Hi! I’m just going to be straight forward. My son is 15 and has a 90 gallon tank. He is only running a canister filter for now but has been waiting for some stuff that came from his uncle to set up a sump. He is building his own sump right now and doesn’t even know where to start since his uncle is on vacation. Can someone please help us? I will attach pictures of what we have right now. I don’t have a picture of the return pump but I have it.
