OK, I put the new pump into the tank and have it running at about 1/3 speed on the W3 wavemaker program. It cycles from a dead stop to 1/3 speed (I get to control that top speed it goes up to) and back to dead stop over about 6-8 seconds. The 2 corals I have hanging by monofilament at the center brace are now 'dancing' and most of the soft corals are moving back and forth. The pump has a faint, low pitch whirring sound that I wouldn't notice if it where constant. But because it ramps up and down I can faintly hear it. But it's not nearly as loud as the big Reeflo pump on the closed loop system. It doesn't get any louder when I let it go to full power (4500gph) but it moves a ton of water. I'm going to leave it running like like this for awhile as kind of a break in. I also found that when I set the controller down and had the light sensor blocked by a power cord, the pump runs at about 25% to 35% of the speed it is set for and stops pulsing. So the light sensor works. I'll see tonight if the moonlights are bright enought to keep it running or are dim enough to allow it to go into night mode. Now I want to listen closer to an Eco Teck MP40 and listen for pump sounds. My guess is the Jebao makes a bit more noise, but it's not loud enough that Elaine has noticed and she can hear way better than I can. At this point I'm OK with a faint low pitch whir and $250-$350 in my pocket.
