Yeah, that's why I labored for 2 hours digging that hole and leveling it haha. It was a chore, for sure, but at least I know that the temps won't fluctuate as much, like you said.
And yeah, they are sedums. That name sounds familiar, and a quick google search shows that you are right.
I'm pretty pumped about this powerhead. More than I should be, considering it's a powerhead, but the thought of a dual propeller pump that pushes 3250 GPH in a 100 gallon tank just sounds like too much fun
Good thing they ship priority.
