Super easy to drill.
Go at a pretty slow speed and moderate pressure to keep the acrylic from melting.
Watch the other side of the tank, and note how far you're in the tank by looking at how far the pilot bit is sticking out.
When the hole saw is almost through, increase the drill speed, and put very little pressure on the holesaw, this will prevent the tank from cracking a little bit and "blowing out" on the inside of the hole.
I drilled 5 holes in my tank with a regular hole-saw from home depot. Was not hard, but take your time and don't rush it.
