Water Chemistry

Our guide to basic Water Care is included with your spa Start-Up Kit. They are also available below for download.

If you need a new copy of the water care sheet that Mainely Tubs gave you when we delivered your spa,  we can send it by email.  The detail of those instructions depends on which ozone system is in your spa.  If you are unsure, you are welcome to call us at 800-479-7935 or email us at relax@mainelytubs.com. We'll look up the information for you and send you the right one. If you know for sure, download below...
