1. Set up auto-top off
2. RO water for top off - better if it auto-fills with emergency overflow
3. Plan for power failure
4. Choose one: a good lid, or high freeboard glass, or non-jumping fish
5. Rinse your sand prior to filling tank, otherwise can take DAYS to clear, and re-clouds every time you re-scape
6. Make sure your algae scrubber is big enough
7. Make maintenance as easy as possible (access, intervals, etc.)
8. Choose animals and corals that match your ability to care for them (feeding) water quality etc.
9. GFCI everything
10. Analyze failure modes and severity of equipment / power
11. Vertical waterfall algae scrubbers are a game changer wrt needing so few water changes to manage NO4
12. Shimmer is WAY better than disco-ball
13. Ensure that tankmates are compatible, hiding places really help!
14. Follow good practice, and advice of experience, a lot of companies selling expensive, unnecessary equipment
15. SPS and heavy stony corals add a huge level of complexity
16. Bigger is WAAAY Better
17. Unions in plumbing are key for adjustments/dissassembly
18. Run fuge/ATS light counter schedule to display
19. Some fish are fine with once a day feeding, many are not!
20. Many fish require some algae in the tank for optimum health
21. Let nature find the balance in your tank. Stressing bubble algae? Get emerald crabs for example.
22. Fish stores are not all created equal, For example, in my area one is 50% higher priced on livestock. The difference? They quarantine all SW fish for 28 days.
23. Make sure you can reach everywhere in your tank.
24. Plan for hot summer days, and AC outages.
