30 gallon tank. It has been set up for a week. The heater is set to 80. I can't get the temp above 76 in the tank. Should I consider the 200W heater?

I have a 30 gallon nano and use the 300 watt version, I think I could have gone with the 200 because I have to keep the temp setting around 74 to keep it around 80 degrees....so it definitely runs hot

If the heater isn't placed by your filter outflow, it won't heat properly. So if it's not, try that. I do always go one above recommendation though.

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 :-)

I wouldn't recommend it, I used it for a 3 gal tank and it heated it to almost 78-80 degrees sometimes. Luckily I had a thermometer on the outside side of the tank so I just unplugged it if it got too warm. I just had one Beta fish in the tank, if you have any other fish other than a goldfish or a guppy I would definitely try to get a bigger tank so you can put a heater in it :) Hope this helps!

We just bought a new MK32E for our daughter's barn. The heater on mine was attached directly to the underside of the water pan while this newest one has the heater sitting away from the water pan, suspended from a small arm. Ours froze up last year at -25 degrees but increasing the thermostat setting seemed to solve the issue. With the heater away from the pan and at -40 a 500 watt heater might be taxed beyond its capacity. I used to put a 100 watt light bulb inside our unit in the winter just to be sure it did not freeze during those few sub zero days.

The Fluval Edge 25W heater is preset. So as long as the ambient room temperature is 65 degrees or more it should work fine. This heater automatically turns on when it is not 78 degrees in the water and will turn off when it reaches the correct temp. However, if the area you are in is cold, the heater will never reach 78 degrees. I ended up getting an adjustable heater for my tanks because of this problem, a 25W Hydor heater.

I would recommend finding some higher quality heater for your 300gal tank. You could find a 1000watt heater or just run 2 heaters

My heater started working immediately. I suggest not leaving it out of water for any length of time. It will get hot to the touch very quickly. Even though it has a constant on feature, there is a limit to how hot the tank can get which is a combination of the tank size and the ambient temperature of the room. I am using mine in a 1.77 "goldfish starter kit" (who are they kidding) with an added external light and this heater and my Betta is doing fine. He is a classroom Betta, and my room gets cold!

What size is your Tank? Does the red light come on on the heater to show it is on when heating? I have a 75 gal. tank with a 300watt heater and it stays in the middle 70's.

I have a 2.5 gallon tank and it took my heater more than 2 hours to warm up. I was also concerned that it wasn't working but it warmed up after around 6 hours I would say. It stays at a constant 76-78 now. The red light is never bright unless the room is completely dark so I wouldn't worry about that unless it becomes competly unlit

I have a 30 gallon tank and it maintains 64 degrees like a charm. I would guess that even lower temps are very achievable.

I would go with a 150 watt heater just in case you need more heat to treat a disease later on besides more watts will be able to heat the water faster and maintain the temperature easier where low watt heater will stay on much longer, But it also depends on the temperature you have in the room where the tank is kept.

What everyone else has told you here is true. The only thing I would add is that you may want to play w/ the time in order to fine tune it. I have an 80gal. tank, & have it come on for 1.5hrs in the morning about 6am & again at 6pm. This satisfies all our needs for the day. If you have a cheaper rate at night, time it to come on for the amount of time you determine so that it goes off at the time the rate does too. If the heater is satisfied before the time is up, it won't be on anyway...Remember to reset the clock after a noticeable power outage however!!!

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.

It's on Celsius and Farenheit, check again ;) (I got this heater on my tank and I know). Btw I recommend it.

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.

Depends on your room temp. And gallons of water. My room temp was around 62 and I had 150 gallons. Easily kept my water temp at 78 with 800 watt heater

I'd personally get a smaller one. This article says 100watts is too much for a 10 gallon tank. Here's the reference article - http://www.thatpetplace.com/fish-tank-heaters-article

This 150 watt will work for your tank. Most sources suggest 3-5watt per gallon. Lights create heat and regular room temp affect the waters average before heating. Mine doesn't come on much in the summer at all. If tank is on an outside wall it will be colder than the middle of your house. Same for if you live in warmer area like Texas vs michigan where it's always colder. I'm using it on a 75gal right now. Will add another in winter if it can't keep up.
