For this I have been using Leslie’s to test. I find their chlorine tests reasonably accurate. Then also test with a strip (I know-I’m not a fan of strips either but for TC and FC I find them accurate as well).

Thank you for your reply. I was never a fan of ahhsome. Tried in the past and found SLAMMING to be far more effective. However - since it isn’t working now you are right that I should try ahh some or another purge product again.

I have SLAMMED the heck out of my spa but cannot close the gap between free and total chlorine and cannot get rid of chloramine odor. I’m ready to install a UV system. Worried that it is some chlorine resistant bacteria and will not go in spa until I can clear it.

Thank you!

A few questions: 1) Are you piping the CO2 into the pool pump through the drain plugs like Circupool and Poolsmith? 2) If so, I noticed Circupool and Poolsmith systems have a second plumbing line for pressure and Circupool says their system cannot operate without the pressure line. How do you...

I will check it again, but I have virtually no buildup of any kind on the plates. What little there was I was able to blow off.

That's the thing - no visible scale at all in the cell or on the pool tile. My CSI is typically well within range.

That's what I am thinking. It is very clean, barely ran last year (ran at 25% for a few hours per day). Worked with Discount Salt Pool - they will take it back and bench check it. Was trying to exhaust all other possible issues before sending it back. The overnight test was my final step -...

Would hardness on the higher side impact SWCG production? I have had to run it a lot more than last year. Last year 2 hours gave me plenty of production. Is 8.5 hours at 50% really too short to judge? That was overnight, so no burn off.

I think you got it - I had more borates in the water than I thought. Per the pool math app that would explain the smaller reduction. Not sure that explains my SWCG production though.

If anything it is smaller than I have it entered at given that I have not subtracted for my steps. 15x35 with 3' at the ends and 6' in the middle.

It can go higher. Combo on the numbers - I have found the store to be off on pH and Chlorine so I do those myself.

Okay - it happened again. Added the pool math recommended amount of Muriatic Acid to get it down to 7.2 from 8.1 and it only went to 7.5. Also, did an overnight test on my SWCG. Pool math says based on run time, run % and output of my cell I should have seen a 2.8 ppm gain in FC over the 8.5...
