I have a glass 55 gallon tank with an hob overflow box, I was reading that a tank should have atleast two drain lines to the sump/refugium. I don't have the room for two overflow boxes, do I really need them to drain the tank?
Can I use PVC to drain the main tank to the sump or some other type of method of draining?
I would like to have one drain to the sump and another to the refugium, then have a return from each one?
