I am having a bit of trouble getting my wave box adjusted, presently I am getting about a one inch wave but have room for another half an inch( is one inch enough?), getting sea sick now watching the tank, and still the best investment lol I have made for moving water, but my adjustment is set at the minimum level, and as I increase the dial, I seem to lose the wave, should I possibly be going higher yet, will it then start breaking another wave or I guess once the wave starts thats where you leave it? The tank is a 6' x 2'x2'.
