drilled holes in aquarium??

[lionpicasso]

i bought this 75gal from some people who had holes drilled in the bottom of the tank. i thought it was for ugf but the more i read could it be for a sump??? my tank is 48" long and the 2 holes are 10" away from glass at each end of tank.
Thanks

sounds like a sump..hope they didnt miss-drill the holes

the holes could also be used as an overflow.

Best thing I've ever done is get a pre-drilled tank and a sump/refugium. Lucky you!
You can get overflow / return kits pretty cheap- all you have to do is silicone them in place, and hook up PCV plumbing. Its a little odd to have the holes at oppostite ends of the tank, but you could use one for overflow and the other for the return.

you can also use them both as overflows because if one gets clogged you still have water draining into the sump instead of overflowing....
