I have had a lot of fresh water tanks and have not messed with any salt water for a few years now. Im planning on getting a 180g tank and plan on doing a fowlr. Im a fan of the triggers and puffers and angles. Im trying to get a ideah of how much live rock and sand im gonna need. I also plan on getting a rr tank so that i can have a sump. Any suggestions on equipment and fish would be greatly appreciated.
