Air Pump Size

Im wanting to do 10 plants in 5 gallon buckets. How many liters per minute should my pump be to produce the maximum amount of bubbles in 10 five gallon buckets. And also would it be better to have individual buckets or have 2 large reservoirs with 5 plants in each

I use an 80 watt commercial pump with a 12 way manifold. That would give you 1 stone per bucket and 2 in the reservoir. I would individual buckets connected to each other.
