Looking for Autotop off / Cleaning magnet

[HaZRaTTy]

Hey,

I thought I would post here before I go out and buy new to save a few bucks that I could be spending on ''better'' things for the tank cough inhabitants.

Would like a Tunze Auto top off, but open to other brands.

If you have a magnet along with an auto top off even better. I will be ordering them by the end of the week (Sunday)
