SWG not producing much FC - passed multiple overnight tests

[hammocktester]

I have a Circupool core 55 SWG and I noticed in March that after about a year of use I’m not getting much FC production out of it. I done at least five overnight tests in the past 10 days or day and all are a pass of less than 1.0 FC loss.

Based off my current run times 13 hours at 100% I should get nearly 8FC but I might be getting 1-2 as it seems like it can barely keep my level flat through the day but I’ve had to add tabs and liquid to keep it up over longer periods of time. Last year at i could run it at 75% during the summer and at 100% my FC would climb up. I have a lot of trees around my pool so demand is high even if the offseason but I was able to have the FC climb and turn it down previously


Current stats

TA - 110
CH - 300
Ph - 7.6
CYA 50-60
FC - 6

Time for an overnight chlorine gain test.
Like an oclt but you keep your cell on all night to see what you gain in the darkness.

Also, check your cell for scale build up

As in run the SWG over night and see what it produces?

After sunset, measure FC. Turn the cell up to some known % and run the pump overnight. Test FC again before the sun is up. Compare the FC rise between tests to the expected FC output at your known %.

Normally I would say to increase the CYA to 80 but there is this other Circupool thread from a few months ago......don't know if it is relevant to your issue but worth a read.

Circupool Edge 25 not producing FC

My Circupool Edge 25 has been performing perfectly for the last year and a half. Monday morning I noticed the water was not sparkling like normal. I tested water. FC was only 1.5 when normal levels are 3-5. My CYA was low at 40 so added to bring it up to 70 where it normally is. I added bleach...

I did a ten hour overnight test and it produced 1FC at 100%. My pool is around 20k and the app says I should get 6FC. Even if my pool is 25k the app says I should get 4FC

What is your salt result with your K-1766?

 

[Mdragger88]

Once you’ve covered all the bases-
oclt, no scale, appropriate salt level via 2 sources, & ocgt its time to put in a warranty claim armed with your data.

Call circupool...

 

[wireform]

Your going to get from them some blah blah on what are your phosphates and let them know that's a non issue. Press them hard.

You are best to call them rather than do an online chat. I got more results from them by talking to the same person on the phone.

Resolved the issue, was a bad dpd test kit that was two maybe three months old. That said will never purchase a Circupool product again, they don’t answer their phone and are nothing but condescending over email. Was super unprofessional

So it was/is producing properly?
Hate to hear you had a bad experience w/circupool.
