Product Description

Eliminate wastewater and reduce your energy use with a GreenFlow™ pH system. This upflow system reverses the normal flow of water through the media bed, eliminating the need for a backwash. Since the media works through the process of dissolving, you still get effective treatment of low acidity water without electricity or wasted water.

Service Flows
Service flow rate is the manufacturer's recommendation for maximum neutralization of low pH at a constant flow. Intermittent flow rate and/or higher pH levels MAY allow higher treatment flow rates. In most applications intermittent flow rates of 2-3 times the rated flow rate MAY be possible.

    Good Value pH Neutralizer

    Posted by Jose Macho on Oct 21 2021

    Ordered with the 3/4" fitting mistakenly thinking it was a MPT threaded connection similar to the 1" option.. On delivery found it is a solvent PVC fitting which is what most sellers offer with the Clack up flow system. After spending hours finally found the needed part# Clack V3007-18 which the seller did not offer. Ordered the part elsewhere so I now have standard 3/4" threaded flex hose connection for easy tank removal and no adaptors.
