We are looking at a Lomart Whispering wind 24x52 pool. We have two of the ladders from our Easy set pools. Can they be used in these steel pools? The package we're looking at (on Ebay) is pool, liner, cleaner only. We'll need to purchase a salt filter in addition to the pool. Any recommendations on the best size to go with? This package is also through poolsupplyworld. Are they a good company to work with?
