Welcome to our forum.
The brown line is common with new spas, you will have to drain & fill in about 4 weeks. In the mean time just wipe the scum line off with a clean damp cloth. It is just residue from the manufacturing process.

Hmmm. Sounds a little bitter jsimo7 ...let it go!(Actually, I believe he already has one anyway!!)Froggy, The scum line is not necessarily caused by the manufacturing process (my Maxxus has never had one), body oils etc. are also causes. There are floating products to help absorb these oils such as Scumbug that may help you. I'm sure the aformentioned cleaning products will work to get rid of the ring you already have. Good luck!Steve
