Question on air domes and pump

I’ve been growing in the fabric 3.9 gallon pots, loving what they can produce, and thinking of getting air domes. I have an aquarium pump with 2 ports. It’s rated for 40-100 gallon tank. Would that be enough for 2 air domes?

I’ve read all good reviews about the domes, hoping they’ll prove they’re worth it.

Do I need a different pump?
