Many thanks for the kind words Shervin. Unfortunately we're still fish free and waiting to move (there's been a few hold ups) and i'm going slightly crazy not having any fish to look after. My trips to MFK haven't been as regular anymore since not having any but i will be back when the next build starts. Mrs Satan keeps putting ideas in my head, the biggest 'tank' idea we might try when we're settles is at 60,000 Gallons.........Damn we need to get moved!
