If you're talking about your last set of pictures. Looks good, but you'd want to use 2x6's for the horizontal members likely. Your 147cm comes out to ~58". You may get away with 2x4's just fine. I'm not really sure what size tanks you're planning to put there. You're planning 3 racks to hold 3 levels of 20L tanks and 2 sumps on the bottom level per rack? And 2 tanks per level per rack? I don't think that's what you've said, but that's what your numbers correlate since a 20L is 30". How many tanks total are you setting up? 18 displays and 6 sumps? Is this right?
