I have two streams and a wavebox for my 160G tank. The tank is roughly 60" long and 25" high. I have the two streams in the front corners pointing to the opposite back corners and the wavebox on the right side. The wavebox is generating a 1.5" wave and I have the streams set to interval 2. My rock formation is two peaks with one on each side of the middle overflow. The problem I am having is large dead spots behind my rock formation on both the left and right sides. I was thinking of adding in my spare Turbelle electronic pump but not sure what is the best formation and setting to get my maximum water movement.
