In some situations, the ORP reading can continue drifting up after chlorine production stops, especially around dusk/sunset. Is that what is happening for you?
Yes, the orp was that high at the end of the day. Are you living in my backyard? lol jk. Seriously, is there anything you don't know about pools? You're an encyclopedia. Hey, I'm not complaining, I'm very grateful.
Now the orp is 532 with (600) setpoint. Here we go again...
FC 7.5 this morning.
If I have to, I'll reduce CYA yet again.
Aquaman, how dare you enjoy this holiday weekend while I have pool issues! lol Hey, I thank you for all the replies. Have some fun.
I haven't checked cya again. I've used all my chemicals up from the test kit. Replacements are coming in the mail! I would say 40 is a good guess. I doubt it would change much from 2 days ago.
When you say "Still producing chlorine", do you mean the display showing.
"On" after the orp reading? The PP display says "orp 532 (600) ON" or sometimes it doesn't say "On" after the reading and setpoint. I didn't notice if it said "on" after the setpoint was overcome. I only noticed the FC tests kept getting higher with the test kit.
I have a question about how to read the orp display. What is normal function of the orp display? Is it supposed to stay at setpoint or very close to it like the PH setpoint? My ph never drifts more than .02 from 7.5 while the orp of course is all over.
So normal readings should be, for example, 590-610 while the setpoint is at 600? When it goes over the 600, the cell turns off. When it goes under 600, the cell goes on? Is that all I'm looking for?
I just want to know what to expect to see when all is working fine.
IF all gets working fine.
Hope everyone is having a great holiday. Thanks again!
