It is always recommended to create a drip-loop when using any electrical appliance in an aquarium. Do not use in a container smaller than recommended.
Top Customer Reviews
1) Inexpensive and stupid simple to install
2) Works well in 3 gallon volume of water
1) "Always On": it does not have on/off when it hits a certain temperature thus it will keep raising temperature in a small volume of water. ***BECAUSE OF THIS YOU NEED TO MONITOR YOUR TEMPS CLOSELY, ESPECIALLY IN WARM ROOM and/or SUMMER!!!***
2) DO NOT recommend this heater for anything smaller than 3 gallons, see notes.
3) Even with gravel on top and lots of power cord slack, this heater has a tendency to want to "float" up to about the gravel line no matter how deep I put it under the gravel (have about 3/4 inch gravel on top).
BOTTOM LINE: Solid BUY if for 3-5gallons of water. If you are looking for a Betta tank heater for this volume of water, this is the one to get.
Bought this to initially heat a 1.5gallon tetra aquarium (see review) Tetra 29137 WaterWonders Aquarium Cube, 1.5 Gallons, Blackand it would raise the temp too high for Betta(upto 87F in a room that is about 75F). Moved the fish and this heater to 3gallon tetra tank Tetra Cube Aquarium Kit, 3-Gallon and temps ranged from 77-81F throughout the day. Not sure if that's too "wild" of a temperature sway in 24 hours but my Betta does not seem worse for wear or stressed. Will update this review if something changes.
Update (5 days later): I removed the heater immediately after I noticed my Betta was burned (about 3 days after I got the heater.) At first I took my Betta to the local exotic fish and reptile store so they could tell me what happened to the fish and how to help it. They said that the Betta appeared to have been burned by the heater and informed me that they've seen this before. Apparently this frequently happens when people purchase a cheap heater over the internet. The store employees then recommended a product called Melafix by a company called API. They told me it was a 7 day treatment and could help regrow his burnt fins while preventing infection. However, 5 days later my Betta passed away from its wounds. I'm really sad about it. I hope this story prevents this from happening to a future Betta owner.

I bought 3 of these, one for each 3 gallon tank. All 3 of them barely felt warm to the touch after plugging in. Completely useless. I do not recommend.Published 17 days ago by trekkergal
