Newbie advise needed... Diary of a new tank junkie

[ensquire]

What exactly would one use to cut the tank? I went over your thread Smallfry and am a little unsure. Was it a dremel product diamond wheel? Checked the local box stores yesterday and could not find anything that resembles a diamond cutting wheel. Had to order all my fittings online cause noone in Yellowknife handles PVC to any degree,
This is gonna take forever.
