Yep, the dart is running wide open! I thought it would be too much, but it's not. I'm planning on doing a mod to the overflow this weekend, I can't remember the name for it, but it's the one where you use a single drain that is submerged under the water by a few inches, and you have another emergency drain so to speak in case the primary ever clogs. This will eliminate what little micro bubbles I have at the moment.
Considering the rating on the pump I was expecting to get major flow in the tank, which I do, but it's not toppling anything over. It's actually been very nice not to have to look at power heads, etc...
