That sounds like you have more than enough air for your rezs.... Your rezes do not not need to roll like a hot tub. Just a steady stream of small bubbles is all you really need....

For a small setup of just two tubs you can get away with just using a large aquarium air pump and 2 12 inch stones for each tub.
