Hi, this is my first attempt at keeping Marine Fish. I have built my own corner tank and sump. Has anybody ever had any experience of housing their sump outside? I was thinking of digging a hole in the ground and putting the sump in a well insulated box in the ground, really just to keep the noise and mess out of the living room. Baring in mind I live in the UK and can have slightly harsh winters. I would appreciate any thoughts on this matter. Thanks Gary
