So i have an older powerhead that just won't stick to the tank anymore. I'm looking to replace the old suction cups with magnets to fix this problem. I've read somewhere (may have been in this forum) that DIY'ing an epoxy coated neodymium magnet to replace the suction cup works great, but i was wondering if anyone knows of a product that is specifically for replacing them old suction cups with magnets? I don't mind DIY'ing a magnet unto my powerhead but if there's a plug and play replacement out there then that would be a lot better
