About how long should it take to heat a 70 degree 5 gallon tank to 78 degrees?

It took several days for this heater to reach the set temp in my house. It may have been due to the fact that my house is a bit on the cold side, but I have not found this heater to be able to handle temp swings very well.

I just did this 2 days ago. I filled my tank around 3pm and it was 70 degrees by 6:00 it was at 78 degrees. I put my fish in before it was fully heated Nd they're fine! GREAT heater! Hope this helps!

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.

I'd say an hour or two max. This is the perfect heater for that size. I have mine in a Fluval edge 6g.

Not long. You want the temperature change to be slow anyways so it wont chock the system

It took mine under 15 minutes to heat my 2.6 gallon tank from 74 to 78 degrees. If I may, I would suggest that you check out a 50 watt heater, the 25 w is meant for 2 to 4 gallon tanks.

It has consistently held 78 degrees in our 2.5 gallon tank since we got it. It will most certainly do it in your 5.5 gallon tank. It is the BEST heater ever. You will not be sorry with this purchase.

The temperature varies. It brings the tank to a boil and holds it for several hours before briniging it back up to a boil again. It always comes out scorching hot my guess would be above 185°F.

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.

Hi -- I have a 2 gallon tank and it is working good. I recommend buying a cheap additional water thermometer and then setting the temperature on the heater to be slightly lower than the desired. For example I set my heater to 74 to get an actual temperature of 80F (as measured by the second thermometer).

I'm using it in a 2.5 Gallon with a Betta....it works great! I used it all winter when our house temp. gets down to 65 degrees at night. The tank remained at a steady 80 degrees F. I don't use it in summer because our house stays at around 78. I recommend getting a thermometer as well....

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.

We heat a 400 gal hot tub from 70 to 100 in about 3 hours. Hope that helps. Unsure of BTUs.

Buy a bucket.. I used half mine on a 55 gallon with the treatment plan on the bottle. But it did work as it said.. I also brought the temp up to 86 slowly

This is based on my Primus two burner camp stove. Boiling 3 qts of water takes 15 min and uses 1.4 oz of propane. The 1 gal tank fill is 4.25 pounds or 68 oz giving 728 full burner minutes. My estimate for cooking dinner for 4 is 40 full burner minutes or about 18 dinners per tank. Breakfast for me is maybe half that and I don't cook lunch so 60 min per day gives me about 12 days. If you cook more, estimate burner minutes per day to figure how long 728 will last. Hope this helps.

what size is your tank? I have a 300 watt in my 90 gallon saltwater . Temperature set at 78 and it stays at 78. I ran it at 82 degrees when it was cycling

I was not able to get it to heat a 20 gal or a 10 gal, so I have it in a 5 gal tank and it still doesn't heat to the level it states it will. I put it in a smaller tank with some fish that don't have to have the water temperature to be maintained at over 75, so it's working find in that situation. I suggest getting a submersible heater that allows you to adjust the heat to the temperature you want, that's what I now have in both of my larger tanks now and I was very disappointed when this one wouldn't/couldn't keep up with at least a 10 gal tank. Good Luck!

You can also high boil 7 to 10 minutes & low boil 5 minutes. If you boil too long the water diminishes.

I have a 25 gallon tank which stays cool at 67 degrees 7 days a week. I have gotten the temp to stay as low as 64 degrees. Without knowing what you want the 10 degree drop to be, I wails say it's a safe bet that you can drop the degrees to your desired temp. Hope this helped you.

I really can't answer the question. I have a 16x24 foot garage and setting the heater on 1 and 1/2 it gets up to 70 degrees. So I don't have to set it that high. I really don't use it that often so I can't tell how a 20 lb. tank would last.

I can't say for sure but I have it in a 100 gallon system in a basement and it keeps it at 70 degrees with no trouble. I would get one, if it can't keep up grab a second one.

i got a simple small tank heater, in which you can place underneath the thanks. Keep temp at 78
