its easy enough to do but if your drilling the holes your self im not sure how easy it is to drill 6 holes in a 30" span?? could be easy as hell im not sure but worth checkin out.
also at 30" your glass would have to be on the thick side not sure if 12mm would do or not??
the 150 halides may not be as strong as you like if yu plan to keep any sps in there or high demanding corals...... depends on what yor keeping i guess
i just built my own cube and drilled it for a herbie style over flow and i gotta say these are ultra ultra quiet and no bubbles what so ever
much much better than a durso.
