Minimalistic multichip DIY LED build

The center tab is typically the wiper and the 2 outside tabs are the fixed endpoints. That is, there will be a fixed resistance between the two outside tabs and a variable resistance from the center tab to either outside tab.

Yes, but as resistance between the left and center increase, resistance between the right and center decrease, and visa versa. You want to wire it so that you get the expected results when you turn the knob. Right = brighter, Left = dimmer.

Could be magnetic feedback from that SPH-L710? (hint: Turn off the tapatalk advertisement, nobody cares what phone you are using).

You say "warmer than usual".... I am not sure any of us have a frame of reference to what "usual is". Also, under what circumstances is it "warmer". I am afraid you are going to need to provide a bit (maybe a lot) more context... and to that end, it may be best to start a thread in the DIY forum asking for help.

Same here, it hasn't been long enough to draw any conclusions, that said, I can definitely say my acropora frag has grown since the changeover. My montipora are not all that happy with the recent light increase - I currently have the caps shaded as they were bleaching. The monti australiensis seems to be happy with the increase as well. Last time I increased the light (with the old light) by a similar amount the green monti cap wasn't so happy but that coral has been sensitive from day 1.

My lights are on a 10 hour cycle with a ~3/4 hr ramp at each end.

After all the technical info it is time to check on whether the DreamChip is actually beneficial to corals.

I zeroed on my birdsnest from the beginning as it sits almost right under the light and is in the middle of the tank, easy to photograph right through the glass.

The first photo was made on November 11, the second one Today, meaning exactly two weeks later.





Birdsnest was sitting under T5 lights at my LFS so it needed some time to acclimate to the new DreamChip. This went fine, just as with the other corals. As you can see from the two photos there is a nice amount of growth seen after only two weeks and the coral looks happy.

I hope to be able to document growth of other corals as well and keep track of (hopefully) further progress with the DreamChip.
