Besides my main pool, I also have 680 gallon spa with plumbing completely separate from the main pool.
Pump: Super Pump 700 High Efficiency 1.10 Total HP
Filter: SwimClear™ Single Element
Heater: Universal H-Series Natural Gas 150,000 BTU Low NOx
Chlorinater: Pentair R171096 320 Rainbow Feeder
Chlorine: 17.5
pH: 7.6
Alkalinity: 60
CYA: 30
Heat: 100 degrees
This pool sees about 1-5 hours a week where it is being used and uncovered. The rest of the time it remains covered.
I’m trying to figure the chlorinater out. When it was installed, they put in two 3’ chlorine tabs. This made the chlorine off the scale (10+) but I didn’t have the FAS-DPD test kit at the time to get more specific. Eventually, over a span of two days, it went from 10+ to 0 and the water was cloudy.
I did water changes to take care of that and this time I put in one tab and opened the dial on the pentair to 2, until the free chlorine got to 1.5, then I changed the dial to 1 until free chlorine got to 3.0, then I turned it off. All the way off.
I walked away for a 3-4 days without testing, and I got an FAS-DPD kit in the mail. I used the regular testing kit again today and the free chlorine was again, 10+, even though the dial was all the way off/shut. When I used the more advanced testing kit, it showed that my free chlorine is around 17.5! In all cases combined chlorine is <0.5, water is clear, everything else looks fine.
Inside the Pentair tube I can see that the tab has completely dissolved and the tube was full of water, even with the valve shut.
The adjustable valve for the chlorinater is good, I took it out and tested it, and the check valve doesn’t appear to malfunctioning, as I can see it is shut when I turn tue pump off and take everything out of the pentair fill tube.
What am I doing wrong here? My installer has either ghosted me completely or went out of business, and everyone else around here is understaffed and/or won’t send anyone out to look at it. Is it that this particular feeder is overkill for a 680 gallon spa that sees very little sunlight and people? Is there another way to go about chlorinating this spa if that is the case?
Thanks!
