Question regarding my Inteliclor IC 40

[dykes26]

I have an IC 40. I intentionally over sized the chlorinator so that it would last longer and not have to work as hard. In the hot summer I have had to set it at 60% to get proper chlorination. Is this normal?

Current relevant readings- IC Set at 60%

FC- 4.0
PH-7.5
CYA- 85
Outside temp 82
Water Temp 86- solar heated

Comments/questions?

Thanks and happy 4th!

A very important bit of information is missing.
How many hours per day are you running the IC40?

For reference/comparison, my cell is set to 20% and maintains a steady 3.5 FC and is ON just 60 minutes/day. Pump runtime is 10 hours but only 5 hours on a 25 GPM speed which turns on power via a relay to the IntelliChlor Transformer.

5 hours / 20 % = 60 minutes and I have verified this via the Pentair IntelliWand program output.

My pump run time is from 9:00 am until 4:30 pm on a low 1800 rpm setting. I do not know what the run time is for the IC. How do I check the clorinator run time?

Just for comparison, I run my IC40 8 hours a day at 80% to maintain 4.5 ppm FC in a 28.5 K pool. So your setting does not seem unreasonable.

I run my IC40 24 hours/day at 10% and it generates between 4-8 ppm FC in my 22,000 gallon pool.

dykes26, if your pool gets a fair bit of direct sunlight each day your numbers look reasonable. If the pool is heavily shaded I would look into things more.

Thank you! We get almost no shade. That explains it. Thanks to all that provided input.

And if your an SC Alum like me we like our pools clean and ready to party. Your settings sound ok and your other numbers look good. Basically the settings on the IC40 20, 40 60 etc relate to percentage of an hour that the cell is generating Chlorine. Besides your run time your pump speed will also make a difference.

On my 25K pool I run 40% for 12-15 hours a day to get 3-4 ppm at 1800rpm. I vary the settings based upon pool usage, sunlight and clarity of the water and FC levels.
