Hi there. Please help if you can. I have a 2118g swim spa that is 6mos old. We have had to drain it three times so far - it was recommended that we use a biguanide system and we use Leisure Time Free system (same manufacturer as BaquaSpa) I have an issue with the “goo” that accumulated on my spa water line, which is extremely sticky, and the stickiness is also like a “slick” on the water - the “slick” is not gummy and isnt sticky until you get out of the water and dry...then it feels like dried glue but sticky. We drained it, cleaned, pressure washed, cleaned again, drained again then refilled it two weeks ago and the issue came back within a week. The sticky slick settles on the skin making me sticky. (If anyone knows how to easily get the sticky off of our body, you would be my new best friend!). I added Enzyme and additional sanitizer, and the goo along the walls started to gum up. I can get the gum off with a scraper, but how do we get rid of the sticky residue it leaves behind? Even the floor of the spa is sticky (not as bad as the goo - but my feet stick to the bottom). Had to get in the water today to try and get the gum off - and I got out sticky with a slight skin irritation. I want to love my spa and I am using the Leisure Time FREE system (same manufactures of BaquaSpa. - no one sells Baqua here in Vegas). We cannot enjoy it when we cannot sit in it. The last time we drained it, the goo sticky was so bad, it took a day to scrape it off and wash the spa as it hardened like cement. I need help and this seems to be the place to go - I need a biguanide expert! Please help me love my spa again.
