hey guys a I bought a 125g acyrclic AIO tank and I want to remove the acrylic bio balls area in the back overflow area so I’m able to put a nano protein skimmer on each side. I can’t get a circular saw or jigsaw in the 4-5” opening and I can’t get the angle needed for the Dremel with a disc bit. I was thinking of either using a sawzall and go slow while spraying cold water on it from a squirt bottle, use an oscillating tool, or using a hand saw. What do you recommend as my best solution? Here’s some pics to help you visualize it.
