I have a Sundance hottub, about 4 years now. I use Baquaspa chemicals (as recommended by the dealer). We have unusually hard water for our area and have had, over time, a buildup of a "white-ish" film on the silver parts of the jets and in the filter chamber on the walls. The hottub heater stopped heating past about 85 degrees, and has the code FLO. It was a faulty flo switch due to buildup of calcium, not under warranty due to "neglect". I have since been using baquaspa ph decreaser ( as recommended by the dealer) to remedy the problem. I now have the same flo code and the same problem, because the buildup is still in the hoses and it "flakes" off and gets clogged in the flow switch causing it not to work. My questions; how do i "cleanse" the system of the buildup in the hoses and throughout the rest of the system. Is there some chemical that will "dissolve" it? So I don't have to keep replacing the flow switch when it gets clogged? And, is baquaspa chemicals good to use? thank you for your help

Leisure Time has a chemical called Jet Clean. You add it to the spa prior to a drain and clean it acts like Draino but made for spas. It will release what is trapped on the pipes. If the build up is severe you may have to drain, clean refill and repeat the Jet clean process. As for the pH decreaser, what that is doing is dropping your pH to and acid level to try to get the calcium to release. There are other problems with attempting that procedure. If your pH is too low for too long it will "eat" any metal parts and possibly the plumbing in a matter of days. We have seen this happen where a new metal part was installed and the customer called us 15 days later reporting a leak. When we investigated the leak we found that the new part had been partially dissolved. Baquaspa Chemicals are better now that they were a few years ago. I am a certified Pool and spa Operator by the National Pool an Spa Association, and have been in the industry for over 7 years. I have found that Leisure Time is one of the easiest systems to use.
