Hey guys so I friend just give me this and by looking at the manual it seems I have to drill my tank. I really don't feel comfortable drilling my tank is there another way to by past or is any Willing to come over and drill it.
What brand is your tank and what size? From there you can look to see if there bottom is tempered, if so it's not happening that way. If the sides aren't tempered you can drop them and use a weir overflow.
Sea Reef Sump - complete except for return pump. I bought it as part of a package with a new tank, never been used. It has all of the bulkheads, fitting, etc. including 2 gallons of black bioballs. The overflow is a nice piece. Really want to sell them as a package. $125 takes it. Nice...
