Yup, just add pool salt, not sea salt or water softener salt.

Matching pumps to filters to plumbing is a bit of an art, but you want your filter's capacity to always be greater than your pump's or your filter will fail faster.

With an ordinary round or oval Above Ground pool, standard 1.5" PVC and TigerFlex will be fine. TigerFlex is flexible PVC but if you don't want it to leak, you must use it with glue-on Schedule 40 fittings just like hard PVC. Barbed fittings designed to go inside hoses WILL fail and leak if used with TigerFlex, no matter how many hose clamps you use.
