Hello everyone, I am interested in getting into the saltwater live reef hobby. I’ve had a fresh water 10 gallon tank for 2 years and I think it’s time to make the next step. I’m looking at getting the Red Sea AIO MAX Nano 20 gallon tank, or possibly a 40 gallon tank and buy my filtration, and lights, etc. piece by piece. What do you think would be best for a beginner? Any advice is greatly appreciated.
