I am getting ready to build a stand for a 75 that will be used as a "planted sump" for my 125. I will have the 125 overflow into the 75, and then use a couple canisters to draw back into the 125. My question is how should I line up the water levels in both tanks? Should they be exactly lined up before the canisters are fired, or should the 75's be a little lower?
Thanks!
