(IF-SM-CC020B) 20"x4.5" 24,000 Gal. Calcite Low pH Neutralizer Filter

Used this to bump my PH for selling my home. Worked great installed my existing filter system.

The first intelifil i received did not worked properly: lost water pressure from 50 to 10!. I called the company and told them my issue. They told me that the filter was clogging up. They sent me new empty casing, I open the filter casing and noticed that it was different than the original one, and re filled with the calcite from the old one.I installed the new filter and is working very good! 50 pds of pressure coming out and the ph increased from 5.25 to 7.50👍

Perfect for my filtering system

Like another reviewer said, right out of the box it didn't work -- barely any flow. Entirely unusable and had to pull from service immediately after installation.Waiting on response from seller
