I need to replace my Hayward T-CELL 15 SWG cell. I've read that the electrodes on the aftermarket products are thinner and wear out faster. I've seen Compupool, Titanium Power Cells, and the T-CELL 15 ULTRA (from a recent post). Anyone have a suggestion? I want a unit that is plug and play - I don't want to have to modify my setup at all.
