I have to chime in on the wavemaker , I have one in my 380 along with 2 6200's . I have the 2 6200's on one end and the wavemaker on the other. Talk about rocking ! I think that lighting was the first priorty on my tank, And the Tunze were behind only by a hair. And I mean a thin peachfuzz hair. There is nothing more important in my opinion. The lighting and this major flow have made more of a difference with my reef than everything else combined
