Hey, nice work on drilling the holes, I know I would have been nervous as well. I know gl[censored][censored][censored][censored][censored][censored][censored]s dot com sell the drilling kits which people use for drilling the reef tanks, which comes with some putty to put around the hole so you can put water near the hole your drilling and it is contained there until the hole is made obviously. I am looking forward to seeing more pics on this build. Oh and whatever you do, do not use the Power Sand stuff from ADA. It is so annoying and I can't get rid of it in my tank. Good luck.
P.S. If and only if you have the extra cash flow in hand I would shoot for the ADA Solar light. I would more uniform with the tank you have.
