They certainly are fun to own! 600 is a lot...you can get a lot for that I think. Wonder how long it'll be after you've got your first until you want another one There is SO much info on these forums, and so many helpful members you'll probably hardly need the book if you do get one Also, tub over aquarium Oh and well done for checking out all the facts and everything first, sensible Can't wait to see pictures, and have fun!
