Sump room build question...

[cobraz]

Can I get a few opinions on what pump to use for this application.
I am going to have 2 Food grade horizontal water contains sitting on a 2 x 4 rack.
Each will have heating and a stir power head that can be turned on separately. The rectangular containers will sit stacked one at 6" above a typical fish bucket.. the other will be approx 30" above the lower one.
The bottom will be Salt mix and the top just R/O.

Here is the million dollars question..I wanted to avoid carrying mixed salt water...in a 5 gallon bucket to the tank.
So I want to drop in a temp power head/pump..that will take the lower water 40' from the lower stacked container to the tank which the top rim will be appox at 5' (60"). The water will travel from ground 0 to 60" thru a 40' vinyl 1/2" hose.
So what power head/pump could I use...it must be submersible ?
Looking forward to your thoughts..

Sicce has a large one similar to the ultra zero but bigger. The ultra zero will do it but the bigger one is much faster. In our store the higher tanks are 60 to 70” from the ground and our pump has 60 plus feet of python tubing that it pumps through. If you have a sump you can pump into the sump and that would fill faster than the top of the tank.
