https://www.saltwaterfish.com/vb/showthread.php?t=264597 You can skip the first section about how to post, you already know that. Start with the beginning your tank section and read, read and read. Your brain will hurt, your nose may bleed, you will see stuff that you already know, and you will see stuff that you did not know, and did not know to ask about, Once you fel woozy, you will be fine. We all have done it and felt it.
In answer to your questions, and RO unit is a reverse Osmosis unit and is really a superfilter for your water. They run about $150. You can also buy RO water at your lfs or in jugs at the grocery store.
Agree 1000%, we are not trying to offend, but some basic knowledge is needed here. Buy a book or two on keeping SW tanks. Three good ones to consider may be "Conscientious Marine Aquarist " , "Marine Aquarium Handbook " and "The Essential Guide to Keeping Saltwater Fish ". These materials are very helpful to those new to the hobby and nice to have for reference, even for the seasoned vets out there. Just my 2 cents
