for a 3x6 table i would advise getting at the least a 50 gallon res.. 70 would be ideal, and any larger would be best..
when thinking about your res, you have to understand that the bigger the res you have, the more ppm and ph stability that you have, which means your plants will be healthier and happier, not to mention less res changes and fluctuations.
and depending on your medium you can go with a few different pump sizes.. larger pumps would be more for hydroton so that it fills and drains quickly, since your feeding times would be close together, and if you are using something like coco or rockwool that holds a large amount of water, you dont need a large pump because you will only be feeding a few times a day
hope this helps

I get away with a 40g rez for my 3x6 & 4x4 tables....
I am adding about 5g of water to top them off every other day, but in doing do I am constantly checking PH & PPM so its a good "work" so to speak by keeping me involved a little bit more than if I just "set it and forget it".
The more plants/bulk you have on the table the less water you will need to reach the overflow point.... I usually have 20 plants on each table, in 8" mesh pots.
good luck

You haven't told us two important details.
The depth of the table to figure out the exact cubic volume of the table and the height of the containers you would like to use.
Volume = Length X Width X Height
Gallons = Volume X 0.00433
i.e. 76*40*7*0.00433 = Total of 92 gallons
i.e. 76*40*5*0.00433 = Total of 66 gallons
Remember two goals
1. you want to fill 50%-75% of the container
2. you should keep an extra 10-15% extra water than needed during your flood.
Good luck. Hope this helps.

how many times a day should you feed using hydroton?

Yes you could get by with a lower gph pump, you would just have to flood longer.
