I have had a Pool Pilot installed for approximately 1 year 1 month. The installation was smooth without any problems. Last summer I was able to maintain a 4 ppm FC by running the Pool Pilot about 3 hours per day. Early this spring the SWG was maintaining the Cl level.
About two weeks ago I noticed that the Cl level had dropped to 1.5 ppm. I kept increasing the per cent run time and added bleach. When I reached 100% purifying output level I knew I needed to research what was wrong.
My water chemistry is as follows:
FC: 1.5 Cl tested with new FAS-DPD powder.
CC: 0
pH: 7.7
TA: 110
CYA: 70+ tested with a view tube
CH: 220
Borates: 30
Salt: 3,300
I did a overnight test and lost no FC or less than .5 FC. No organic problems. The pool is crystal clear.
I have completed an acid wash of the plates. The plates look good; no sign of scaling and no erosion of the end plates. The cell strainer is free of debris. The Check System light in not on. There are no error messages. The tri-sensor appears to be working properly. The salt reading of 3,300 is consistent with test strips. The temperature reads 85 degrees which is close. Originally I had the Cell Power at 1 with a 20 volt and 5 amp reading. This volt and amp reading has not changed since my installation day. I went into the Installer Menu and changed the Cell Power to 2. The Test Menu now shows Power Level 2 with 20 volts and 6.2 amps.
When I place the SWG in Boost Mode I do not see small bubbles in the water stream from the return. Previously I would see a milky stream of small bubbles from the jet. A water sample taken from the return shows FC levels of 2.5, 3.0, and 3.5 over the past two days.
Summary: I have sufficient CYA and no algae. All the Pool Pilot displays appear normal and the plates appear to be in good condition. Minimal Cl is being produced. What should I check or do to resume Cl production?
