How it Works

The ‘Original’ Enzyme Solution…Proven 100% safe and effective for over 20 years…

Try our product and you will see why…

There are over 3 million different types of enzymes and still counting

There are 14 different enzymes in the Bio-Prepase Water Treatment & Conditioner formula. Thousands of different formulas were tested over a period of years to find just the right mixture of enzymes that were effective.With this formula, we have a combination of enzymes that have been effective but at the same time 100% safe for people, plants, animals and our environment.The Bio-Prepase Water Treatment & Conditioner enzymes have some fascinating properties. Most enzymes work within a narrow temperature range – between 70 and 90 degrees F. At the lower temperatures, the enzymes don’t have enough energy to start a reaction. As the temperature rises, they work better until they start to break down from the heat.

These Bio-Prepase enzymes are different because they continue to work all the way up to 180 degrees F. Very few enzymes can tolerate – much less thrive – at this temperature. Most Enzymes are lucky if they last a week, our Enzymes do not gas out. The Bio-Prepase Water Treatment & Conditioner enzymes also have a long shelf life up to 5 years.

The Effects of Bio-Prepase on Water

pH – The pH of water is determined mostly by contaminants that enter the water supply.For example: soap residues, dead skin cells, lotions, human waste, urine, etc..  These contaminants will cause the water pH to rise and/or drop sharply.  Until now, the only method to resume a normal or balanced pH would have been to add chemicals to the water to reverse the problematic pH symptom.  Although adding a chemical will reverse the pH and provide you with a normal reading using standard pH testing procedures, the contaminant that caused the pH problem remains in the water, in addition to the newly added chemical used to reverse the problem pH readout.  pH testing is done because chlorine and bromine only work within certain pH ranges.  Bio-Prepase maintains it’s own pH range regardless of the contaminants entering the water because Bio-Prepase eliminates the contaminant without the need for pH adjusting chemicals.  These enzymes bond to the contaminant that enters the water (by using naturally occuring technology).  The contaminants are attracted to these enzymes and are captured in the filter.  This action occurs whether the contaminant is acidic or alkaline.  The pH level will fluctuate somewhat between 7.8-8.2, depending on the amount of daily contamination, but will usually stabilize within normal range without using any chemicals.

Color, Clarity & Odor

These enzymes help to remove organic contaminants from the water helping to prevent turbidity resulting in unpleasant water conditions. Inorganic chemicals that disturb water clarity are unaffected by these Enzymes. If necessary the addition of a natural clarifier will remove inorganic contaminants.


Due to the positive charge carried by these Enzymes, mineral particles will not attach to plumbing, pumps, manifolds, etc.. they will remain in suspension until captured by the filter. Certain exceptions in areas of hard water (that have not used a pre-filter may need to add a stain and scale control or metal out product.


Our Water Treatment & Conditioner is compatible with (chlorine, bromine, ozone) Sanitizers.
Our Water Treatment & Conditioner is not compatible with Biquanide products or 1-Micron Disposable Filters, switch from these disposable filters and replace with a regular pleated filter before starting with our program. Also remove any in-line cartridges before starting as well.

“Your customer service is outstanding.”
Beth / Pennsylvania
“I have owned hot tubs for over 12 years now. I was always struggling with the pH and making sure the water was clean. Sometimes when I’d turn on the jets it would make me cough really bad. It was a real hassle having to add chemicals every other day. But now with the All Natural Water Treatment, all those problems are gone. I have been using the All Natural Water Treatment & Conditioner for over 3 years now. My wife loves it because it doesn’t dry her skin out and it makes me feel good knowing that when the family and I go into the hot tub it is safe for our skin and lungs. Thank you so much!”

Price, Quality, Great Service and Install!!! We Could have never afforded an 18 x 33 oval of this quality and we looked in every local store all the way to Raleigh plus all the internet sites, pools of less quality with less product in the pool packages were 1500 to 2500 more. Thanks for all your help" Johnny Wilson NC
"Bought the Contempra and saved $1500 over Namco's price we love the pool and going into our third season with it. We got the Ozone and Mineral System we ordered and installed it in a snap just like you said, the pool is crystal clear without hardly any chemicals and the water feels incredible. Thank You I thought we were going to be stuck with the chlorine tabs forever because the pool is all steel but now we have the best of both worlds, the best looking and different above ground pool anywhere and the new system is as easy as a salt system. I highly recommend your pools, service and expertise to everyone looking for a great deal on a great pool and support they can count on" R. Marie Cornwall N.Y.

My Pool was installed two weeks ago and I made the mistake of going to the local pool store and having my water tested. They sold me all kinds of stuff and the pool still wasn't right, After our conversation on the phone and you having me use the test kit that came with the pool and you telling me to add alkalinity up then test again in an hour worked with just adding a little ph up after that. The Pool is water is clear, salt and chlorine levels are right on and I'm returning the unopened stuff from the pool store. Benson Nc
I wanted to thank you the Grand Bahama above ground was exactly the pool we needed. My kids are rowdy and the pool is built so solid it just takes all they give it. The 10 inch thick Resin frame is amazingly strong and the salt system makes it so easy and inexpensive to Take care of the pool. Tom Garner NC
Thanks For all your help we are starting our second season with the Paradise Oval we just opened it and the water is perfect, I put in one bag of salt and turned it on a we are good. I"m glad we got the Paradise it made it through the tough St Louis winter no problem Thx Marty St. Louis MI
