I hope someone can help me with this. Until 3 weeks ago my Hayward Aquarite had been working great in my 10,000 gallon plaster pool. At a duty cycle of 24% the FC would climb. At a duty cycle of 22% the FC generally held steady to a slow decline. Now it seems to barely work.
Recent history:
- 23 days ago: FC was 7.5 at a 22% setting. I lowered the setting to 20% (as measured by going through the diagnostics because the printed knob settings are not accurate).
- 15 days ago: FC was 4.0 at the 20% setting. I raised the setting to 23%.
- 8 days ago: FC was 2.0. I raised the SWG to 35% and added .2 gal 10.5% Chlorine.
- 6 days ago: FC was 1.5 and CC was 0. I added .4 to .5 gal 10.5% Chlorine to get the FC back to a comfortable level and put the SWG to SUPERCHLORINATE for the afternoon. FC came up to 5.0.
- 5 days ago (about 24 hours later) the FC measured 5.0.
- 2 days ago: FC was 4.0. Taylor salt test showed 3600. I adjusted SWG hours from 7 to 9 per day and raised it to 70% duty cycle.
- Today, after 2.5 inches of rain and 2 cloudy days: FC at 3.0. The SWG appears to be producing because I observe bubbles coming from the return jets when the SWG shows current (no bubbles if current is 0). I took a water sample from one of the returns and measured 6.0 FC so I know the SWG is generating. I just don't know if the production has fallen off a cliff from this test.
SWG info: New OEM control board about 1.5 years ago and new (late Sep 2023 install as my Hayward t-9 only lasted about 2 years) Circupool DIR-GEN15 Aftermarket T-15 replacement cell.
SWG diagnostics:
30.1 volts when not outputing chlorine
25.1 volts and 6.86A when outputing chlorine (had been 7.01A a week or so ago when I tested the salt level at 3600. Note: I fired the pool guy about 2 months ago when he dumped salt in on 2 successive weeks causing the SWG to read 3800 and temporarily shutting the SWG down and driving the FC to 12, and regularly letting the ph to go to 8.4.)
Chemistry today (Taylor K2006 kit plus Taylor salt test and recently calibrated digital pH meter. Added 20oz acid two days ago):
FC: 3.0
CC: 0
pH: 7.5
CYA: tested at 70 two days ago (typically kept between 50 and 70)
Salt: 3400 (was 3600 before the rain) (Instant salt test at the SWG reads 2900 or 3000)
TA: 70 two days ago
CH: 3 months ago: 600 (Rarely tested. I've seen it as high as 650 at the end of the dry season and as low as 325 at the end of the wet season.)
Thanks
