Heater Question

[jfclk33]

I was wondering if a 100 watt heater is too much for a 10 gallon tank? I am getting one to set up as a hospital/QT tank (will thoroughly clean between uses).

My concern is that if I need to raise the temp to 86 or so for ICH in the winter time, a 50 watt heater won't keep up since room temp is around 70 deg. On the other hand, I don't want to fry them in the summer if using as QT tank set at 80 deg. and the room temp is set at 78 deg.

I have a spare 200 watt heater laying around, but I know that is too much for a 10 gallon. I've been told that it will heat up the water too quickly and get above the set temp and I don't want to have the same problem with the 100 watt.

Thanks for any help.

Too much wattage. A 50 watt will have no problem getting up to the high 80s with 70 degree room temps. I run 50s on my 10 and 20 gallons as I find 100 is too hard to regulate on them (and I keep my winter home temps at 68 day/62 night).

OK, Thanks. I'll get the 50W.

50 or 100W will do the same... What's important is to keep the temperature stable. Temperature Controller will help.

If it's for keeping the temperature at 23C°, go for the 50W.
