Octo Strong Heater Holder

(1 customer review)


Don’t fall for wimpy magnets!  I revolutionized the usage of high-powered magnets in our industry!



Let’s face it….suction cups, well, suck! And then they pop off. That’s why my products feature super strong neodymium magnets. One thing that always bothered me about heaters is that they come with suctions cups that eventually stop doing their job. Well, now you don’t have to worry about that. These Octo Strong Heater Holders™ are made from 1/4″ clear cell cast acrylic, will hold on glass up to 3/8″ thick and feature o-rings made of a material that can withstand the elements of a saltwater tank. Available in both single and double configurations, for standard round heaters (up to 1″) as well as the flat Cobalt Neo-Therm heaters.

(Heaters not included)

I use N52 neodymium magnets. Rare earth magnets are not reef safe on their own, so I fabricate custom acrylic pods that encapsulate the magnets and keep them away from your water. Please visit the magnet warning page for more information on these magnets.


My products are made to order, custom! Please allow up to 10 business days for fabrication time for most products. Because my products are made to order, fulfillment time can rarely take longer. Full custom orders can take up to four weeks to complete. Please let me know ahead of time if this may be an issue. Shipping prices listed are to the contiguous U.S. Please contact me if you live elsewhere and want a shipping quote. Because my products are handmade and/or hand assembled, there may be small irregularities which will not effect the performance of your product.

    So far so good!! These magnetics are CRAZY STRONG!!!! I purchased 2 of these holders to use with 300w Titanium heaters and so far I’m very pleased with them. I was sick and tired of suction cups moving around & “un-suctioning” during tank cleaning time – not an issue anymore! Thank you!
