Hi guys, I just pulled the trigger on the 66 gallon Labor Day special, so I'm getting the tank, solid wood stand, and sump filtration. I have been out of the hobby for over 20 years so take it easy on me

. My ultimate plan is to have a small reef set-up, but we love fish so the emphasis will always be on the fish! I'd like to start with mostly fish, and perhaps some live rock, and then perhaps later transition to a mix of fish and corals, but nothing too crazy.
I have read through a lot of pages on this thread and others, and I have to say the information is a little overwhelming at the moment. I'd really like to take it slow with this build, step by step and (re) learning along the way. My fist priority obviously is to get the tank erected and the plumbing set-up, and then fill up with sand and water and some live rock and let it cycle.
While I have many questions, most of which I hope you guys can help me with, I want to start from the beginning and with the basics. So my first concern is the proper set-up of the tank. I will continue reading through this (and other) thread, but I would really appreciate a few hints or tips any of you may want to share regarding the set-up. The LAST thing I want to do is make a mistake and then have to end up draining the tank later on to fix it! I am also very concerned with potential leaks and I want to do everything I can to prevent them from happening. So here are my initial questions:
Plumbing - I have read about issues with the provided plumbing. Would it be better to replace it from the beginning with something better? I'll be going with a Herbie drain. BTW, I talked with Steve today, great guy!, and he said the plumbing provided now is all SCH40 so I will try to use as much of it as I can. I already ordered the gate valve for the main return line from Amazon. I guess I will just start laying it out and see what I can use and what I still need to get.
Return pump - I got Steve to take the pump out of my order and he recommended the Jabeo 12000. At first sight it seems a bit overkill but I see the merits of using a pump at 50% capacity or less and it lasting a very long time that way. Eventually I will probably want to take full advantage of the DC motor and use the pump in combination with an "auto-leveling" controller for the overflow. I have to read up on this some more but I am assuming this pump will be compatible for something like that...will it?
Lighting - Probably the hardest decision I had to make so far...I decided on a single Kessil A360WE for now. It definitely is much more than what I was willing to spend originally, but after seeing and reading about the awesome shimmer these lamps produce, I have to say I had no other choice!
Here a couple of things I will be looking at once the tank is set-up:
Starting the cycle process - Do I use live rock or dead rock and introduce cultures in a different way? What sand is best? - I would really like it to be coarse with lots of coral fragments in it.
Water - We have an RO system for drinking water and I plan on "piggy-backing" on it daily, transferring water to a storage container in the garage which I will then use for mixing in salt.
ATO - Here is where I would like some input, what would you guys recommend? The reservoir will be located in the storage space behind the wall.
Controls - I am a big techy and I love the ability to monitor and (perhaps) control systems remotely. I love the idea of having some sort of master control for all, or most, of the systems, and being able to control them from my phone. Therefore, do I need to be conscious of my particular choices of hardware I purchase from here on? - This is an area I really need help with. This includes pH, temperature, salinity, and any other parameters that can be monitored electronically.
I have a storage space behind the wall where the tank will go, so I plan to mount all the controls, gauges, etc on the inside wall of that storage space. I can also envision mounting a wifi security camera zoomed in on the controls to be able to monitor everything remotely should the "on my phone" option be to complicated and/or too costly.
Anyway, thanks in advance for any input guys, I am so excited about getting back into the hobby! My tank will arrive in about a week so I have time to do my research and decide on the best path forward.
