I need some ideas for sump designs. It's a 65g tall sump for a 120h fatboy tank. I am willing to do any customization needed to make it the best. I was thinking a wet/dry with refuge and protein skimmer. Will I need any more spots for filtration? How big should I give each area? How high do I keep the water level. First time running a sump so I was looking for more clarification if power runs out and over flowing and keeping it from overflowing cause I do not want it to happen ha. I have both pictures of the tank to give you an idea. Also i am building the over flow in my tank cause right now the tank has caps over the holes that are drilled. So how big should I make the overflow box around the hole. U circled where the hole are. Any advice is appreciated thanks ahead of time.
