FC Level with SWG and Low CYA

[djpool21]

We've converted to a SWG about a month ago and CYA is 50. I'm holding off a few more weeks until increasing CYA to 70-80 at the end of pollen season, spring rains and frequent back washing. I've been targeting about 5-5-1/2 for FC level now, but I'm wondering if my target level could actually be lower. What do you think?

I am no expert and I have a SW pool. I don't know where you live, but if your water gets up to 88-90, I Personally, do not let my FC drop below 5. I have found over the years that if you get busy and forget to check or something happens, you have a little wiggle room....just my .10

If your FC is able to hold in that range with a CYA of only 50, it's fine for now. I would not go lower. The pool and swimmers are still well protected/buffered from the chlorine by the CYA.

Thanks. I’ll continue with my target of 5 to 5-1/2.
