How it works

Two-piece moulded HDPE chemical floater with central tablet column, threaded base and adjustable vent ports.

Tablets sit in the central column above the vented base. Water enters through adjustable ports, dissolves the lowest tablet face and releases sanitiser into circulation. Adjusting port aperture controls flow rate.

Tablets dropped loose into a tub bleach acrylic surfaces and dissolve unevenly. A floater contains the dissolution and lets you tune feed rate to match bather load and water temperature.

Why a floater?

Loose tablets bleach acrylic; floater contains dissolution to a controlled column with vented release.

Can I use it in a swimming pool?

For small pools yes, but skimmer feed is more practical at pool scale. Floater is the hot tub standard.

Sanitiser too low?

Open ports; add extra tablet; check water flow around floater.

Sanitiser too high?

Close ports; reduce tablet count; remove floater for 24 hours if needed.

Floater vs erosion feeder?

Floater is portable, fits any tub; erosion feeder is plumbed in-line for permanent installation. Choose by tub setup.
