I want to add a 50 gallon low boy frag tank to my fish room. Its in the basement below my DT. I have several spots off of the return manifold I can get water from and feed into the frag tank but how do I get the water back in? The low boy I got I can drill so thats fine, the sump is Aqueon 55 and I cant drill it (Tempered). I have a few return pumps in my quiver that I can use but my issue is backfeeding during power outage or feeding. I have an Apex with some water level sensors so I could make a system where if the main pumps shut off and water fills into the frag tank at a certain level the frag return pump would stay on filling into the sump until the switch goes off and then it stops.
Any advice how to do this safely?
