Product details

The Pentair Rainbow #335 is a floating dispenser for 1 inch bromine or chlorine tablets, part number R171090.

How it works

Load it with 1 inch tablets, set it in the water and let it drift. Sanitizer feeds slowly as the tablets dissolve, which keeps a residual in the water without anyone adding chemicals by hand every day.

Who it suits

It needs no plumbing, so it works for a pool or spa with no inline feeder, and it works as a backup when the installed feeder is out of service. Make sure your tablets are the 1 inch size before ordering, since 3 inch tablets will not fit this dispenser.
