Installation is negligible. Just bought a RJ-45 for my 13,500 pool. Cell life IS what the warranty is based on. The bigger better cells give you control of more things with their control box.
I would prioritize cell rating as #1. A cell that produces more needs to run less time to make the same FC. Less runtime equals a proportionate amount of longer life. You'll buy a 50% bigger unit for only 20% in cost. Future you will LOVE it.Is there a specific property or feature that I should prioritize over others? Maybe lifespan?
Yes. Some, like the Pentairs have an internal flow switch, and the others have a seperate switch that you also have to plumb in, but PVC work is easy and you'll be proficient by your 3rd attempt at it. I recommend getting a scrap piece of PVC and some fittings to practice. It'll cost $15 to learn.Is the installation difficulty pretty much the same among all of them?
I would avoid the SJ Series. The design of the cell allows air to build up, exposing the cell plates at slower speeds.So I have been looking at discountsaltpools.com. I tried the wizard where it asks for pool size and locations and these systems (among others) come up. I am a bit lost on what I should be looking for. Just looking at one brand, the wizard recommended 3 options
circupool sj-45 - $1059
circupool universal40 - $1259
circupool rj-30 - $1359
circupool rj-45 - $1459
