I spent more on impulse buy then anything else. Now that I know what I want IE, tank size, filtration, stock, etc....I can save and buy all at once instead of buying, then returning then buying again then returning and so on. Bought 12 tanks ranging from 55gals to a 700gal pond. Got rid of all the tanks, fish, filters (kept 3 FX5's), etc and bought a 830gal, 750gal (in the making) and a 350gal (in the making).
