I'm in the process of converting my pool to salt water so that I can use my new SWG system from Hayward (Aqua Rite) and was wondering if it is ok to use Diamond Crystal salt pellets (yellow bag). My local Costco is selling 50 lb bags for $4.99 and from the package it is 99.8% pure, however there is no indication on the package it can be used in pools. So my question is: is it ok to use this product in my pool? I know pellets dissolve slower than granular. All comments are welcome.
