nice build, the only thing I would have done different is bought spectral aluminum instead of polishing it my self. pollished aluminum while looking shiney only has a reflective index of 70 to 85% and will quickly corode again over the tank unless you put a lot of effort into keeping it shiney.

spectral aluminum has a reflective index of 92 to 99.7 depending on the quality and the reflective surface is actualy nickel which will not react with the salt air so it just takes a simple wipe once and a while to remove the salt creep.

any idea on the material cost difference between the two different aluminums?

well, 8 years ago or longer.. I did a buy of a full sheet of it 4' x 10' and it cost me about 200 bucks. that was the only way I could get it on the island and there were several others that wanted to build there own reflectors so it worked out ok. only had about 4 sq ft left over and who knows where that went to.

seeing as your in vancouver you should be able to get it in smaller sizes and cheeper, check with sheet metal places and such..

I will keep that in mind for my next build (when I have money to spend)

I found this product at the bottom of the page, the 12" by 24" @ US$14 would have worked for me. I think that is about 4x the price of what I used, but since i already had it the cost difference would be US$14
