You are my age and already have a 1800g I have a 55g and I'm trying to get something bigger but it's been a hassle, Plus I'm in the same situation with my family, They don't support "Much" of the "Big" ideas I have but I think I'll be able to convince them one day. Anyways Gratz on the 18,000 Gallon Pond!!! Where did you get it? If you ordered it what website?
