What is the recommended CYA value for normal use?

[caliskier]

Hi I am about to finish my SLAM, my current CYA is 30. I’m wondering if I should raise it to 40 just to keep the chlorine burn from the sun down.

What are you guys keeping your CYA at?

What Are My Ideal Pool Levels?

Use our tool to find ideal chemical levels for any swimming pool. Check TFP recommended levels on pH, free chlorine, cyanuric acid, and more.

In very high UV areas (S Texas, Florida, SW Desert) for normally chlorinated pools a CYA of 50 ppm would not be outside of reasonable.

I'm a bit further south than you are, and I find 50 to be my sweet spot.

Thank you sir! Great chart! Really appreciate this forum

I’m curious, with that level of 50 how much chlorine are you putting in a day at 14,000 gallons?

I run a stenner pump for my chlorine, in the heat of summer with fresh bleach (12.5%) the pump runs for a total of 1/2 hr per day.
The pump is rated at 10gal/day. (24hr run time)
I buy 55 gallons at a time. (once per year)

Wow! I need to look in to what you are doing. Was thinking of a SWG

In my book the SWG is the way to go, with a Stenner pump a close second.

I installed a Stenner because I knew I would be selling the house before I could get the value out of a SWG.

My Stenner Install - July 2014

Well, I decided I love the TFPC method, but didn't care to carry bottles out to the pool every day. I was torn between a Liquidator and a Stenner, but for my install the Stenner won out. A little background. We purchased this house in November 2013 and the pool was already there (our first...

I would vote for a SWG.. then you don't have to lug the 55 gallon drum .. I love my SWG. It was the best investment I ever made for my pool. With a SWG there is a slight modification to the CYA/CL relation. No doubt you saw that in the chart: FC/CYA Levels
One year I added my CYA incrementally to see if I could detect a difference.. and sure enough, when I got the CYA within range according to the chart the chlorine retention was much better.
