Bored into leaving
Having finally managed to arrange for someone to come and drill my new tank for sump installation I had a sudden thought, just how big a hole should it be?
The display tank is about 85 gallons and the sump is made of two 15 gallon tanks (pre drilled to link).
Will 32mm be an appropriate size hole?
Your thoughts, as ever, are welcomed.
