I just dropped my 90 freshwater and started it up as saltwater. I'm hoping for gift certificates to the local fish store so I can buy some live rock to get it going right (instead of using rock out of my other tanks). Once that is set up and running good it is off to get a tang or rabbitfish and a bluethroated trigger to go with my puffer and snowflake that have patiently been waiting in their way to small tank to move in to their mansion.
Yea, I already feel bad about spending $100 on base rock (4 pcs!!!).
