My biggest regret is not drilling my tank when I had it all broken down in early November. Since I am still without fish/coral, I am considering partially draining it and drilling it. I would like to drain most of the water, leaving a few inches in the bottom for my CUC.
Can I drill this while the tank is upright? If I drill it from inside the tank, can I run the output from a small pump to the hole saw for lubrication?
I'm in Vienna. Is there anybody close by that has done this before? Would you consider helping me out with this?
