Been using for few years Review: Beware! Glass Broke while in Tank! - I received my heater on the 20th and it was in good condition and worked great. It kept the water temperature at a set 78degrees....BUT TODAY....only 6 days later, when I was doing my 50% water change, I came to find out that the glass had popped! Fortunately non of the glass had broken off while inside of the tank. Only once I removed it, did it finally fall apart. I a very disappointed that this happened and my husband and I do not understand why it happened. It was placed by the filter so that a constant flow of water would move pass it as recommended. So what would cause it to pop. In my opinion, it is really unsafe for aquariums. ****UPDATE**** Two days after posting my review I was contacted by the Mylivell seller though email to rectify the problem. I am highly satisfied with their costumer service and professionalism. They were very sincere and prompt in their replies. As of right now, I have the new heater in our 36gal. It has been six days since the setup of our new tank and the heater appears to be doing fine. Just as the previous heater did, this one is also keeping the water at the set temperature. My husband and I genuinely hope that the popping of the glass tube on the previous heater was just an isolated event and will not happen again. But If another issue should occur I will be sure to post an update.1/17/20 ## Features - Mylivell 200W aquarium heater, length 11 inch, voltage 110-120V, power cord is 4.2ft, suitable for 40-65 gallon fish betta tank and turtle tanks and other small fish tanks or fish bowl, can be used in seawater and freshwater. - 【Easy to Set Temperature】: With the aquarium heater, adjusting the water temperature is a breeze.

It shows the coiling inside of the heater which gives a cool industrial appearance. That’s as far as I got though. The glass feels thin when holding it, a bit thicker than a light bulb but not a lot, at least not compare to other heaters that I’ve had. Anyways, as I was setting it up in the tank, I set it down too quickly and it cracked in half leaving shards of glass in the carpet. Thankfully it wasn’t in the tank when it broke as I can’t imagine replacing all the gravel in a 75 gallon tank on Christmas Eve.. Either way, if you’re willing to risk it, it looks cool and has decent instructions --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/158554332-fish-tank-aquarium-heater-adjustable-submersible-200w-aquarium-heater-thermostat](https://www.desertcart.tn/products/158554332-fish-tank-aquarium-heater-adjustable-submersible-200w-aquarium-heater-thermostat) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-29*
