So....Dilemma time....
I called DSP this morning, got quickly transferred to the senior tech guy, who quickly transferred me to a manager.
They are clearly not used to customers armed with a wealth of pool chemistry and diagnostic information (probably because most don't have a clue about their pool chemistry

). They definitely would not be testing for 'Quantity of FC Produced'.
I think he understood what I was generally unhappy about, though didn't entirely buy my argument because in his mind there are "just too many variables to measure"
Somewhat to his and the company's credit, he saw he had a bad situation on his hand with an unhappy customer and did offer a full refund upon return.
So....do I return it?
The U-55 if it got anywhere close to 2.9 Lb/Day was an incredible deal. If it's getting 40%-50% of that (which it probably is), it might be getting a bit less production than the top capacity Hayward or Pentair SWG's, at maybe $500 less. Whether it lasts the same lifetime...who knows at this point?
So if I am not going to go back to lugging jugs, it might be best to swallow my pride and keep it and start shopping for a Variable speed pump, which will definitely be needed.
I did propose to him a refund of 50% of the purchase price because it's getting 50% production and I keep the unit. He thought that was just too goofy!
I'm taking a vote! Who says I return it and who says I should keep it!!
