Install a whole house nitrate/nitrite removal system. System includes: - Clack metered regenerative/backwashing cation exchange water softener - Clack metered regenerative/backwashing anion exchange water softener - Two brine tanks and first salt fill of 10 bags (5 per unit) - Clack regenerative/backwashing acid neutralizer with calcium. Calcium is a sacrificial media and it will need to be replenished annually. In the event the PH crashes below 6.2 a more aggressive mix of Corosex and calcium may be required to balance the PH with a target of 7.0.
