No other pic. The barrels are interconnected which is why the description states you can pump from one or both barrels. Rh side also has a re-circulation loop to help mix salt.
Up for sale is a great little saltwater mixing station. It consists of (2) 30gal interconnected barrels and was used for 30 of RO/DI and 30 salt mix. Panworld 590gph pump can pump from either tank or both. Selling as I'm building a 200gal version for my new tank.
$125 takes it home.
