Superior Calcite

I have a vortex tank and other brands would flush out of the system during the backwash cycle. This calcite is more dense and stays in the tank.

2.0 acid neutralizer

Easy install. The tank was missing the media fillport cap. I sent them a message and one was supposed to ship but I never received it. I was able to repurpose the one off my 15 year old softner. PH is now between 6.8 and 7.2.

Had to cancel order

The company was very responsive, I give them credit for that. There was a part unavailable and it pushed back production for 3 months, after another issue came up I said forget it I need a refund and they handled it quickly and professionally.

Just had this installed last week, did the ph test today and am very pleased with the results. We had our copper pipes replaced with pex pipe and so we had the plumber install the unit. He had a difficult time putting the calcite in it with the funnel it came with because it didn't fit the opening, but used something else he had. It's been a long time waiting due to shipping issues and the pandemic, but I am glad I did wait because I am pleased with the final results.

A Great Acid Neutralizer

Very, very swift (free) shipping!

Looks good and upped the PH.

Not something a regular homeowner can install himself. The total price of unit plus cost of plumber saved me $400 dollars over using a water treatment company in my zip code. Side funnel designed to fill system should have been included in the price paid.
