So I finally got my mixing station built. Dual 55 gallon barrels and an 800 gph pump. In the salt side the return comes in towards the top of the barrel, goes to the center and to the bottom where it tee's towards each side with elbows facing opposite directions to create a whirlpool to mix. The problem is salt still sits on the bottom of the barrel. I probably dumped the salt too fast, but figured the whirlwind would mix it. I removed the downpipe and drill 3 holes in the arms at the bottom, with little difference. Any suggestions other than bigger pump and dump the salt slower?
