well i am ready to make the switch from fw to sw in my 10 gallon. I calculated teh cost of switching at around 50$. Just tell me if i missed anything and dont worry i researched and i have a friend who can help me out if need be. I plan on getting like 12-13 pounds of base rock and then seeding it with A couple pounds of live rock. I am gonna get play sand and seed it with sand from my friends 40 reef and he trades with evry one so it should be pretty diverse. I Am getting salt mix and the occupants will be a clownfish and either a clown goby or this cool psuedo chromis i saw at my LFS
