Had the pump for a long while now. Thought when I set up a new tank it would be bigger than a 20g, but a 20g is what I went with. I'll mess with it this weekend and let you guys know how it goes. I have a feeling its going to be too strong for a mixed reef.
kris, i'm pretty sure the 6045 is going to be a bit much for the 20. sell it and get 2x koralia 2's...they are under $30 new. better yet add a bit more money and get an mp10.....takes up less room, fully adjustable, wave modes, can get battery back up. i think the old model mp10 goes for less than 170.
