I'm getting a 6 foot tank that is leeking from one of the bottom side seems. Getting it repaired by Trevor and he is modifiying my 3 foot tank to make a sump. at the moment I have a 4 foot planted tank but I'm getting board with it.(Selling it.)When I was 21 or so I had a 1m x 500mm x 500mm Marine tank, I swopped it for some scuba gear. (Now I miss it.) Tecnoligy has changed some what though; I had an undergravel filter and a canister. I'm told that is no longer used. Funds are a bit tight at the moment so I will do this properly and slowly.
