I have 4 6100's, 2 on each end of the tank. The tank dimensions are 96"L x 24"D x 31" tall, total volume 240g. Could I get rid of 2 of the streams and add a wavebox for more desirable flow? Or keep all the streams and add the wavebox also? Lastly I could just do nothing and keep on going as is but want to benefit from the waves.
