It's a 75 gallon glass - the heater is directly in the middle of the tank set vertically. It shot up the 3 degrees after I installed my canister filter. I now have the heater set at 76 and my thermometer is reading 81. Before I added the Fluval 405 both my heater and thermometer were reading the same. Is it normal for this to happen?
Thanks
 
Does the canister have a heater in it? If not I would definetly get a new heater if its that off. Also check to make sure you arent turing the dial the wrong way.
 
Have there bee any other enviromental changes? Like the heat in your house?
 
The exact same thing happened when I switched to a canister from the HOB filters on my 55 gal. I attributed it to the great increase in water circulation. I adjusted my heater appropriately and haven't had a problem since.

*chuckles* That was gonna be my assumption on the matter, too! :P

Hmmm... maybe it IS the difference between canister and HOB... anyone else have something similar happen??
 
In that size tank you should really have 2 heaters. One at each end. What's probably happened is the increase in water flow the heaters is probably not getting a good of a reading because of the circulation. Try moving your outtake tubs so their is less current on the heater.

I do agree with this advice. Better to have two 35 gallon heaters than one bg enough for a 75... or keep the one you have turned WAY down and add a 35 to the other side and balance the temps between them. That way if one of your heaters goes down and stops working, you have a backup... also, it helps to distribute the heat better and more thoroughly. I also believe in having at least 2 separately working filters on a tank so large for some of the same reasons. Better water flow and a backup in case of one of them going down. ^__^
 
I would also say its do to the increase of volume in water movement. Could be a coincidence that your heater needed calibration at the same time you added your new filter..

My guess would be that the water had alot more contact with the air in the room when pumped through the hob's. with the Canister there is little or no contact, directly, with the air in the room. Water stays more insulated. Plus the canister still uses electricity, which produces heat. My guess.:)
