This is my build in the springs. I designed mine to upgrade as I went (as you will see) and for my wife to take care of the system while I am deployed. I just deleted the posts that came up along the way so that it is super easy to read with a ton of pics. Pics are sideways because it wouldnt't let me rotate until I got a new phone. Sorry for the kink in your neck.
Some suggestions from me:
-Incorporate a sink
-Understand what kind of reefer you are. I have seen a ton of people buy a calcium reactor or other high speed expensive equipment and then not use them at all. Are you really going to perform maintenance eveyday? Are you really going to go downstairs and check everything everyday?
-Plan for the future and not for now. Odds are you will end up wishing you had a frag flat and a quarantine set-up
-Don't use typical house lighting in your filtration room. The spectrums will make you hate the corals and nems.
-Flooring and bottom half of walls should be easily cleaned. (I drop water on my floor and don't even clean it up.)
-Anticipate floods and electrical panel overloads.
-Have a backup return pump and an electric resupply in mind (backup generator or battery backups for heaters and powerheads).
-EVERYTHING should be easy to get to.
-Dummy down all of your maintenance process so friends and family can manage for vacations.
-Keep small kids and animals out of your fishroom.
-Incorporate a small fragging/tinkering station with a heavy duty vice clamp.
-Anticipate salt creep and rusting metals (plumbing, tools, steel window frames and light fixtures)
-Think about ventilation and/or a dehumidifier
-Invest in dc pumps and save yourself some coin in the long run
-Hang a tv so you dont get blamed on selective hearing.
-Have a wireless router or relay installed in your filtration room for faster response times and updates from servers (only if you plan on having a controller). (Strongly recommend an apex.)
-Automate or ball/gate valve everything.
-Plan a simplistic top off system.
-Eliminate any possibility of getting on your knees for regular maintenance.
-Leave space between your pvc joints for additions and changes.
-A small freezer/fridge combo is awesome to have.
-Have a trashcan and towel hooks.
-DIY as much as you can. Alot of the hobbiest keep their longevity because livestock stays alive and the pride in their creativity and craftsmanship.
Lastly, take your time. When I plan anything for the system, I research and ask around (like you are doing now) and then go to the drawing board. I place the drawing in the bathroom and leave it there until my next visit. I sharpshoot every negative aspect and then quickly mitigate the problems or redesign. You will know when it will be right.
