There is a thread on SWG operation in this forum. Check it out.


.....IN, this section?obviously? I'll have to go back further.
thanks

I can assure you that when the pH is at 8, chlorine production is at an absolute minimum. What little that is produced is immediately used up before it can get into the main body of the pool.

The only way to find out if there is any Cl production, is to sample from one of the return jets. I use a 3/4" flexible hose pushed into the return, and the other end into a sample bottle, under water.

The cell could start scaling up making things worse, as it is a new pool.

The 10 ppm more than likely came from the liquid chlorine added. Until a complete water analysis is posted, everything is speculation at this point.

Keep on adding the acid to maintain the pH from 7.2 - 7.6, brush, brush, brush, and vacuum to waste. This will take time, so persistence is needed here. Hang in there.

sorry, I gave incorrect info before when I said what the tech did when he came out. All he did was add acid to bring the PH down......VOILA.....THE Chlorine is now 10. (not from adding chlorine) Yes, too high, but with all the sun / heat we are having here, it will come down and we brought the output on the SWG down a hair.
The tech also added stabilizer.....he said don't touch anything until I come back (he'll be back Wed.) I think the problem was the PH was too high and the unit wasn't producing chlorine as someone mentioned.
We weren't adding enough acid weekly....only like 1/4 gall. Wasn't enough. We think that 3/4 gallon will do it....but not touching it now till he comes back to check.
