Welcome to our forum.
My experience has been that enzymes are a nice maintenance additive...something you use on a weekly basis before you have trouble. Â It will keep you water smelling fresh and "eat up" oils and soaps. Â Clarifier is something you use when you are already in trouble. Â Use it sparingly when your water is cloudy and won't get clear. Â It will usually do the trick.Having clarifier on hand is a must, even if you rarely use it. Â Enzymes are a luxury.
What  do you think of the 4-in-1 product then?  By looking at the directions, it would seem that I would use 1 oz weekly for maintenance (like using enzyme) and double that dose if needed, for cloudy water  (clarifier).  Thanks! Â
I have no experience with them, but don't those scumball thingys absorb oils and stuff without adding chemicals to the water. Â I don't add anymore goop to my spa water than I need to either. Â But I've not had an oil slick problem to deal with so far.
