I'm going to take it nice and slow, I made a few mistakes with my tropical so I want to learn as much as I can before the tank is ready.
No filter for a reef. It's your live rock. You need 1-2 lbs per gallon, or for your tank (abt 40 gallons US?) you need 40-80 lbs, or 18 kilos to 36 kilos. 15 is a little shy of that, but if you can find lacey limestone, that would condition into good rock. Your live sand will help.
Problem is, if you put dry limestone is, you're going to leach phosphate out of the rock, which will fuel a lot of nasty hair algae---the good news is you can stop that with a gfo (granulated ferric oxide) reactor, which sops up phosphate. It's always a trade-off in marine---everything affects everything. Read that red arrow sticky up above.
Plan, plan, plan. Are you going fish only, corals- what kind? Have a plan and research species comparability. Know your budget for equipment and plan accordingly. Check out sellers forum for good deals.
Most importantly IMO- have a QT and make sure you use it. Research quarantine procedures.
Above all don't rush things- it will cause you a lot of pain and cost you a lot of money.
Below is a good comparability chart.
Welcome and good luck- don't be afraid to ask questions. If you research and plan you will be experiencing an amazing hobby.

Take everything you know about freshwater, and forget it. Saltwater is a whole different beast. About the only thing thats the same is the nitrogen cycle. Different bacteria, but the process of cycling a tank is roughly the same.
