You should be OK at that rate. I use a tiny air pump with mine since my venturi is rather small and not the best in the world tbh. The venturi action isn't really enough to suck through the air dryer and ozone unit. Bubble production stank until I added the airpump.
Just remember, if you start smelling Ozone in the air, it might be a good idea to backoff a little bit
