Reagent No.4 Solution
Brand: Aussie Gold
Chemical Type: Chlorine Neutraliser
Reagent No.4 Solution, a replacement for a manual test kit. Used to remove the chlorine level from pool and spa water prior to carrying out acid demand and total alkalinity test. Remember maintaining pH and Alkalinity balance is one of the most important aspects of pool and spa care. Chlorine must be removed from the water sample prior to testing for pH and alkalinity in order to receive accurate test results. Pool or spa water that has free chlorine will not give true readings for both pH and alkalinity.
