Representative with Spa Pool & BBQ Show is misleading people about having to add chemicals to the H2X Spa with the Eco Pur Filter. Was told we did not need to add chemicals to spa, this was a big savings. All we had to do was drain spa twice a year and put in a new Eco filter once a year. This is not true after reading the manuel from Master Spas. This was a big selling point to us. Maybe we are just naïve to have thought this. But they should not be telling customers this. I have not received by Trainer 12 spa yet, so will let you know later on that.
