All-natural product for reducing CYA in pools

Cyanuric Acid (CYA) buildup has become a cause of concern for many pool owners, and it is virtually unavoidable. CYA is added to Chlorine to stabilize it and keep it from dissipating into gas within a matter of hours in the sun. Unfortunately, Chlorine does eventually evaporate or is used up in sanitizing your pool, leaving accumulating CYA in your pool as you replace the chlorine. 

As CYA builds up over 100 parts per million (ppm), the Chlorine becomes less effective. Therefore, many people to have to maintain higher than normal chlorine in their pools or resort to other expensive and harsh water treatment products to maintain clear water.

The Problem:

When your pool has too much CYA, the free Chlorine isn’t able to function as an adequate sanitizer. So, you will likely be experiencing what many in the industry refer to as “Chlorine lock.”

Our Solution:

Until Bio-Active entered the market, the most effective way to reduce Cyanuric Acid buildup was to drain part or all of your pool water. This lead to water waste, CYA pollutants in the water ways, and expensive pumping, re-filling and chemical balancing costs.

In contrast, Bio-Active Cyanuric Acid Reducer is an all-natural, biodegradable, non-toxic product. It employs natural processes to decrease CYA to an optimal point so your chlorine can function as efficiently as possible.

No waste – no pollutants – no adverse effects to your pool!

How It Works:

Bio-Active Cyanuric Acid Reducer decreases your levels of CYA by speeding up the processes that already exist in nature. Cyanuric Acid Reducer disintegrates CYA at the molecular level. Furthermore, the proprietary blend of micro-organisms and dextrose are designed with a natural feedback loop and, if pools are in the proper condition, will reduce CYA down to recommended levels and then stop working. Although, for pools with CYA of 200ppm or higher, this may require more than one dose.

Note: Your chlorine will attack the active ingredient in Bio-Active Cyanuric Acid Reducer, so make sure your chlorine is at normal levels, around 2 – 5 PPM. We suggest reading the Get Started document below for full directions on how to prepare your pool.
