Temperature

Hi all,

I just wondered if my heater is faulty or not because i have it set at 25 degrees c but my thermometer says 32 dgrees c. Whe i put my fingers in the water tho is feels chilly. I even bought a new thermometer and still reads exactly the same. It is not in direct sunlight and has no other heat source aimed at it. Am a bit worried it is uncomfortable for my fish but dare not drop it any further incase it goes too cold but the reading is above the green.

Can anyone help am all confused lol

so far i adjusted my heater according to my thermometer, the instruction in the heater should say use a thermometer right? but i also read somewhere that you need to drop your temperature slowly. but how slow is slowly?

Hmmm, that is odd. I'd expect 32 to feel warm to the touch, and it is a bit high for most fish. Strange that 2 thermometers should say the same though. What fish do you have?

If you drop the setting on your heater, the water can only cool as fast as the ambient temp will allow. To be certain, you could drop your heater by a few degrees at a time, lowering it further when your themometer confirms it has dropped.

sorry, i meant slowly as in dropping like a degree at a time on the heater,small tank +cold room temp could drop temp too fast.and yeah 28d would still pretty warm, lol don't trust me on it, my experience is not much at all

What kind of thermometer is it? If its a stick on the glass outside the tank, they are usually wrong, if its an internal thermometer it should be correct, but as stated, 32c should feel warm and most community fish wont appreciate it that high.

some of the heaters ive used say to let them sit in the water for 15min or so, and then switch them on. the first time i used one like this i just switched it on straight up and whatever i set it to never matched with the thermometer. so i switched it off for 15min and it started matching after that. perhaps ur heater is similar?

do u have sufficient flow around where the heater is?

What position do you have the heater in? Upright, diagonal, horizontal?

I have moved the heater dial down a few degrees to see how it goes.

It is an inside thermometer, of which both where. One is a dial one with needle and other is a glass easy read one. the water feels chilly to the touch but surely 2 different thermometers cannot be wrong.

The heater is at opposite side of tank away from filter and thermometer. At far end in horizontal position.
