Don't forget you need breakers/fuses to drop from 6 gauge wire to 10/14 for the elements and pumps. Which raises the question are there currently any breakers/fuses to limit the pump outputs to 15amps?
Why would that matter? The pump is never going to source that much unless its shorted or something in which case the mechanical relay(looks like a standard Sainsmart 2 channel relay board) he appears to be using is going to pop. Their so cheap you can use that as a fuse of sorts
