I'm actually looking forward to changing water
with this setup it should be a snap- I'll know exactly how much water to take out based on the water level of the mixing tank which will drain into the QT tank fairly quickily with a 1" drain pipe. It's basically just a matter of turn a few ball valves and wait a few minutes and open a few more- instant, simple, and safe water change....hmmm...unless I have a fish in QT I guess
. In that case I guess I'll just have to drip the new mixed water directly into the sump after I drain the sump a bit- still pretty easy but I'll just have to monitor the water levels a little more.
