Back drilled tank.

[TopGun619]

Hello I have a chance to buy a back drilled tank. I have a sump setup that was overflow feed. I think I can just put the lines to the back holes but not sure how to connect them and get water to the sump. It's just the tank. So what I'm asking is what would I need to attach to the holes in the tank.

You need bulkheads, but it depend on where it’s drill on what you need to do, post pictures of the tank front and back.

These are the tanks. Only wants 60 a piece. I only need one. I have a sump but it only has 2 hoses. I don't think it's powerful enough to pump all 4. So may need to look at more tanks.

I assume you’re going to be using an external overflow. You’re going to need to make sure you have an overflow that is properly sized for where the holes are drilled so that your water level ends up at an appropriate height.

The tank has spots for a internal flow out. So I would make sure that those are right. I would plug one side as I only need one In and one out.

Bit I will have it all cleaned up. Was left in a house that was abandoned. The tank ran for about 2 months with no care. The fish were still alive. Gave them to someone with a good tank. I'm just starting.

It's was huge. About 6 foot long. 2 or 3 foot high and like 1 and a half deep. But the tank was about to bust.

you want to use both overflows, and a valve on your return lines.
if one clogs,will overfill tank, also will allow for more surface skimming ,and flow.

Use a couple of these if you want to go super cheap. No need for anything else but bulkheads and hose to the sump.

My sump has two lines. One pump draws in to the skimmer then it drops into the sump and another pumps it back to the tank.

what do you mean "about to bust" ?

They have a nice 65 gallon bottom drilled tank at my lfs that is 500. I may just buy it cause it will work for my setup at the moment.

The top was cracked so the glass was bowing and the seems were coming apart.
