What started as a joking side comment between me and the gf, "I think at the rate we are finding stuff we like to put in the tank, we are going to need a 300 soon" has kinda turned into something serious. So looking to hear from the people that made the jump from something normal size-ish to one of the big boy tanks. Was it worth the switch? aside from extra water, extra rock, extra sand etc, what else am I looking at taking on as an additional cost/maintenance? I'm eyeballing a tank that would fit perfectly in the corner, granted the stand is a little tall, but the price seems to be right. or should I keep my focus on the 120 and packing that guy full of fun?
