Hello and hope everyone is enjoying the beautiful weather and large lakes you need to drive thru to get thru a intersection. Any who, Like stated im thinking of drilling my 125 and putting in a synergy overflow box. Question is has anyone used one of these and if so how many beers or drinks would it take to get you to come over and help. HAHA. Its on a pet smart tank and they say only the bottom is tempered so i should be ok. Unfortunately this is for my chiclid tank and not my SW tank. The wife and i have decided to break it down and do a frontosa tank with sand bottom so i need to plumb in a sump. Love how the wife says " stop spending money on the fish tanks" week later " we should sell all our fish and do just a frontosa tank with sand." lol. Also does anyone maybe have one of these boxes but never got to install and wants to sell it. Or does anyone have a rear drilled 125 that they would like to sell?
