    In Ground Spa Draining Into Pool

    I saw a post on a related problem where the pool owner had tried to fix the problem using an aftermarket check valve flapper, then based on advice from TFP readers, replaced it with an OEM valve and that solved his problem. So I did the same, replacing the aftermarket flapper I had used to get...

    In Ground Spa Draining Into Pool

    I did the test and the spa did not drain, so I replaced the Jandy check valve and it drained half as much overnight, so that was a help. Any suggestions on what else is needed to stop it draining altogether?

    In Ground Spa Draining Into Pool

    I have 2 check valves and I'm not sure which is failing. After the spa had refilled I turned off the pump and disassembled both check valves as well as the Jandy valve and everything looked fine to my unprofessional eyes. I would have expected the water level in the spa to drop while the valves...

    CYA won't rise

    It was the same product. I added some last year and it seemed to work then.

    CYA won't rise

    Back in March my CYA was 50. I added 5 lbs of conditioner (ClearView primo powder Pool Water Conditioner & Stabilizer 99% isocyanuric acid) over the course of a few weeks and it didn't budge. That was using a sock in the skimmer. A little over a week ago I added 43 more ounces this time with the...

    Adjusting Calcium Hardness Level

    Thanks for all the feedback. This is why I love this site. :) Isn't a drain and refill essentially the same as an exchange? Our rain mostly comes in July. We might get some spring rains in April. Also regarding the CH test itself, for me when the color of the water changes, it goes from red...

    Adjusting Calcium Hardness Level

    Moved from HERE Since my CH was at 900 and my CYA had spiked I decided to do a water exchange. Here are my readings before and after: Water Temp 62 degrees F BEFORE AFTER FILL WATER (TAP) PH 7.9 7.9 7.9 FC 7.0 4.0 0.5 CC 0 0 0 TC 7.0 4.0 0.5 TA 70 100 100 CYA 100 <30 (the black...

    Zodiac LM2 Control Unit running very hot

    jdtessi - what was the outcome of your experiment? Was there a difference in the temperature by running the chlorinator at a lower level? I have an LM2-24 with the same problem.

    Water Exchange with Algae

    I woke up this morning to zero overnight chlorine loss, no sign of algae and the water was already sparkling yesterday, so I'm done SLAMing. I turned my SWG back on, added stabilizer to raise CYA and added acid to lower my TA. Thanks again for the support, and especially for the quick responses...

    Water Exchange with Algae

    The SLAM is going well. My pool looks much better, thank you all. I've been regular in brushing and adding chlorine, which leads to my next question. I've seen the directive to add liquid chemicals slowly in front of a return repeated so many times there must be some reason for doing it that...

    Water Exchange with Algae

    I added CYA yesterday and today (sock isn't big enough to hold all I needed to add at one time) and expect it to be completely dissolved by morning. In a different post Brett S recommended waiting for 24 hours after all the CYA is dissolved and then test the CYA level again to confirm it's at...

    Water Exchange with Algae

    I was not expecting this answer so I added salt last night. Does that change what I should do?

    Water Exchange with Algae

    I bought a small 1/3 hp submersible pump and did the exchange over 48 hours and it's now done. Here are my new readings: Temp: 81 degrees pH: 7.8 Salt: 1000 CH: 350 TA: 160 CYA: 0 TC: 0 The Chlorine/CYA chart article seems to indicate I shouldn't SLAM until CYA is at 70. Am I reading that right?
