In Tank Filter, issues??

[currcat]

Hi, I have a quick question for anyone that knows anything about the sumergable/in tank filters (Whisper brand). I have one in my goldfish tank and im wondering if it is causing the water to heat up. The therm says it is about 77 deg in the tank, which seems quite high considering I dont have a heater in the tank. Has anyone else noticed a change in water temp with one of these filters?

Thanks,
Catlin

I'm not sure if the filter is heating it up, but have you taken into consideration how warm the room is?...just a thought....

I use a lot of in-tank filters (different brand) and yes, they do contribute to heat load on the tanks. Look at the filter specifications - the wattage of the unit can be considered a heater of that wattage in a constant-on mode, as all of its heat loss is to the water.

Do you have flourescent light/s on as well?? This can also contribute to the heating of the tank. What is the temperature of the room the tank is in?

We do keep our room around 70-75 degrees so that could be part of it. Also I do have a flueresent light, but I rarely keep it on for more than an hour, because of the heat it create. My goldfish seems to be healthy, so should I worry about the temp? Or should i go with a different kinda filter?

What size tank do you have? I would go with a Whisper HOB power filter. Use my Whisper Power Filter Guide below specifically for Goldfish.

Model 1-3i - Up to 2 gallon tanks 20GPH

Model 10 - Up to 7 gallon tanks 90GPH

Model 20 - 8-15 gallon tanks 105-125GPH

Model 30 - 15-25 gallon tanks 145GPH

Model 40 - 25-35 gallon tanks 210GPH

Model 60 - 30-40 gallon tanks 330 GPH

Model 60 and Model 20 - 40-50 gallon tanks 445-465GPH TOTAL

Model 60 and Model 30 - 50-60 gallon tanks 475GPH TOTAL

Model 60 and Model 40 - 60-70 gallon tanks 540GPH TOTAL

2 Model 60s - 70-80 gallon tanks 660GPH TOTAL

3 Model 60s - 80-90 gallon tanks 990GPH TOTAL

4 Model 60s - 90-110 gallon tanks 1320 GPH TOTAL

You want your tank water to circulate 10 to 15 times an hour. So a 10 gallon tank needs 100 to 150 GPH. :dive: :idea:
