I’m looking at buying a used tank that is 270 gallons, it’s 7’ x 2’ x 2.5’. It’s an acrylic tank currently drilled on the sides with those black overflows. I’m interested in housing a stingray pup in here. I know that a sump would be the way to go for a tank this size, I just don’t have any experience building one. Can anybody point me in the right direction for what I would need to do this for this tank? Thank you!
