When we first got our spa we used Baquaspa and our water was never clear and ended up having a chemical smell after only 2 weeks of putting in fresh clean water. We decided it was enough and gave this Silk Balance a try. Ever since we switched to a chlorine base chemicals and silk balance we couldn’t have been happier. The water has never been clearer and it got rid of that nasty smell. I would definitely recommend this product to anyone.
