No the SWG ONLY runs when system pumps run.

Timer, 7am-6pm @65%

The builder added 45% sodium hypo. 8lbs then perhaps 5lbs 24 hours later. Chlorine levels 24 hours after the first dose rose to and remained fairly static around 17. This morning 24 hours after the second dose chlorine levels are around 16 LaMotte and 20 Taylor. CYA tests 13 LaMotte and 0...

Pool contractor added 8lbs shock this morning. Said they will return tomorrow and add 6lbs more, and make decision on wheather to continue with additional treatment. I checked what they added and it is sodium hypochlorite @45%. System has been set on 90% over the weekend. LaMotte tested FCL @...

OCLT test indicated a drop of 0.77 Free chlorine @6pm 9/28 was 4.59 Free chlorine @8am was 3.82

The ORP controller has been tested by Hayward and found to be working properly. This indicates to me that there is something potentially in the water consuming the chlorine. Perhaps the pool is in a chlorine demand situation, potentially created by an undocumented treatment for algae early on...

Since I have been testing with both the LaMotte and the builder is testing with Taylor, I have been able to draw relative comparisons between measurements. For example:if I test CYA LaMotte @ 30 and the builder tests with Taylor @40, and the pool store tests @35, I have established a...

The equipment rep (Hayward) tested my water and included nitrate test. Results were within limits. He then tested all of his equipment and found it to be in working order. So he set the ORP and said not to worry unless ORP drops below 500. It did not. However, chlorine dropped from 4 to 1...

Thanks for responding. I intend on maintaining my own pool however, as the pool is relatively new and under warranty, I am attempting to have it corrected by the well experienced builder, (perhaps 500 pools annualy) and the equipment supplier (Hayward). What I have thus far experienced...

Pool will not hold chlorine level when set on automatic regardless of the ORP set point. When set on % pool will hold and even generate chlorine. Pool construction company has been attempting for 2 months to rectify but has thus far failed. Hayward suggested lowering the CYA from 60 to 25 by...
