the secret is never to panic, when things go wrong, take a step back
issues to keep an eye out for
1. ammonia - the un-invited guest, keep seachem prime or safe handy, or even prodibio stop ammo
2. temp - need to keep temp stable, stops the fish stressing and keeps PH from shifting to much, also helps keep dissolved oxygen in the water
3. Stability or Special Blend to keep water in check, before , during and after. also a good idea to use prodibio travel safe or seachem stressgaurd
4. plan - dont waste time
5. dont worry about aqua-scaping, first goal is livestock preservation, add rock and corals and fish so they all fit and let them adjust for a few days after to keep stress levels down
6. Make sure target tank water is right temp, ph and salinity
7. keep lighting to the minimum, no need to watch your stock stress, look at them before you move
8. have about 30% spare salt water
9. if you cant get sump running, or leaks, place heater and skimmer in tank as temp solution, use egg crate to protect livestock from heater and pump
10. keep hyrdogen peroxide handy, good for adding O2 to the water if needed, 1ml per 100L
11. start on a friday eve or early sat morning, leaves time for emergencies and shops
12. get friends/reefers to help, less stress for you
13. make sure food and drink for helpers
these are a list of issues i have come across over the years, its not as stressful as it sounds
