Default high temp without heater or lights!!!

Hi all,

I just noticed that my tank's temperature is at 81.5 F without my heater being plugged in or even my lights on!!!

Is this normal??? My guess is no!!!

I have 4 power-heads plugged in with a remora-pro protein skimmer with the mag350 pump.

I noticed that my tank's temp goes down as my lights go on because I have a clip-on fan that operates during "day-time" hours. My tank's temp drops to about 79.5 F

What can I do as I am getting a bit worried.

Thanks

Default faulty thermometer

double check the thermometer to see if its working properly before adjusting anything else (compare the temp with another thermometer or your thermostat)

It could well be the Mag pump. I run a Mag5 on my remora in a 46 gallon. My temp stays at 79F (quite a bit above room temp as I like the house relatively cool) and my heater is virtually never on.

Mags are known to be big power hogs which produce a lot of heat.

A 2-3 degree temp swing (78F-81F) is okay in our tank.

It's your pumps creating heat, is there a way to keep the fan on all the time? It will help to gas off CO2 as well.

What size tank is it and what type of powerheads? Many pumps and powerheads generate a fair bit of heat.

Try unlpugging one or two powerheads for a day and check your temp. That should give you an idea of how much they are contributing.
