We seem to be having issues with Baqua Spa leaving a film on the side of the hot tub. Water seems to be in balance. We moved to Baqua Spa after I seemed to develop an issue with bromine based chemicals (itching). Checking to see if anyone else has had this issue and/or if someone could suggest a different system. We tried the Frog Stick after I was having the itching issues. That worked for me but my wife starting having issues with itching. We have a Royal Spa Sultan spa.
Thank you for your input.
