What's the difference between Calcium Scale & Silica Scale?
Calcium scale and Silica scale look very similar and are often confused with each other. The easiest way to tell them apart is to test them with an acid such as vinegar or muriatic.
Calcium scale will bubble and will disappear. Silica won’t react at all.
Aqua-Rex will NOT remove Silica scale. The scale around the grout lines of tiles generally comes from behind the tile and is mostly Silica. Aqua-Rex will not be effective on this kind of scale either. High levels of Silica are found in a few ground water supplies.
Aqua-Rex will reduce scale in a filter so the sand is free to act more effectively and may require less backwashing. It will help chlorine or other biocides to be more effective so that the amount used can be reduced for the same effect.
Aqua Rex & Phosphates?
Aqua-Rex has shown to be effective at causing phosphates to flocculate and fall out of solution into the bottom of the pool. The water will be clearer and any algae will have less food so is less likely to cause a problem.
It may also help reduce dissolved solids by encouraging them to precipitate into suspended solids which can then be removed by the filter.
Is Aqua-Rex Waterproof?
Pool Unit is fully waterproof so it can be installed outside.
Aqua Rex WK1P Pool unit is IP66 rated, but the Electrical transformer that plugs into the socket is not.
What electrical outlet does it need?

How has Aqua Rex been in Business?
While Aqua-Rex is a new product in the US for the pool market, it is a tried and tested product in the UK and Europe.
Aqua Rex has been in use for over twenty years in its role as a water softener alternative and as a treatment for Long String Algae on Koi Carp ponds.
Over the last four years we have evaluated its performance on swimming pools in the USA and since April 2013 it has been a listed vendor product with Poolcorp. In every field where it has been evaluated it has performed as well, and in most cases, better than expected.
Does Aqua Rex get rid of all scale?
Aqua-Rex will get rid of Calcium scale but will have little or no effect on Silica scale.
Silica scale is only an issue in a few areas of the country where Silica rich water is drawn from wells. Silica scale won’t react to acids such as vinegar or Muriatic and can only be removed by using abrasives.
Sometimes you will find all the scale disappears and then a thin layer recurs, especially around the grout line. This is most likely to be Silica, and Aqua-Rex nor any device on the market is able to remove it electronically.
Can Aqua Rex help with Bead Blasting my Pool?
YES! it does help.
- Calcium scale on tiles and pool walls breaks up and falls away. Stops calcium scale along the water line. Saves from bead blasting that saves you time and money.
