Hi Everyone, I'm looking for a bit of advice. This is year I am going to make the switch over to Salt. For my setup and power availability (only 1 outlet available) I am going with the Aquatrol. I have a question though, is it possible to replace the cell with a larger size down the road, for example going with a T-Cell 9 or 15 vs. the 5 that comes with it? I don't worry about producing enough chlorine on the 5 but would just like to avoid having to replace as often while still using the same control board. Thanks in advance!
