Between a rock and an algae place

[JJ_Tex]

Ok. I read all of this. I still don’t know how to figure out what I need to generate, how long. If I did the 4 hours as suggested on the SWG article, I would have algae every day! I do have the app. I coudl use some help on this, please.

If you use the "Effects of Adding", you can search for your SWG and put in your pool volume to play around with the numbers.

If you run 24/7 and have your SWG cranked to 100%, you will generate 9.3 FC per day.

In Houston you will probably need to generate roughly half that per day in the summer. That means you can run your pump 24/7 and crang the SWG down to 50%, or you can run your pump 12 hours a day at 100%.

I tested it yesterday morning and it was a 16.5 4 times in a row SO no I dind’t test it until today. So when I got home, it was 12.5.

The reason for that daily drop was most likely the sun because your CYA is (ow was) below the recommended level. Last I saw in your notes the CYA was ~ 50 and it needs to be at least 70. That helps to preserve the FC for a salt generator much better.

As for how to set the SWG or how long to run, it varies. The links I posted above in Post 18 are good articles. The PoolMath APP can tell you "about" how much FC is expected to be produced based on output and pump run time, but that's estimated (ideal scenario), so here's what I would do:
PREPARE:
1 - If you are still sure your OCLT results were good and you passed (algae-free), increase the CYA to 70.
2 - Set your pump to run 24/7 just for now.
3 - Set your SWG output between 50% - 75%.
4 - Test your FC now. Ideally it should be in the 5-7 range. If it's low, add some liquid chlorine to bump it up.
5 - Confirm your salt level is good (somewhere in the 3,000-3m500 range probably).

SWG SETTING/PERFORMANCE:
1 - Test your FC at the same time each day, let's say 5:00 pm for example. You "ideally" should not lose more FC than your cell can produce in 24 hrs. If the FC continues to fall after 24 hrs running 24/7 at 50%-75% output, then something is wrong (cell, algae, etc) and we can come back to that. So here's what you are watching. There are basically three scenarios after 24 hrs:

a - (Ideal) - The FC tested higher than the day before which means you can lower the SWG output or reduce the pump run time so it doesn't work as hard.
b - The FC remained steady at that pump run time (24/7) and output (50%-75%). That's better than losing FC, but we may need to find out if it's working too hard.
c - If the FC continues to fall after 24 hrs, we go back to the cell having a problem, being too msall for your pool, or algae.

It's really that simple - or should be. The only time your cell will struggle is if it's old, has a technical problem, is too small, or you have algae.

Make sense? Still have questions? Let us know.
