Need help on a reseal plus tank id

[joshainga]

Just picked up a rimless tank that appears to be able to convert from all in one to rimless not really sure as it has a plug set on the bottom and a 4 chamber built in overflow with returns on both sides. Was told that it has a leak in one of the corners but it appears to have a plastic cover going up the seams as well. I’m trying to identify what tank set up it is so I can order some stuff for it and set it up soon. Dimensions are 35 1/2in x 22 5/8ths x 21 3/4in. It’s an awesome tank and I want to get it right so I can set it up. Would also be interested if someone has experience resealing rimless tanks as well to pay them to reseal it for me. Anyone have any ideas on who may have manufactured this tank or where I can look?

Tank volume is 79 gallons with a 15 gallon internal sump/overflow.

Not sure about this tank, but Waterbox used to make a marine starter version that was a conversion from their AIO to a sump version. So it could be run both ways if the drains were plugged.

Looks like I’ve confirmed it is a Red Sea E260 tank.
