Heater Problems

[don5aces]

Hi i've got a juwel 125 litre tank. I have 2 thermometers in my tank and it is currently telling me the tank is at 27 degrees, i want to lower the temperature but whatever i turn the heater to it makes no difference, I took the heater out and it doesnt even seem to be on but if this is the case wouldnt the tank be a lot cooler?

I hope someone can help, thanks

Leaving it atleast 24hr's to adjust?

If the room your in is warm then maybe that is why your tank is staying at 27'

I could leave it a week, it seems set on the same temp whatever i do. I just dont get it, cos if the heater was broken wouldnt the tank be a lot colder than 27 degrees.

not if your room is warm, my betta tanks are unheated and remain around 27 degrees

yea the flat is pretty warm, and that would make sense. would it stress any of my fish being that warm, ive got a pair of rams and i know they like a temp of 24

Test your heater by placing it in a large mixing bowl or wasing-up bowl or similar. Fill the bowl with cold water from the tap. Add a thermometer, check the temperature. Add your heater to the bowl, making sure it is submerged. Return to your bowl frquently and make a note of any change in temperature. This will tell you of any problem you may have with your heater.
I have to say, though, I agree with the other comments. My money would go on your room being fish-tank friendly.
