Planning 20G reef

[tlittle]

Hello all, I have been out of the hobby for a couple of years. My last tank was bigger than I want to go this time around.....It was a 55g drilled tank, that I had on the first floor of our house. I had plumbed the tank to the basement where I had another 55g tank set up with carbon/skimmer/ and refugium. This time I am going a little smaller 20g acrylic tank with a sump under cabinet set-up. The sump is 15g, my question....should I add another reservoir in the cabinet to increase the total volume to say...45gallons or just go with the tank/sump? Oh, I am going to focus primarily on soft coral (mushrooms, anemones, leathers) maybe one clown fish.

hello all, I just got my tank and sump in today......two questions: one, how do I post pics? two: I currently have one hole in tank for return water.....it is on one side of tank....should I put another hole on the other side and split my return to send it to both sides or do I create a pvc pipe that sends some of the water to the other side using the one return hole? or should I not worry about it and put a power head on the other side and just circulate the water around the tank? It probably would be easier if I had pics to look at.
