I ordered a k-2006 kit recently but after further reading it seems the tf-100 kit seems more appropriate. This is my first pool and is a brand new install. I've always had a family pool growing up but never managed the water. I paid $60 for the k-2006 but contemplating spending another $100 for the tf-100 and speed stir. Figured it's cheap considering the investment and will save $$$ in the long run. Am I on the right track? Should I return the k-2006? Is it worth hanging on too?
