Will a 50 Watt overheat a 6.6 gallon tank?

No, it should be fine. These heaters have an adjustable settings. I have a 300 watt for my 90 gallon fish pond and have it set at 80 degrees. It kept the water warm and prevented it from freezing during the winter.

I had this heater in my 6.6 Petco Bookshelf aquarium with my beta for well over a year and it worked just fine.

No. I have 2 5.5 gallon tanks and it does not overheat. It turns off automatically.

Depending on the size of the tank I I would say yes if its larger then a 50 gallon. If 50 50 gallon or smaller just put it in the middle.

I have mine running in a 49 gallon tank with 15 gallon sump cooling to 70 degrees. It cycles on about half of the time when the room temp goes above 70. I'd imagine it would need to run a lot more to cool to 65. Might make sense to go with the 1/6.

It will probably over heat it. There is no automatic turn off. Its made for a larger tank then that

The 50w model was designed for 6.6-15.8g aquariums. The full list of their heaters is listed here: https://www.eheim.com/resources/product//450/downloads/11/EHEIM_aquarium_heater_25_-_300_manual.pdf

I have a 20 gallon aquarium also and I have a 100 watt but you could probably get away with a 50 watt. I always set the heaters up vertical so really couldn't tell you on that

I don't know if that is answerable. Would depend on ambient temp and other factors. My guess is 1 or 2 feet max though. The aquarium heater I have in a 40 gallon tank is only 40 watts and it cycles on and off and can raise the temp 20 degrees above ambient I think without being on all the time. So for just 2.5 gallons I wouldn't think you would need very much @ 20 watts per foot.

Hello RaeRae, You answer is not so simple. The capacity of a heater not only depends on the heater itself, but the original temperature of the medium. Even though this is rated for a larger tank than you are asking about, if the place the tank will be in much colder than average is may be a good choice. If your water starts at 65 degrees, and you want it at 78, this may work for you. If you start at 72, this may get the water hotter than you want. Another aspect to consider is how much water movement you have in your tank. The more water movement, the better the heat will be distributed, and the water will be closer to the thermo's temp setting. I agree with JR, I have not seen any for that small of a size. You could look at reptile heating accessories that afix to the outside of the tank, it would be a hack though.

I got the 300 watt for my 55 gal. seems to do fine. I rather have a higher watt and turn it down lower. Besides after they get old and don't work as well a higher watt seems to do better. I think a 250 would do the job for a 55 gal

No, probably not in the sense you mean. This is an eight watt "always on" type of heater, it has no thermostat. The heater will continue to emit eight watts worth of heat whenever it is plugged in. With very few exceptions all small "bowl" or "betta" heaters work this way, the only difference is the wattage. They are available in 5 to 15 watts, you need to match tank size, ambient temperature, and other variables to heater wattage. A thermometer and monitoring is essential, especially at first to determine what temperature a particular heater keeps a particular tank, and if room temperature rises so will the water temperature. The term "preset" is not really applicable to these heaters, preset heaters have a thermostat that is permanently set at a certain temperature. If a heater description uses the term preset without stating a specific temperature (usually 78) then it is NOT a thermostatic heater- it is an always on type. In too small of a tank or too warm a room these can overheat the water. Bettas are very heat tolerant, which is why using these heaters is feasible, but care is still needed. In anything under 3 gallons I think eight watts may be more than needed unless in a fairly cool room.

50 extra watts as long as you vent your cool tube correctly wont make much of a heat difference at all.

A 150 watt heater should suffice for this size of tank if you are going to keep tropical fish not cool water varieties (such as goldfish). The main thing to remember is to keep a constant temperature and water conditions. I listed below a few good websites for beginners. My advice is to do a lot of research on the fish you want to keep and set the tank up appropriately to the types you want to have. Also remember to cycle your tank before adding any fish and after the tank is up and running do regular water changes and tank maintenance.

Possibly so I have a 300 watt and I have to turn the temperature down below what is recommended for my Oscar's in a125 gallon tank Or there could be something wrong with your heater :-)

Not a problem... I'm using mine in a 6 gallon acrylic tank and I'm very happy with it. Keeps the tank at 75 in a 60 degree room through the winter. I would recommend this heater you wont be sorry.

For a 150 gallon tank. I am assuming that it is fresh water, but either way, I would purchase 2 - 300 watt eheims. If you have returns, I would place one in each. The reason why two is for redundancy if one fails. I have two setup on an Apex system and can keep the temperature constant at +-2 degrees. Also if you have to elevate the temperature of the tank to cure something like ich, having the two heaters will ensure you can take the temperature up.

Yes you can. To save money you should find one that is made for 5 gallons or smaller. Basically you're paying for the size. If you get one made for 200 gallons you can use it too, it'll just heat up to its degree you set, (78-82F is ideal). But if you got a 5 gal one and tried to warm a 200 gal one it won't work because the power is too low and too small. So yes you can use this but for cost find something made for a 5-7gal.

Hello. I wanted to start by noting the heater I received is not the one in the picture. It is shorter and thicker, and only has one suction cup at the top.That said, I bought this one because it was the lowest wattage I could find for my 1 gallon tank. The recommendations I found said 7 watts for 1.5 gallons and up, 5 watts for 1 gallon and up. I have not seen any for smaller tanks than that.
