thread on simplifies water change/plumbing ideas?

[dilligaf_biker69]

I know I have seen them...now I cant find any....need help building the plumbing for my 180...and looking for a way to plumb it where I can open a gate/ball valve to pump water from sump instead of back into tank to get to a water change level and then figure an automated way to pump new tank water in.....thanks in advance

T off a line from the discharge of your return pump, install a valve and the hose to the drain.
Use the mixing pump on your mixing tank to transfer the water from the mixing tank to the sump.
With a couple of valves and some piping in the mixing tank you can use the pump to either mix or transfer:
