I use a couple of 30-some-odd gallon containers that I got from Wal-Mart. 13 bucks each, lids included. One has a float valve and is constantly topped off with RO. I pump RO to the other one with an MJ1200 and a hose to mix salt. The "salt can" has 2 or 3 cheap powerheads and a heater in it. I use the same MJ with tube to transfer saltwater to a container for water changes. Keep the lids on and RO and salt water stays clean. Leave the lid off and the salt gets all murky. If draining the salt water can, be sure and unplug the heater or the glass will crack.
