thought i would ask this because i recently got a kanger aerotank and a nautilus tank. before that i was using my trusty old protank 1 with the airflow holes drilled larger. then i got the new tanks and the draw seems too tight for me. eventually drilled the one aerotank hole bigger last night and now it seems ok for the moment. still not liking the airflow on the nautilus. could also be because my little dripper has a lot of holes now and the airflow is beeg very beeg. thoughts?
