Grizz's 300 gal 8'er / LED Heat sink build / Opinions on LED lay out needed

[The Grizz]

External for now on the 165 gal. I wanted to see how they preformed so I ordered 3 of the 10000 so I could put one on my existing tank to gauge the flow and noise level of the pump. Now that you mention it there is a slight whinny noise coming from the pump but I have to shut off my closed loop pump & my skimmer to really hear it, after all compared to what we have lived with for awhile now with load pumps I can live with a little whine.

Also noticed that the pump does put out a little heat & I don't want to put that heat into my water column so I will be running them externally.

The new stand/cabinet for the 300+ gal tank is going to be as sound proof as possible inside to keep it as quite as possible.
