I was thinking about creating the best constant (daily) automatic water change system to work with my Apex system.
I know a number of reefers use the Dos pumps to achieve this and I know that they also now make the Pmup pump that can handle a reasonable amount of head pressure.
Would 2 Pmups (1 for draining old water, 1 for pumping new salt water) or the Dos be a better way to go?
