Any pictures of your tank with the streams?
About the sand - i am concerned that even though it may settle... it may settle in a way that doesn't look right ;/
For cheaper than adding a stream, I could have 3 maxijets on a wavemaker... however, I am willing to get the stream if it really does push current in areas of the tank that the maxi jets wouldn't. Do the Streams actually blow downward and even behind themselves?
Another concern is that I have an acrylic tank with nearly a 4 in. lip on the top of it. I really wouldn't want the TS sitting that far off the wall of the tank - hovering .. ugly. I saw a mounting kit that puts it back against the tank wall, but will one of those work with a 4 in. lip?
Thanks!
