I talked to a lfs they said they sell premixed SW for $1.99 or something like that a gallon all I need is 3 gallons. So I would need live sand but they sell it for $16 a small bag but i think that's a rip off. They said they sell live rock too that I would only need $5 worth. I don't think that I would need to upgrade my light because it's perfect for coral. Somebody said i might need a ATO because of humidity. I'm sure that I could make one. What you think? I'm thinking a neon goby would be perfect for this tank.
