Ordering a Magnum 90 spa from Costco next week. A few rookie questions. Has anyone used EZ spa pads as a base? Anyone used Nature2 to treat spa? Also anyone have this particular spa and care to give any tips as to what they would do differently with regards to delivery, installation, etc.? I have already decided to order so I am really looking for advice to help my learning curve. Thanks in advance for any advice/answers you may have!
