Hello. I’m having a Radiant semi-inground pool put in later this spring/ early this summer and had questions about the startup chemicals. The dealer will get me started up, but after my wife did a lot of research on this website this seems like a much better method than the expensive chemicals available thru the dealer. Is it possible to do the initial chemical treatment in a new pool with the TFP method? The dealer also recommended an ozonator. Is it worth the extra cost? Any input would be appreciated.
