I just got a Pro Clear Aquatics sump/filter. I wanted to make my own overflow by doing the following
getting one large and one small lee's specimin container
putting the small container in the tank with holes drilled for water movement
putting the large container next to the small one with a siphon tube running from the small internal to the large external box
drilling a hole in the bottom of the outside box for water drainage and using either PVC
pipe of flexi hose to connect it, will this work?
