New pool (2 months) that has hayward aqua plus with t-cell-15 for up to 40,000 gal. I also have a nature 2 sanitizer for 25-35,000 gallon pools. My pool is about 26,000 gal or so. My understanding is that by using the nature 2 it allows you to run your chlorine generator below the usual 1-3ppm and you can, in-fact, run the chlorine generator below 1-3ppm (.5ppm) and still have adequate sanitization of your pool.
I was told that I should be able to run the cell at a much lower % (25% or so or even less) due to the assistance of the nature 2 and that will greatly prolong the life of the cell. For the past 2 months the readings for the salt generator have hovered around 3600ppm, but on my test strips they only register about 1200ppm. This has been pretty consistent. I do taste some salt when swimming and they did put about 18 bags or so in when starting the pool 2 months ago but I have read a lot of posts that say the Hayward aqua plus readings could be off.
My issue is I keep all of the chemistry readings perfect (ph 7.5, Alk 100, CA 200, and CYA on test strips read between 30-50ppm and read much lower on my LaMotte Color Q photometric tester...usually single digits). However, my pool is around 90 degrees and I understand that can artificially lower the readings due to the high temperature so I have not paid too much attention to CYA on photometric tester.
The water looks clear and blue there does not appear to be any algae, the sides have no scale or slime, however I am running my salt generator at 45% and still every few days the chlorine levels are dropping to .2 and below unless I superchlorinate at 100% for 24 hours. I have done this almost every 5 days or so and think that I should be able to run the generator lower and should not have to shock that much based on what was told to me when I purchased. The pump is normally running for 10 hours every day.
It is a back yard pool that does not have a ton of bather load, just kids and occasional friends 3-5 days/week. I want to find out if 1. the salt generator is working properly (does not seem like it would need to be serviced already), 2. that the salt readings are correct (3600 vs 1200 on the strips), 3. Some other issue that I am not aware of or missing? Any help as to what it could be would be much appreciated.
