Really... no apologies are needed. Glad to have ya!!! My best advice would br to purchase some good reads... try "The Conscientious Marine Aquarist" by Fenner and "Natural Reef Aquariums" by Tullock.

IMO, add all LR, now

Run skimmer

1-2 lbs is a good range of LR... depends if you intend to run a DSB(deep sand bed)

As long as you're circulating 10-20x's total tank volume, you should be fine. I do recommend a separate sump/refugium.

Your light should be adequatew for lower light softies which could be a theme reef tank.

Hope this helps!!! Take care and keep posting as things go on... Remember your best friend now is going to be a whole load of patience.
