Help choosing above ground pool

Hi. I’m looking at replacing my 18 foot intex temp pool with a real above ground pool.  Namco is having a sale on some nice pools.  I’m looking at this one:  https://www.namcopool.com/above-ground-pools/wilbar-element-52-deep-above-ground-pool/

Question is, I’d like to do salt as I had that in my intex and really liked it.  This pool says it’s “salt compatible”.  The guy at the Namco store told me I’d have to get a sacrificial diode in order to make it salt compatible.  But this is listed as mostly resin, other than the steel wall.  Shouldn’t this suffice as a salt pool?

It wouldn’t hurt to have a sacrificial zinc anode. It’s going to protect any other parts that the water may contact throughout the pool and equipment. We typically recommend a zinc anode for any salt pool.
