    Hi everyone... I'm having some trouble keeping my tank temperature at a consistent number...I have both a 55 gallon and a 5 gallon tank...I'm most concerned about my smaller tank as the temperature really varies from 75-80 a day and I know that's not good for my Betta...I have a 7.5 watt heater in there...I have to plug and unplug the heater numerous times a day to try to keep it consistent and it still doesn't work...any sugggestions on a new heater that can keep both my tanks at a consistent temperature? Thanks! Sorry should have posted this finding a proper heater!

    If the heater for your 5 gallon is a cheapo heater, that may be why the water temp is so inconsistent. I know how it is to try and save money, but sometimes you just have to put in a couple extra dollars and find a decent heater. :)

    Hi...yes it is a cheap heater but I couldn't find any other lower wattage heaters..don't I have to stick to a lower watt for a 5 gallon?

    Great thermos

    50 watt aqueon is a good heater for 5 gal with my Betta. Also works in my 10. Preset at 78f

    I used the 50W Aqueon in my 5g betta tank too. Worked great. I still have it and it is in my 10 gallon now. Still working great lol

    Usually yes, but there are heaters that are 25 watts and are rated for use in 5 gallon tanks. If you can find it, I have heard that the hydor theo 25 watt is good for a tank of your size. It has an auto shut-off and it has a dial do you can set your preferred temperature. The temp shouldn't fluctuate as much with this heater and it currently goes for 15-20 dollars on Amazon. :)

    I bet the smaller tank heat bouncing is more due to room temp.

    Is the room AC on 24/7 or does it go up and down all day. 5 gallons will drop or go up to room temp rather quickly.

    And that Zacro pack is what I have. I have two on my tank. 1 water 1 air temp.

    I've used this in a 5g tank and it's pretty consistent. It has automatic shut-off as well. It's also considerably cheaper than a Hydor or Aqueon.

    And if you're looking into the thermometers that tommywantfishy recommended, I can vouch for them, but you'll find the same thing cheaper here.
