I know this question has come up before, but I can't find the threads. What mods do I need to make to get the Tunze 9002 to fit into my first chamber? I just got a used one and haven't fit it in yet. If I have to cut a lot, I may just skip it and buy the Sapphire I originally wanted however since I have it, I want to give it a go. Any details would be greatly appreciated. Thanks

You need to remove the magnet so it can attach to the tank wall. Also, you need a new collection cup from StevieT to make it fit. I think the site is mediabaskets.com

That is correct. The magnet is pretty easy to cut and remove. You can use a razor blade and score the ring that holds it or use a hacksaw blade. It is not glued on just held on by a ring.
