Thanks for clearing up that for me, much love to all of you guys.
I've used a similar sized pump for a 5gallon dwc, but I would recommend upgrading to bigger pump for that size container, or maybe even two pumps. In my knowledge, it seems that the more tiny bubbles, the more your plant will feel fine.
