I was looking at doing this for my 37g Saltwater tank. After finding a bunch of write ups & videos I found that it didn't seem very cost effective for me. But you do have the least expensive cost on supplies I have seen so far. Some were making them with $400 worth of supplies when you can buy one for $500. Didn't seem worth the headache of finding and buying each piece and getting the best deal on each piece and then learning how to put it together. You have made me think again on attempting this. I will follow your results.
