After being out of the hobby since I was a kid I got back into it when I got a 3 gallon kit for Christmas. Needless to say I caught the itch, and ended up upgrading when I saw the Aqueon 29 gallon kit on sale at my lfs
. I am using the heater the kit came with (All Glass 100w). The heater is doing its job well, and holding all areas of my aquarium at a very steady temperature. My only concern is the fact that it cycles (turns on/off) VERY frequently. It will be on for a few minutes, then shut off for a few minutes, back on, etc... Today, when I did a 20% PWC
, I misjudged the aquarium temperature slightly and it ended up cooling down about 1.5F. I expected the heater to stay on and get the aquarium back to its set temp, but it continued to do its quick on/off cycle.
I have the heater positioned near the corner about 6" from one of my HOB
's intake (I have 2 HOB
's, 225gph total). I know the flow in my aquarium must be decent as the temperature is uniform, but the heater is in a more low flow area of the tank. I'm sure this is the reason why it turns on/off so often.
My question: Is it bad for the heater long term to turn on/off so frequently? Or should I try to move it to the middle where there is more flow, but wouldn't look as good?
Thanks in advance.
