When looking into the acrylic, did you manage to find some that doesn't pull out some of the light's spectrum? When attempting to make lids for my tank I ran into this issue and ended up scrapping the project. $200 worth of acrylic lying around now

Are you planning to put any bracing in for the acrylic? That stuff likes to bow like crazy in higher humidity and temp.

I haven't looked for the acrylic yet but will be stopping at Sabic next time I go to Calgary. I am going to use 1/8" or thinner & will be held in place on all 4 sides by the frame of the heat sink.

I would guess it around 50 lbs each, but I will have to actually calculate the weight.

Just out of curiousity, but why are you using red and green LED's? Red shouldn't only be used if you are growing plants. Not too sure why you would want green either...

I built my own DIY LED fixtures, I should probably make a thread too. I wish I knew how to weld, and made my own heat sinks.... I am jealose of your heatsink! The cheapest I could find was still expensive and not custom to my tank (heatsinksusa.com just in case anyone was curious.

Heres's the piles of LED stuff, LED's, optics, connector, fans & power supplies, 1 EVG Profiilux controll board, adhesive and what nots.



Drivers, 5 - 120w, 2 - 75w & 2 - 38w (still need to pick-up from Martin)

Looking good so far.

Are you at all concerned that a slight warpage in the base plate will cause an airgap and render that portion of the sink less effective than those next to the welds?
