Thanks for the advice, not trying to be stubborn, just trying to learn.
Checked the link (good one for explanation! Nice pictures/directions too
). Just think I can handle more than a "take it from us" answer for lots of reasons.
From what I got out of the link, the main advantage of the box was to be able to start the system back up when power turns back on, correct?
So if the overflow box remains primed, when water pumps back into aquarium and levels rise back to normal, water will drain back down into sump completing the cycle again... correct?
Otherwise, w/o the overflow box, the pump would return water back into the tank, but with an unprimed intake hose, water will gush over the edges of the tank... right?
I can easily afford an overflow box, so it's not so much a cost/diy
issue, just wanted to know what actual concerns would be raised if an overflow was skipped. Thanks again!
