I opened my pool early this week and shocked at the suggested level (20ppm) given my stabilizer level (80 ppm).
At what chlorine level can I safely put my Polaris 280 pool vac?
I tested chlorine today and its down to 11 ppm. I'll start up the SWCG once it gets down to my target maintenance level of 5 ppm.
Do I need to wait until I get to the target level before I start using the Polaris?
Personally, I've never worried about that. I think they are more temperature sensitive than anything.
I didn't think about temperature. Is there a minimum temp you would recommend? Right now the water is running around 60 degrees.Quote:

Differently manufacturers have different low temps. I think the robotics say "60" but I've run mine in colder water with no problem.
Thanks. I'll contact Polaris and see what they say.Quote:

It's recommended for the cleaner to run in water no cooler than 65 degrees F. This is because the hoses can become firm with cold water and will dictate the path of the cleaner....
It's just been that kind of spring...nuthin's been easy! :)Quote:

Last year the strips and the SWCG read about the same. I'm afraid this might mean my cell needs to be replaced. I went ahead and shut off the SWCG and added 50# of salt (that should raise it to 3200 based on the strip test). I'll try again tomorrow and see what happens.Quote:

Comments?
Check CL yesterday and CL dropped by 1.5ppm. This is the same rate of decline that was occuring before the SWCG was turned on, although unlike the rest of the week it was sunny and warmer all day yesterday. Initially I set the SWCG to 50%, so I increased it to 60% to see if that helps.
The SWCG panel's readings all look fine; seems like if the cell wasn't generating CL like it should I would get some kind of indication on the panel? I'm hoping by increasing the on time CL will stabilize, but I fear the cell is getting ready to die (this will be the 6th season using this T-15 cell).
Perhaps I should start a new post.....
