Do I absolutely NEED an internal overflow? Is this what will prevent me from overfilling my sump in case of a power failure? I haven't filled the tank again, since I built the Durso. If I make a modification you suggest, making a plate to go around it out of acrylic, can I get away without an overflow?
If worse comes to worst (and I get more aggravated), can I forgo the sump intirely and just buy a hob
skimmer? Will a skimmer along with adaquate lr
and water flow be sufficient for filtration, or would I need to add some kind of mechanical filter?
It would be an 80gal fowlr
set-up - eel and a few other fish.
Thanks for all your help.
