Not sure if any one else has trouble keeping the rocks in their tank clean. I just have a hard time keeping mine destrius free. I have decent amount of flow but still there are dead spot. Just replace one of the Jebao WP40 with Gyre XF130 still have one running on the opposite side of my tank and a return line to 120 gallon reef tank. Also, just wondering what every one is using to blow the debris off the rock when doing tank maintenance.
