Eco One can be used with chlorine, bromine, Baqua Spa and Nature2.  While we are aware that lots of people use Eco One with out any other sanitizer we are not fully comfortable recommending this.  The following system e have found to be very easy to follow and giving extremely nice clean water.  So why use Eco if you still need other products? click here to find out

1. Add bottle of Step One to old spa water and run as normal for 7 days.  You may continue to use the spa during this period.  Do check sanitizer level as they may spike or drop as Step 1 spa cleanser can cause unused chemicals to be released.  This must be done even with brand new spas as most manufactures "wet test" their spas allowing things to grow.  You will want to re-add Step one spa cleanser every other drain and refill from here on out.
2. Drain spa water after running step one spa cleanser for one week.  Clean spa surface as well as spa cover.
3. Install a nature2 cartridge in filter compartment.
4. Refill and add 1 ounce of chlorine granular per 250 gallons.
5. Check pH and adjust to between 7.0 and 8.0
6. Heat spa to desired temperature.
7. Add Eco One Spa treatment.
8. Add 2 caps of Eco One Filter Boost in spa filter compartment (or skimmer)
9. Enjoy your spa!
