I just recently converted my 30 gallon brackish tank over to full saltwater with a specific gravity of .20. The tank still has freshwater gravel, and 3 pieces of mopani driftwood in it. My tank houses 4 spotted green puffers that get along great, i got them out of a tank that had about 35 GSP's in it so they arent aggressive at all. my question is what to i do next?

do i:

a.) transfer the puffers to a bucket and proceed to take the freshwater gravel out of the tank and replace it with crushed coral. and get some live rock while im at it.

or

B.) Do i just ante up 125 dollars and upgrade to a 45 gallon tank that will fit my stand perfectly and start from scratch. because i have heard that getting gravel out of a tank without scratching it is very difficult.

I would go with a. I would also raise your SG to around 1.025 if you want to keep corals. I've heard and read bad reviews over crush coral. I would get sand instead. Take out the driftwood. Will your puffers have a tank to stay in if you take them out of the tank?

I would go with option B. Bigger is better. Sand is better.
