AIO reef newbie

[parvicrazy]

Been in the fishkeeping hobby for many years. Had saltwater fish but never kept corals. Want to get an AIO system. Seems Red Sea is the way to go. Debating Max E-260 vs Reefer 250. Thinking about mixed tank with SPS, LPS, soft corals, clams.

Questions:

1. Besides Max E-260, what else will I need to get? RO system, refractometer, test kits... what else? Controllers? ATO? Do I need to purchase additional pumps/powerheads?
2. Reefer 250 I will need to buy lighting and protein skimmer correct? Do I need to purchase additional pumps/powerheads? Controllers? ATO?
3. Will two Red Sea ReefLED 90 suffice for keeping SPS?
4. Do I need to purchase additional pumps/powerheads?
5. Will the open tops be an issue? They look so slick. I was thinking clownfish x 2, royal gramma, banggai cardinal 1-2, maybe green chromis, nothing crazy. I know firefish and wrasses are out :'(
6. Will going on vacation for up to 2 weeks at a time be an issue? I plan to do this several times per year.

Will throw in additional questions as they pop into my head. Thanks!

FYI the reefer line is not an AIO. I personally am a big fan of innovative marine Nuvo AIO tanks but you will need a light with them
