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?

Sorry Cheryl, Missed the question,
I am sure that there is some equation for this. But my opinion is that what ever you can accommodate under your tank that fits all your equipment. LOL
If its an external sump then really there is no limit up too actually DT size.

Any new updates ???
