Hello, everyone. I've posted in the freshwater section a few times and our freshwater 76 gallon is doing well now. I have a chance to get a 75 gallon that's set up for saltwater tomorrow. It comes with lights (not sure what kind), stand, and the sump? that sits under the tank in the stand. No rocks or substrate, as that was taken out. I'll post a picture of it with this post. What do I need to get in order to get the tank ready for fish? Any advice would be greatly appreciated. Thanks.
