The local Petsmart's here still have a printed recall notice by the fish filters and will accept any of the recalled heaters. Here's the recall notice, you may be able to print it out and take it in to make it easier.

Dear Valued PetSmart Pet Parent,
Marineland has issued a voluntary withdrawal of the Stealth PRO Submersible Heater (100, 200 and 250 watt). The product is being withdrawn due to a quality issue.
If you have this product, please stop using it immediately and take the following steps:
1. Unplug the heater from the wall to stop the flow of electricity
2. Let the heater cool for 15 minutes
3. Remove the heater from the tank
Please bring the product to your closest PetSmart for a full refund or exchange. Replace the product with a comparable heater as soon as possible to maintain the temperature of your aquarium. A PetSmart store associate can help you select the right heater for your aquatic environment.
If you have questions about this withdrawal, please call Marineland Customer Service at 800-526-0650 or 800-432-6986.
At PetSmart, we are concerned pet parents, too. We will continue to do everything we can to help you and your pet during this time.
Sincerely,
Debbie Gonzalez
Vice President, Brand and Customer Marketing"
