After my first water change everything was great for a week. I went to my dealer with a water sample and he recommended a calcium additive. while I was there he showed me a product called Spa Perfect an enzyme product that is designed to absorb oils etc. and keep filter maintenance to a minimum. I added 130 mls to my tub and now I have a foam problem, nice three inch bubbly clouds ,when I turn on the air and jets. Now what do I do? I,m totally upset I added this stuff to my water. thanks ,bobhol
