Good lord. I tried the larger propeller first on my Maxi 1200, and there was a literally an underwater tornado in my 50g tank. The water flow was excellent, but the fish didn't seem happy all plastered to the far end of the tank, and sand was flying everywhere. So, I put the smaller propeller back in, and positioned the powerhead high up and it's doing great. It's kinda noisy, but I'm hoping it will get quieter as it breaks in.
