1 Quart - Zero Phos

What it does

When phosphate levels rise above 1,000 parts per billion, a dose of Zero Phos will quickly lower them to acceptable levels in as soon as 24 hours. The 32 oz. bottle contains enough product to remedy a 20K-gallon pool and the treatment process is simple – add the product, watch it work its way through the pool system, and wait a day for it to complete the task. A follow-up test will confirm phosphate removal or let you know levels were high enough that you need another application.
