Is it time?

Is it time to raise the CYA?
The pool was finished in December. Brought CYA up to ~30 over the winter and have been TFP’ing it. Now the water temp is generally around 70*, I am thinking it’s time to raise the CYA?

s,

Yep!! I would bring your CYA level up to 70 or 80 .... You just need to make sure that your FC stays at the recommended levels per this chart... [FC/CYA][/FC/CYA]

I assume your IC60 is online and working??

What does this page look like in ScreenLogic???

Thanks for posting,

Yes IC60 is working. I have output set at 50% right now and salt level shows 2900, although test shows 3,000. I plan to add another bag of salt in the pool as well to get me in closer to 3200ppm.

s,

Until you get a good feel for how your pool works, I suggest that you keep an eye on your FC level.. 50% sounds high to me, but of course it depends on how long you are running your pump.

No one can tell you what your percent, or pump run time, needs to be, it is just something you will have to play with to match your pool's FC demand... Also, it will slowly change as the weather changes.

Thanks,

I have been testing more frequently now that the temp is warming up. Over the winter, FC is pretty stable. Now that the temp has warmed up, I was running it at 40% for 8 hours and I was “losing” about 1ppm during a sunny day. Where I am, it’s windy so there’s a lot of stuff that gets blown into the pool. I was thinking between that stuff in the pool and the low CYA, that’s why it’s using up the FC?

S,

Increasing your CYA to 70 or 80 will help slow down the loss of FC and should allow you to reduce your cell's output percentage..
