Last summer I replaced my Hayward T-15 cell for a new one. The old cell, before it failed, consistently produced between 4 and 4.5 PPM. The new cell only produces 1 PPM of chlorine, both last year and this year, which seems to be cutting it close. My CYA levels are the same as last year. Here are my numbers:
CC .2 (maybe less--1 drop)
Salt 3100(per test 3200)
Lights are ON and Generating
Pool run time : always 8 hours per day during daytime
I called Hayward Customer Service multiple times and they have told me the following:
1. Its my Phosphates. I bought a kit and tested them at 125, treated with PhosFree they are now 0 (zero). I disagreed
with this course of action but they insisted this is my problem. Still have 1PPM of chlorine
2. Now they are saying its my CYA. I told them the CYA level has been the same as when I was using the old cell which produced 4PPM. I will not increase
the CYA levels with a potentially defective SWG given the CYA/Chlorine tradeoff..
3. Now they are saying its my Nitrates---I don't know how to treat Nitrates.
My water is crystal clear and I never had one day of green/cloudy water. I have shocked the pool twice with bleach to 13PPM with less than 1PPM overnight FC loss. I am even testing the water at the pipe that enters the pool.
I hesitate to call customer service again since they always insist the SWG if fine and its the chemistry causing the lack of chlorine generation. I hesitate to shock the pool a third time but I will do what is necessary. ANY SUGGESTIONs on why this new cell can only produce 1 PPM vs. my old cell at 4 PPM.
