Hello all! I am "new" to the saltwater hobby (about a year with a fowlr 55 gallon) and have just bought a 240 gallon tank. I am in the process of purchasing the equipment and had a couple of questions about the plumbing. I bought the tank on craigslist and it had 2 holes in the upper center of the tank and that's it. Could I just use 1 hole for the overflow and the other one for the return? I didn't know if one hole would be enough for the overflow and mag 12/18...(haven't decided yet) pump that I want to use. I also have a 55 gallon sump under the tank. This will also be a FOWLR tank. Thanks so much! Your help is VERY MUCH appreciated!
ALSO, IT DIDN'T COME WITH AN OVERFLOW BOX, SO WOULD I HAVE TO PURCHASE ONE OR COULD I JUST LEAVE IT OPEN WITH A "NETTING" ON IT?
