If I were to start over from scratch, how would I find instructions that would make me succesful, and always have a plan to follow. What are the modern methods, from start to success? I would need something I could trust and really stick with. I have never been able to find someone I trusted to follow. I try to follow something different that sounds promising, only to find out. "Nobody is doing that anymore."
IMO these are my considerations as I'm planning to build a larger tank:
1. Go as big as you can in terms of gallons
2. Plan for your lines plumbing, outside air, WC, etc... for automation before hand
3. Large sump with lots of space for any upcoming upgrades or new technologies
4. Use APEX, and plan a clean wiring
5. Create a dramatic aquascape that you really really like and fish/coral friendly before moving to any other step. Look for inspiration in others builds.
6. Think about the methods you'll plan on using in order to plan for your equipment needs, eg. Triton, Zeovit, RedSea, etc...
7. Try to go +1 and/or very good quality in certain things, UV, skimmer, lights, pumps, refugium, reactors
8. Not using small grain salt, looks good but it's a mess
9. Plan to create areas where you will place your coral depending on their needs, eg. High flow, low flow, high/low light
10. Plan quarantine space
11. Shy fish first
12. If you want multiple Tangs plan to add them at the same time and as juveniles
And last but not least Bulk Reef Supply TV has a serie in Youtube about a 160g built - they go through every mayor aspect with a very good logic and sequence. I would strongly recommend you add much as possible. Is called 52 weeks of reefing.

Hope is useful, and again it's my personal view, I certainly have lots to learn.
Enjoy your new built.
