<p>Google is your friend here. Try typing "300 gallons to cubic feet" in a Google search bar. It'll respond with about 40 cubic feet or 69120 cubic inches. What shape do you want the tank? I hear that round is the ideal shape for high-density fish populations. So, volume = height * pi * radius^2. If you assume a height of say 3 feet (36 inches), then the radius is sqrt(volume / (height * pi)), or sqrt(69120 / (36 * pi)), which is about 24 inches, or two feet. Thus the tank can be 4 foot…</p>

Thus the tank can be 4 foot diameter and 3 feet height to give roughly 300 gallons.</p>
<p>A 100 gallon grow bed is about 13 cubic feet. This need to be probably 1 ft deep and 4 foot wide. Any wider and it gets hard to reach the plants. Some people prefer 2 or 3 foot wide grow beds, but that is up to you. At 1 ft deep and 4 feet wide, that makes for a length of volume / (width * depth), or 13 cubic feet / (4ft * 1ft) which is about 40 inches, or 3 ft and 4 inches. You will want at least 1 ft between grow beds; this is what I do in my garden. However, to be comfortable 2 feet can be really nice if you have the room. I would probably go with two 10 ft long rows for the grow beds with 2 foot path between them.</p>
<p>You have plenty of room for all of this on the 13x20 concrete pad. You may want to scale up a bit and grow more vegetables given the space you have available. </p>
