Product details

The Pentair Rainbow #300-29X is an offline commercial chlorinator, part number R171070. It is a heavy duty, high capacity tablet feeder for large residential and commercial pools.

Capacity and output

The feeder holds 29 large tablets or 237 small ones and dispenses 8.5 lbs. of 1 in. trichlor tablets in 24 hours. That output treats pools from 80,000 to 322,000 gallons. Across its sizes the Rainbow range covers pools up to 658,500 gallons.

How it works

An offline feeder is plumbed beside the return line rather than in it. A heavy duty 1/2 in. control valve and tubing meter the water that passes through the feeder, which optimizes flow and erosion of the tablets and lets the unit deliver larger amounts of sanitizer. Slow dissolving trichlor or bromine tablets both work.

Note on chemistry

Pick one tablet type and stay with it. Trichlor and bromine should never share a feeder.

Questions and answers

What people ask about this product, answered by our pool techs.

How big a pool will this feeder handle?
It treats 80,000 to 322,000 gallons. The Rainbow feeder range as a whole covers residential and commercial pools up to 658,500 gallons, and this is one size within it.
How many tablets does it hold?
29 large tablets, or 237 small ones.
What tablets can I use?
Slow dissolving trichlor or bromine tablets. Never mix the two chemistries in the same feeder.
What does offline mean?
The feeder sits beside the plumbing rather than in the main flow, fed by a tapped line. That lets the control valve meter how much water passes over the tablets and therefore how much sanitizer goes back to the pool.
