I kept mine horizontal for a year, with no problem at all. Eheim Jager's are a very good product from my experience. I took a chance and kept my 200W heater in a sump-well that had 4 tanks connected to it, for a total of 185 gallons, and it handled the work flawlessly. For a single tank set-up, I would follow the manufacturer's guidelines, which in your case is to use a 250W heater.

It is fully submersible - and mine keeps a 50 gallon perfect 24/7. I'd guess it could handle much more than I am throwing at it.

This heater was a good heater for several months but something went crazy with it & the heating element went crazy & cooked my tank. It spiked a very high temp & lost almost all my coral & a few fish. I had it in my sump. Don't know if it was just this heater or if they are all faulty. Sorry I couldn't have been more help.

In my 120 aquarium I used the 250watt. Going a little bit on the large side allows for a more stable water temperature. And yes, heaters can be placed in any direction, including horizontal or upside down, and still work.

I would say yes - I had mine in a one gallon plastic tank with no problems. FYI - when you change the water, make sure you unplug the heater, even if it's just going to be out of the water for a little bit. It will overheat pretty quickly and quit working. Voice of experience :-(

It depends on how warm you keep the room that the aquarium is on. If you keep the room temp at 75F, the water temp will be about 73 in the aquarium. Therefore if you only need the aquarium temp to be 78-80, that means it only has to raise the temp 5-7 degrees. You go by the room tempuature to determine how much wattage of heater you need. I personally use two on my 120gal to keep a more consistent temp throughout the tank because I have a cannister filter on both ends.

I use it for a five gallon tank and it is great. A one gallon tank might be to small. Prior to getting this I had a flat heater that was under my gravel that auto censored to keep a tank at the right temp. The only problem with it was I needed to have more control of the temp in the. You might try finding it, sorry but I don't remember what kind it was, but I know it was for smaller tanks.

Look at the size chart, 300-watt only good to 80-85 gallons. You would need something like 2 500-watt heaters or 1 1000-watt heater. Good luck.

The heater can be completely underwater so no fear of eletrecuting yourself. Yea you can put it at the bottom horizontally. I am doing that with mines in a 75g. So far it's been working great! Pretty stable and since I have the 300w in a 75g, it heats my tank to the desired temp quickly.

I don't like slowing down water flow in the tank. The heater should be kept in the main body of the tank. It works best there.

you would be better off looking at a 25 watt heater the hydor theo is a good option for nano tanks

I have this tank for a betta. The heater I use is a 10-watt Marina compact heater, it is stored in the filter compartment. Marina C10 Compact Heater, 10-Watt

This "tank" is only 2 gallons and the surrounding air in your home should be warm enough for any fish that would be suited for this little tank. Also, it's plastic, a heater would probably damage it...

No, you will have to purchase a heater on your own. Get a submersible 25 to 50 watt heater that is designed for a nano tank.

I purchased a Marina C10 compact 10 watt heater with this tank and the heater is self regulating. I keep an eye on it and it works perfectly so far!

One gallon tank? This would be seriously too much for that. I'm using it in a 26 gallon tank. There must be smaller and cheaper heaters for small tanks.

I am using the 300 watt in a 120 gallon for aquaculture, it seems to handle very well, even outside. I would probably use 2 or a larger one for 300 gallon?

It has a regular propane attachment so it shouldn't matter what size tank you sit it on. The only issue I can see is that the heater would sit perpendicular to the ground. I'm not sure how that would effect the operation.

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.

I placed a heater in my tank. I have had it for a year now and like it a lot.
