92 Degree pool, should I keep the Chlorine high?

[guisep]

My local pool company suggest 5ppm FAC... current numbers
FAC 5ppm
TAC 5
pH 7.6
TA 110
CYA 80

Things are good now but I want to keep them that way..

Any suggestions for anything else?

With a CYA of 80, you should be keeping a higher FC than that. Chemgeek's chart in the "The Stickies" recommends 5.8ppm as the minimum FC and around 9 as the ideal level for your CYA level.

Your numbers look good, though as JohnT said, your FC is on the low side.

There are some helpful links in my signature that will help you take charge of your pool.

Thanks for the info.. I'm running a salt system so I guess I'll pump up the output and retest

Well, with a salt chlorinator, the chart doesn't apply. You can even go a little lower than 5ppm and be fine.

As John says, with an SWG you can go lower than the minimum in the chart. Around 3 ppm FC for 60-80 ppm CYA seems to be about the low limit. 2 ppm FC or lower produced algae in several SWG pools. A very few pools even had algae at 3 ppm and needed to use the minimum FC in the chart, but they are the exception. I think that the superchlorination in the SWG cell over multiple turnovers plus the consistent dosing prevent the free-floating green algae from growing.

Thanks so much guys.. This is my first SWG so I'm learning as I'm going.. I'm glad I found this site..
