I tried the eggcrate in the sump. Still not quiet. I'm beginning to believe I'll just have to adjust to it. Actually, it's still quieter than the previous system that was running so I guess I shouldn't complain.
I just HAD to get an idea of how this was going to look so I tossed a set of PC lights on it. This is only 4 x 65 watt bulbs.
And a surface shot showing movement from the OM 4-way.
