AlkaViva Vesta GL BioStone Plus Replacement Filter

Used in Filter Position 2 (right). Starting with compressed carbon block, we add Plus Technology by impregnating it with specialty media to increase contaminant reduction. It removes Chloramine, heavy metals and other tough contaminants better than the BioStone Basic.

Containing Scale Guard protection, it will outperform any GAC filter – regardless of micron rating. (Rated for 1,000 gallons.)

Note: will not remove heavy metals as well as the UltraWater filter does.
