaning sand filter, possible mistake?

    Hi all. I deeip cleaned my sand filter today, as per the instructions. I made sure the filter was disconnected from the pipes leading into the pool. After about 10 minutes of gently moving the hose around in the filter, I realized that the filter was still connected to the waste port, so all...

    Should I open early in NY? Did not open last year.

    Thanks. I will check for availability of LC. I recently purchased a complete refill of k-2006 from TFteskits, so I'm good there. How about the foam and/or ammonia problem? If there is enough LC, should I remove water?

    Should I open early in NY? Did not open last year.

    Hi all, I have a few questions. Should I open early, about mid April? I'm guessing the pool water will still be green even with the cold temperature, due to not opening last year. Maybe a good idea to get a head start. I read in another thread that someone who did not open their pool for 2...

    Do I have Mustard Algae?

    Ok, Thanks. I'm continuing with the SLAM. Test results as of 2AM. FC-10, CC-0. I added 1 gallon of 12.5% chlorine to raise the CL level between 13-13.5. I see some of the black spots again at the bottom of the pool. Is it possible, as I brush and vacuum that the small algae particles go...

    Do I have Mustard Algae?

    As of 11:30AM FC'-9.5 CC-0. I added 2 gallons of 12.5% liquid chlorine which should bring FC to 16.5. As of 1:45PM. FC-13. In between the tests, I vacuumed some algae and pasted this pic. Is this an egg? What type of algae is this?
