Whisper 200 watt submersible is cranked to the highest temp.

And the water is only 80 degrees. is this a defective heater or is there some way I can get more heat out of this puppy. It appears that Ich is running amock in my tank and I'd like to crank the heat up a bit.

How big is the tank? If it's over 42 gal, you may have to put a temporary 100 W heater in.

What size tank and what is the temp of the room it is in? I have a 200 watt on my 50 and had no trouble getting up to the high 80's, and I don't keep my house very warm, low 70s at the most.

Actually I overshot doing ich treatment and they spent a few hours at 90+, none the worse for wear though

Unless it is a pretty big tank, I would say you have a weak/bad heater

wow, thanks for the input. You guys seem pretty altruistic. I have the heater in a 55 gallon tank and my apartment is usually around 75 degrees. I just bought the heater so I was thinking of exchanging it or something. seems like it should put out more heat than it does.

I think the general rule of thumb for heaters is 5 W per gallon.

I've got a 300 W in my 58 gal and my apt temp is about the same as yours. I had no problem going up to 88oF.

I'd keep the one you have and add a 100 W. That way, if one heater dies or gets stuck in the on position, you will be less likely to freeze or cook your fish. If I had it to do over, I'd get two 150s for this reason.

I always overbuy heaters.

My 10gals have 100 watts, and my 29gal has a 200watt.


And have never had trouble with my temp

My large tanks all have a single 300 watt heater. They stay around 79 degrees right now (They're set to 80) and my apartment is mostly unheated because I have a gas furnace and don't want to pay the gas bill, around 70 degrees. I should get more but never have.. I have extras on hand, just not in the tanks.

Just a note guys... I have 2 new whispers and BOTH of them are cranked to the max, in appropriate sized tanks, and neither will not go above 78-80.

I am convinced it is a built in safeguard for newbies, whisper thought would be a good idea apparently.

Oh well, that's what I get for buying equipment hastily to set up additional tanks.



Back to the ebos and wons.

Its a good idea, IMO... Just not for ich treatment I'd actually consider this a useful feature.. ideally you'd want to have limited heaters like this to safeguard your fish from boiling, with an extra backup to use when you need to go higher.
