What is the ratio of sump to tank I should look at. Is it just a matter of being able to get my equipment in it or is there a calculation based on tank size?

there probably is a calculation but I've always thought of a sump as a good hiding place for all the equipment you don't want in your tank, so if you can fit it all in there and still have some nice flow, you're good to go. Also don't forget to think about water changes and your system volume (at least thats what I thought of ie. how much salt to do a 20% weekly water change) it can get pricey with a larger system volume when its not all display tank.
