I feel you, Luis. My new 83 was supposed to be simple: tank, pump lid and off to the races. But I keep thinking of new things I want to do with it!The investment in the new tank is costing more than expected, I'm thinking of moving everything to the new tank and thus I save on things that I need and that I already have in the 32, powerheads, doser... but at the same time I'm a little scared that with the change of lights, flow and so on I'm going to lose everything I have.
