Your 9lbs of LR

If you don't already have nano circulation pumps, then you will have to get preferably 2 pumps. Something like this: Hydor Koralia Nano Circulation Pump/Powerhead
Search online to see what nano pumps are available for you.
Terrance, you are awesome! My plan is to definitely buy more live rock, but I am waiting for a friend to buy about 80 pounds of live fiji rock as he will give me more. I don't want to buy more from my LFS
because their rock is not seasoned and is pretty ugly.
And I have about a 2-3 inch sand bed.
I didn't realize that I would not need a HOB
filter. I can get rid of that now, or do I need to wait until my tank has cycled awhile? What is recommended? I just ordered a filter/skimmer combo too. So did I just waste my money? Or, can I still use that and just try and find an alternative for my ATO switch/system? I do about a 2 gallon weekly water change also with RO
water. I also manually top off as needed with RO
I have one 240 GPH
powerhead in my tank. I am assuming that is what you were referring to when you said I needed circulation pumps? If not, let me know so I can look into that.
Thanks so much for your help and support. I appreciate it so so much.
