Jonas 3 lb Winter BorateTab Cartridge
The larger charge, for the larger pool.
The Jonas 3 lb winter BorateTab cartridge, part NJP0100201 and stocked under SKU PST-NJP0100201, is the larger of the two borate cartridges, sized for pools that need more buffering capacity to get through a closed season. It floats in the collar and releases borates slowly, holding pH steady while the pool sits with no pump, no test kit, and no one looking at it. That steadiness is what keeps the rest of your closing chemistry doing its job. The floating collar, part NJP10030, is required and is sold separately.
