Hi - trying to figure out why Jandy AquaPure isn't keeping chlorine levels up in pool. We've been using liquid bleach to keep chlorine up while we figure out the problem.
Water crystal clear
At the suggestion of TF pool members on another board, I did the overnight OCLT test - it was fine.
Another suggestion was to test the chlorine after sundown, run the SWG all night, then test again before sun up. I did that last night, and the free chlorine levels dropped from 4.5 to 2.5 (CC stayed at .5). The generator was set to 70%. We aren't getting any error messages.
Do these numbers suggest that it just needs cleaning? We haven't done that yet (we're new to all this.) Any ideas or suggestions would be very welcome!
