Jonas 1-1/2 lb Winter BorateTab Cartridge
Holds pH steady while nothing is circulating.
The Jonas 1-1/2 lb winter BorateTab cartridge, part NJP0100101 and stocked under SKU PST-NJP0100101, is a prefilled borate cartridge that floats on the surface of a closed pool and buffers pH through the winter. pH drifts when a pool sits with no circulation and no testing, and drifting pH is what undermines the algaecide and the stain and scale preventer you paid for at closing. Borates hold the line. The floating collar, part NJP10030, is required and is sold separately.

What do borates actually do?
