imsweet Posted May 22, 2009 Report Share Posted May 22, 2009 I wouldn't expect so, most (if not all) have a thermostat so once they reach temp they switch off. Meaning, if winter makes the tank water cooler the heater should just work a little harder to reach temp. My theory anyway. Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted May 22, 2009 Report Share Posted May 22, 2009 I find I have to turn my Discus tank up a couple of degrees over winter - just because I do frequent waterchanges and can't always guanrantee the temp to be the same, and less strain on the heaters Quote Link to comment Share on other sites More sharing options...
SamH Posted May 22, 2009 Report Share Posted May 22, 2009 No need. The heater always keeps the tank temperature the same no matter what the environment around it does, except if it's higher than the set temperature or if it's extremley cold.

aaron11 Posted May 22, 2009 Author Report Share Posted May 22, 2009 they are aqua one ones from memory the temp is goin up maybe the 55 watt one is too small but i think i always had my tanks around 25 and the other one 27 put them up a bit over 2 days its very cold here hehe im just about sittin on top of the gas heater Quote Link to comment Share on other sites More sharing options...

phoenix44 Posted May 22, 2009 Report Share Posted May 22, 2009 I had a rena that lasted me about 9 years. konked out last year i think. still works, but the thermostat is no longer accurate. best heater i ever had. calibrated to 0.5 of a degree, and what it said was what it heated to.

Caper Posted May 22, 2009 Report Share Posted May 22, 2009 I never change the temp in my tanks. But then, in winter here I have to turn my heat on (electric heat). Now in the what I'll call transition periods between winter/summer and vice versa I might see my heater come on a bit more because it is just not cold enough for me to turn my heat source up.

Dougstark Posted May 22, 2009 Report Share Posted May 22, 2009 If heaters are on a lot of the time then maybe a bigger heater or a second heater would improve the situation. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted May 22, 2009 Report Share Posted May 22, 2009 If your heater is big enough there is no need to turn it up at all. It is controlled by a thermostat that switches on and off to control the temperature of the water regardless of the ambient temperature. If the ambient temperature drops the heater will be on more because of more heat loss from the water. Quote Link to comment Share on other sites More sharing options...
aaron11 Posted May 22, 2009 Author Report Share Posted May 22, 2009 they are workin ok i might get a bigger one if i have problems always good to keep one for a spare i noticed with the aqua one the degrees drops a bit i also got digital temp things are they very accuate cheers Quote Link to comment Share on other sites More sharing options...
aaron11 Posted May 23, 2009 Author Report Share Posted May 23, 2009 the 55 watt one is not doin what it should its on all the time and i turned it up the tank is about 60 litres but thats a guess, so should i get 100 watt or 150 i got a 150 in my 90 litre and its same brand and that goes on and off ALSO my 25 watt one in the baby tank is staynig on too so i will put this one in there and see ! see what happens when you buy cheapo stuff :bounce: and the heater that has lasted 13 yrs is a jager 300 watt i think, i got it from a pet shop years ago and it was second hand then !

Sounds like both heaters are doing exactly what they should be, you just bought too small ones. Quote Link to comment Share on other sites More sharing options...
aaron11 Posted May 23, 2009 Author Report Share Posted May 23, 2009 they were both 2 months old, but i should of got bigger ones, hopefully the 55 watt one will be ok for the 22 litre tank they are fine in the summer just not when its cold like this i will get a few more, dont hurt to have a few spares either !!

jimboNZ Posted May 24, 2009 Report Share Posted May 24, 2009 I generally turn mine up to 28 in the winter, just in case. Back down to 26 in summer Quote Link to comment Share on other sites More sharing options...

Adrienne Posted May 24, 2009 Report Share Posted May 24, 2009 A good guideline for heaters is 1.5 watts per litre so 100 watts for a 60 litre would be fine. A 50 watt for a 60 litre tank will stretch the heater if the weather is cold. For large tanks two heaters or more are a good idea as you then have a back up.

alanmin4304 Posted May 24, 2009 Report Share Posted May 24, 2009 If the heaters are on all the time they are too small. If you wind the temperature up they can't get any hotter than on all the time so the only thing that will happen is that you will cook your fish when the ambient temperature increases and the heat loss from the tank decreases. Get bigger heaters and set them for the temperature that you want. Quote Link to comment Share on other sites More sharing options...
aaron11 Posted May 24, 2009 Author Report Share Posted May 24, 2009 I think its 60 litre the heater is just going up to 27 thats ok but its staying on its 55 watt so 100 watt for that one? the 150 watt in my 90 litre is fine and will the 55 watt for the 22 litre be ok should be aye thanks again Quote Link to comment Share on other sites More sharing options...
aaron11 Posted May 26, 2009 Author Report Share Posted May 26, 2009 got 100 one auqa one heater 22 bucks and its going on and off like it should lady said lots of ppl in there buying them as its so cold i see if my 55 watt one is ok for the 22 litre tank i dont really feel like buying another one for that and 100 watt prob fry them poor babies Quote Link to comment Share on other sites More sharing options...
Caper Posted June 12, 2009 Report Share Posted June 12, 2009 Now as you most know, techinical (along with many other things) I am not! Please bare with me, I know what I want to say here but as usual what I'm thinking and what comes out of my mouth (in this case types) could be entirely different! But, if you have a heater in your tank set at, say 24C when the tank water drops below...the heater comes on till the 24 is reached, correct? So, if you have your heater turned up to say 26C, the heater is going to come on till THAT temp is reached, right? Surpasing the 24, wouldn't it? So, if your heater is coming on more often (that is if heater is working ok) does it matter what temp it is set at because it's just going to come on anyway when the temp drops???? Soooo, wouldn't you only need to consider a bigger heater if your heater is constantly coming on no matter what temp you set it at???? Oh geesh, I don't know if I said what I wanted :oops: :oops: Caper Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 12, 2009 Report Share Posted June 12, 2009 Yes, unless the thermostat is not working. They usually fail through water getting in and that will usually cause the thermostat to jamb in the on position. Quote Link to comment Share on other sites More sharing options...
aaron11 Posted June 12, 2009 Author Report Share Posted June 12, 2009 I got a 100 watt one for my 60 litre tank and put the 55 watt in the 22 litre tank And keep the 25 watt one as a spare!!!!! a lot of ppl i have asked who have fish have said theres sturggle in the winter god in the summer i had to open the lids of my tanks they were getting up 32 degrees !
