Depends on what you want to do with your tank. Corals need light but on the other hand corals need LR
to sit on. If you can be satisified with a FOWLR
for a while till your light budget improves, fill it with rock. I would use a good amount of base rock to build the main structure (caves, arches, ledges, etc.) and a few choice pieces of high quality, well encrusted LR
to seed the rest. Intense lights will help this endeavor but you can only do what you can afford. A few months of this setup will help you get over the new tank syndrome of diatoms, algae blooms and cyano
. Shrimp and fish will give you something to look at While your LR
spreads to the others.
Good luck and have fun!
