i spoke to 22 glaziers in my area for my latest tank build, cheapest quote i got was around 115 for 6mm glass, i then spoke to a friend who said wharf aquatics sell tanks and may do the glass. so i ring them and the glass woulda cost me 40! but then i asked how much the asambled tank would be, the reply was 41 LOL
so if u live close to M1 give them a call. i asked for the braces to be moved from the edge so i can get my overflow in and 2 glass lids. this bumped the price up to a massive 47 quid. lol best fish shop i ever had the pleasure of doing busness with (picking up the tank on thursday)
