We have used Baqua when we first got our Tiger River Caspian. We always had problems, so we switched to Nature 2. I got a bad rash from the clorine used with Nature 2, so had to switch again our chemicals. Now we are using Spa Guard Soft Soak (supose to the same as Baqua). We still have the same problems, foam, smell, and cloudy water. I was told by my Soft Soak dealer to try ***Spa Guard Natural Spa Enzyme***. You put it in once a week, and so far no scum line, no foam, and water smells and looks great. This product can be used with your Baqua. Any dealer that handles Spa Guard products should have it. This is what it says on the web site for Spa Guard:
Compatible with ALL Spa Care Systems!
SpaGuardŽ Natural Spa Enzyme
Natural enzyme formulation for use in spas and hot tubs. Helps break down organic contaminants, scum formation and odor. Water is clearer and overall experience is enhanced. Helps prevent oily buildup on filter(s).
Hope this helps. :)Lynnette
