Sorry Tony that i took so long to get a better pic, but here you go..

All i do is look at the # before i start pumping water out.
In the resivour, i didnt want to run 2 pumps, so i came up with a way around it.
Part of the problem for me was that the water from the res. to the tank had to cross a doorway, so my option was over the door, or under.
Under was the only real way that i wanted to see that, but i didnt know what to do with the water that would stay in the piping after a change.
In a week i would guess it woulda went stagnant.
So i came up with this
Now when the water change is done, i open the little blue valve,wich is connected to the intake of the mixing pump, and it pulls the water out of the plumbing via a veturi.
Works better than i had hoped, but now i just need to upsize the pump to a mag 7 or 9, that way it doesnt take so long to drain it.
Marc.
