Hood lights heating water

[alex818]

I have the Eclipse 3 Aquarium hood on a 37 gal tank (has approx 30 US gals of water in it) and it has the standard fluorescent lights that give off a little heat but does'nt seem too much.

Without plugging in my heater, my water temp ranges from 80 to 82 degrees.
I dont have any fish in it yet but im worried about temperature fluctuation. I can keep my heater plugged in and it will turn on if it drops below healthy conditions.
I keep the tank lights off at night but the temp doesnt seem to drop much.

In general, will it hurt my fish if the temp fluctuates between 79 and 82 degrees if it fluctuates slowly?

Is it safe for fish to stay in constant 82 degrees of water?

Summer has just ended and my room temp is already about 79 degrees but im sure in the winter it will be much cooler and my aquarium heater will keep the temp stable.

Should I be worried?

im not sure really if i can help bcus im probaly completly wrong
but i have a 4 ft tank that says pretty hot all the time
=i couldnt put heater in incase it got to hot i was more worried of taking it to high or out there limit then keeping it at the heat thats right

i have pc running and i dont get much air thru my room so it stays at 77-25ish
without light or heater in but i get around 8 hours of sun and gets trapped withing concreate walls then in the day when i turn the light on for around 12 hours
it goes to highest on (hot day)28 which is pefect for my fish

i thought beings these fish i have are from places like india or usa but hot at night it still doesnt cool down that much
i have got a brandnew 300wat heater to put in soon as it gets real cold
But i would say aslong it doesnt go out there heat limit then it should be fine and you shouldnt worry to much

High temperatures have several effects. Probably the most important is that Oxygen, that the fish depend on, dissolves better in cold water than warm, therefore, in the summer months, your O2 levels will be reduced. For that reason, I would suggest you understock your tank.

Many fish are quite happy at high temperatures, go for really tropical species, they are better adapted to heat and lower O2.

Most fish live faster shorter lives in high temperatures.

but do i have to worry about heat fluctuation? its normally between 79 and 82 but most of the time no less than 80 degrees.

Im not possitive, but i think your lfs may sell a chiller to cool it down. If the temp ranbes above 82 it is NOT healthy try to keep it about 74-76.

A gradual change of a few degrees F over the course of the day is not going to be a big problem really, sudden changes are.

>>> NOT healthy try to keep it about 74-76.

Generally true, however, as I said before, there are fish, Discus for example, where a temperature of 80F would be pretty normal. I've swum in the Amazonian rainforrests, the water can get pretty hot, especially in the blackwater rivers like the Rio Negro, masses of fish there.

i was just re checking the right heat for mine and its average between

76-82 around 24-26 c

my tank is normaly 24ish and goes to 26 is this ok
p.s its 25c now and by 10 will be 26 during the night back to 24-25

My tetra, barb and gourami tank is consistently above 80F (warm part of the house). In the hot summer it was regularly up to 84F and I only lost an elderly pencilfish.

Thanks all I guess I shouldnt be too worried.. I think the room temperature may be a factor as well. Winter is around the corner and things should cool off a bit.

Too much fluctuation can cause stress on your fish. I don't think 82 degrees is necessarily dangerous, but in the long term, it might be harmful.
I have an incandescent bulb in my tank and I notice that leaving it on causes my temperature to rise too. As long as I turn it off at night, though, it doesn't really affect it, so if I need to raise the temperature for disease treatment, I leave the light on, and that solves my problem for needing a heater. Also, make sure your water line is over your thermometer. This can cause a messed up reading.
