Exactly what I wanted. The the suction cups that came with my BRS 600 Watt Titanium Heaters were completely useless. These magnets are perfect. No issues whatsoever with holding the heaters firmly in place in my Waterbox sump. (8mm or 5/16”) glass.

Anyone that has kept fish for any length of time has no doubt had this issue: new heaters with their suction cups work great for awhile…then lose their ability to hold & fall off constantly leaving your heater resting wherever it falls. These eliminate that frustration! I’ve used these on glass as well as very thick acrylic ( The 300 gallon tank in the photo ) & they work great. They’re very sturdy & well builds & should hold up for longer than those rubber suction cups. I’ll update with time but very impressed so far.

Ok ok ….. it’s 39 bucks for an aquarium heater holder or get two for $70 dollars . Well … I have to admit …… it was well , worth the money. I’ve had many aquariums over the decades …… and it’s the same problem . After a short time your aquarium ” heater ” starts hanging loose or at a weird angle .Those ” suction cup holders ” just doesn’t do it’s job ……but these “magnetic holder ” is it !!!!! Finally every time you go look at your aquarium , the heater is exactly where you left it ……..NO MOVEMENT of any kind . Well spent money .
