From what little research I could find, it looks very similar to the Aquarite but I'm not sure on the reliability. It only has a one year warranty and you will be dealing with Inyopools to get any replacement parts and troubleshooting it will be difficult if problems surface. As you can see you didn't get much support here at TFP. I read that it is not made in the USA. It might be a great deal at $500 for the 40,000 gallon system, but that is your choice to spend double that amount for a name brand system such as the Hayward AquaRite with a three year warranty or the Crystal Pure.
