I just got 2 250's yesterday for my 90 and they are super powerful. I'm still trying to learn the settings but I currently have them on the "circular"mode. Not sure what the name is for it but it's basically on for 1 second where it blows on the top and then it blows on the bottom. The second pump does that same but in reverse. This way the water column spins top to bottom and back around.

Yea i had a number of people recommend that i get 2x 230's for my DSA 105.One 230 at 50% blows the 12 anemones and LPS around pretty good.You probably would be better off with 2x 230's.Thanks, I think I went a bit overboard with my 2 250s for my 90gal. It's way too powerful. The max I can keep the pumps is 10% and if I even try for 20% everything gets blown around and the fish go crazy. Wish we were able to step a % at a time instead of 10 unit increments.
Can these be run without the advanced controller?
