I have my theories but lemme ask here to see if I am missing something.
Have a 30,000 pool (125 feet around, my guestimates its 30k with a 10 foot deepend). Have a circupool rj60 that I installed last year. All the chemical balances are correct except the chlorine content. I am trying to get the chlorine to 3ppm. It does not seem to want to go past 1. Combined Chlorine is 0. Replaced Filter Grids and cleaned filter completely.
I dropped 2 to 3 gallons of liquid chlorine to get the pool up to about 5ppm, and it dropped to 1 or below in a day.
There is no debree in the pool, skimmers cleaned, robots cleaned, pumps cleaned.
Here are my 2 theories.
1) The CYA is too low. I believe it is at 15 or 20atm. I use pucks extremely sporatically because I know CYA is pretty much permanent.
2) There is algae growth that is stagnant. I don't see any but my other guess is that there is biologics, but the filter and system works so well that I don't see it. So its at a kind of break-even point where I can't kill it all, but there isn't enough in the pool for it to grow crazily.
Did a shock about 2 months ago.
Question 1), Should I wait till Octoberish/November when the temp's cooler and less light and do a month long shock of the pool? Essentially murder whatever could be in there and do a total cleanout? I am mulling over the usefulness of this. Thanks.
