I'm looking for a heater that I can submerge in my 5 gal bucket to raise the new water to the correct temp for water changes. Do you recommend this?

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've been using this heater for months and I can truly say it has been working amazingly good. It is built of quality and keeps the temperature stable, even when doing water changes. It turns on and off by itself, so you don't have to worry about the water being too cold or too hot. I just love it.

Yes it keeps the water at 70-74 is trouble free and looks good in a small fish tank. i would allow 24 hours for it to maintain an even temperature.

I would NOT go with the Fluval heaters... They only heat the water x degrees above ambient. I ONLY use the Rena SmartHeater Aquarium Heater (50W) in ALL of my aquariums... Does the job VERY well and is adjustable :-)

I use it with the three gallon Little Giant water font, and the heater keeps the water just above freezing, and not more than 45 degrees or so. The thermostat seems to work very well. All-in-all, I am quite pleased with it.

To add to my previous comment... I finally had to put a 2nd heater in my Fluval Edge 6 gal tank in order to maintain the set temp. The room in which I have my aquarium is on the cooler side and is around 65 F... I really like the design of the Cobalt heater and the ease of setting the temp and am sure that it will work better in warmer months to maintain set temp, but it is unable to keep the tank heated under the circumstances. It does not heat any better than the Fluval 25watt heater that I had been using.

Hydor also makes a 25W heater, which works the same, but is smaller and might fit in your tank better.

It should work just fine. A couple of things you might want to keep an eye out for, though... One is that if the waters is too small, it might be possible for the birds to come into contact with the hotter parts of the heater, in the center. It does get pretty warm. At least mine does. The other is that a smaller waterer might evaporate off more quickly. But if you are checking a couple times of day anyway, I would think that would work fine.

This item must be used for a 5 gallon bucket (or tall 3 gallon size) or larger. Best for 5 gallon size as larger would take much longer to heat. It does not have a temperature control or on/off switch. Best not to plug in to electric until you have a bucket full of water and then either unplug when removing or transfer to a 2nd bucket. Height of unit is slightly taller than average 5 gallon bucket so wiring always stays outside bucket to avoid electrical shock. You can regulate heat by using a thermometer if need be or the touch(water not element) test. I use mine to heat water for carpet cleaning extraction machine so precise temperature is not critical.

I would go with at least the 50 watt. Probably the 100 would be better. You can always put it a little bit diagonally in the tank. it is ok to fully submerge even the top part. I would consider going with 2 50watt heaters with one on either end of the tank for a more even heating effect. Plus both heaters would last longer because neither one would have to work as hard.

I bought a Marina C10 Submersible Aquarium Heater, 10W. It works fantasticly. I put it inside the white tube, behide the filtersthere is plenty of room and it fits just right. The temp. stay constant and my betta LOVE this Aquarium.

I just set this up today. I wanted a heater with a thermostat and took a chance with the Hydor 25W Submersible Aquarium Heater - Original Theo. It just fits inside the pump area. Doesn't impede on the air hose or electrical wires.

No. You will need to keep an eye on the temperature of the water. It is better to buy a preset heater for the tank or use the timer.

The Aqueon is been unreliable for temp, I bought a Eheim heater and its holding temp well, for a tank your size the 300w should do the trick, rated for up to 250g

It would be fine but bear in mind the ceramic element is fragile. I'd go with the Allied Precision The Premier Line 742G Bucket Water Heater which costs less and won't break. The only advantage I know of would be this will operate in shallower conditions- guessing 2 versus 6 inches water depth minimum. gfci must!

Mine has been submersed in my 55 gallon tank for almost a year. The water level comes just above the dial and onto the cord. I have not had any issues with it heating and my thermometer and heater settings are dead on. I would buy it again. 300 watt version for my 55.

I am constaintly in quest for the perfect heater . I have two of these in my 55 gal tank. So far they have been very accurate .

I use the Tetra Whisper 2-15 gallon heater. I bought it at Wal-Mart for $15. It keeps my tank at 78* all year round.

i would get a 300 W heater for a 55 gal. I believe the general rule is 5 W per gallon of water. 200W isn't quite enough.

yes, I very much like this one; Hydor 7.5w Slim Heater for Bettas and Bowls, 2 to 5 gal It works well without cooking your fish.
