Intellichlor not making chlorine, algae growing
My 36000 gal IG Gunite salt water pool was completed about 4 weeks ago. I have the Intellichlor IC 40 chlorinator.
I have had the unit set at 50% since "poolschool." However, I have kchecked my chlorine levels by color change and dipstick simultaneously about every other day and have always had what looks like zero chlorine (the water in the tester is CLEAR). I now have algae in my pool again. I first noticed algae last week and skocked the pool 5 days ago. The pb tested the water the day after shocking it and it had 0.3ppm by his testing. I suspect it would have been 0 if I hadn't shocked it the day before.
He suggested increasing the intellichlor to 70%. Suspecting that the chlorinator wasn't working at all, I increased it to 100% and restested after running continuously for 12hours, 24 hours and 36 hours. All retesting at 100% chlorination setting produced results of zero or essentially no chlorine each tome, even after 36 hours. The Intellichlor indicator lights are all green indicating it should be operating and functioning normally but this doesnt seem possible to me. My pb says leave for few more days at 100% but that seems unreasonable. Do I really
need to run it this long at 100% with zero chlorine? What should I do?
Initially my pb put in chlorine sticks on two occasions otherwise I think algae would have grown sooner.
Initially the pb put in chlorine sticks before I st
