I have drilled my sump using patience and a very cheap system. I purchased a standard set of holesaw drills from mitre 10 ($6) and a $7.50 pottle of valve grinding paste from Repco. I selected the size of drill and mounted in my hand held drill (no fancy drill press). To keep things lined up I drilled a hole through a piece of 25mm pine and then clamped it to the glass with another piece on the reverse side. The hole in the wood was lined up on the glass. The tank was positioned on its end so the working surface was on the top. The hole in the wood acted as a well for the grinding paste and keeps the drill lined up. I set the drill to reverse and about 30 mins later I had a very smooth edged hole in the glass. The teeth on the holesaw were ground down about 50% and would easily cut more holes as the metal acts as a medium for the grinding paste to do its work. PM if you want details. I found this much cheaper than purchasing diamond drills for one hole. Different if you were drilling lots of holes. Cheers

Hi Fay I like your streams - I have some as well - Have you set them up in the corners? and have you programmed them with a controller? Thanks Chris

Pies - a bit more notice mate! Hope it went well.

Thanks how it looked to me. Thanks.

Thanks for the offer RnB, I won't ask how. My kids want a 'nemo' so not sure if these are the right ones.
