ryanjury Posted September 1, 2009 Report Share Posted September 1, 2009 It is not normal, your heater has a thermostat in it that should turn the heater on and off to regulate the temperature.. Reasons this temperature variation may occur: A very very cold night A heater that is too small for your tank A poor quality heater (what brand is your heater?) which has a useless thermostat in it.

Bilbo Posted September 1, 2009 Report Share Posted September 1, 2009 Hi. This is fine and wont do any harm at all but it isnt normal. I have to ask how much water do you have an how big is your heater? It may be that your light or some other thing is adding to the heat into your tank and your heater is set to 25c, or your heater is set to 27c and is not big enough to keep up with the amount of water it needs to heat especially with the cold night we just had. Most fish are fine with a overnight drop of a degree or two, they would get that in the wild anyway. Quote Link to comment Share on other sites More sharing options...

Heater is a 150 Watt It's a jebo We have a 60L After doing some reading up tho I have moved it more towards the filter. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted September 1, 2009 Report Share Posted September 1, 2009 That is pretty normal I would say for the average tank. Do you have a lid for the tank? Quote Link to comment Share on other sites More sharing options...

Morcs Posted September 1, 2009 Report Share Posted September 1, 2009 150W for a 60L is more than ample! I have a 300W on my 250L and I have the exact same fluctuations in temperature between day and night. Nothing to worry about. Quote Link to comment Share on other sites More sharing options...
ryanjury Posted September 1, 2009 Report Share Posted September 1, 2009 Heater is a 150 Watt It's a jebo We have a 60L After doing some reading up tho I have moved it more towards the filter. Jebo is your problem All of the jebos I have ever had have had massive temperature variations (I only have 1 still going from the 8 or so I used to own) that is until they stop working altogether or stick on and cook the fish.. If I was you I would replace it asap before it stops working or sticks on and kills all your fish.. I would say the variation is not based on being overnight and you will find the temp will do random things every so often it is just what those heaters do. To the people that say it is normal.. How can that be? This person has a 150W heater in a 60L tank that is massively over heated, the same thermostat is in the heater why the massive temp variation? Yes it is harmless but I wouldn't say it is normal at all.. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted September 1, 2009 Report Share Posted September 1, 2009 AFAIK most jebos have a bimetallic strip that bends and forms the circuit only after the temp has dropped over a degree or so. then it takes time to heat up. I don't like jebos either, their coils aren't long enough, and they lose their heating capabilities pretty fast. What sort of thermometer are you using New_to_fish_world?

Caryl Posted September 1, 2009 Report Share Posted September 1, 2009 Perfectly normal. What is the room temperature overnight? This has a bearing on tank temperature and how fast it drops or how hard the heater has to work to keep it up to temperature. 25 from 27 is nothing and still within standard temperature range. My tank sits at about 22 :roll: Quote Link to comment Share on other sites More sharing options...

I don't like jebos either, their coils aren't long enough, and they lose their heating capabilities pretty fast. Yeah that is how they work I have found the temp does vary alot with them, and every so often you look at your tank and it is at something random like 22C so you turn it back up, it stabilizes at say 26 then a few weeks later is upto 29 again.. They just do random things until they die. I guess you get what you pay for, I was a cheap ass when I brought them and was paying $20ea for 300Ws now I look back and would have been better putting that $160 into 2-3 descent heaters at least I would still have some going now.. It hasn't been all that cold around here recently unless they had their tank in the freezer I would say the 150 would be more than enough grunt to keep the temp even.

Morcs Posted September 1, 2009 Report Share Posted September 1, 2009 Every Jebo heater ive had has had large fluctuations in temperature. Ive only had my 4ft setup a month and im still adjusting every few days to try and get it to stabilise. Aquaone heaters though arent much more expensive, and always hold really good stable temperatures. Quote Link to comment Share on other sites More sharing options...

I wonder if wet pets will do a swap since they told me that the Jebo heaters are the best Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted September 1, 2009 Report Share Posted September 1, 2009 I always stick to the brands that have a massive warranty - jager/eheim; fluval (old or new), and rena. even though you pay more for them - they don't seem to get spoilt. I mean my rena lasted me more than 10 years! so on an annual basis its cheap as chips. if they do get spoilt, you have a rock solid warranty so just trade in the spoilt one for another. Im a tad disappointed at the juwel heaters too. some work really well and some don't. there isn't that much consistency. Quote Link to comment Share on other sites More sharing options...
Scottie841 Posted September 1, 2009 Report Share Posted September 1, 2009 Our 4 foot tank has a jebo in it and it has a tep range of about 3 degrees and the fish are fine. If anything I think a drop in temp overnight is a good thing because it is what would happen naturally. It is not normal for the fish to have a constant temp all the time. If I was you I would leave it how it is and just check the temp when you feed them to make sure it is not too hot. If you are unsure about anything you have been told at one shop go to the other and ask one of them for advice and see what they say Quote Link to comment Share on other sites More sharing options...
ryanjury Posted September 1, 2009 Report Share Posted September 1, 2009 There is no doubt the fish would be fine the problem is the heater shouldn't be fluctuating that much and with a jebo heater it is only a matter of time until they die.. I would go back to the shop and try and convince them to give you your money back to buy another one.. Aqua ones are quite cheap on trademe http://www.trademe.co.nz/Home-living/Pe ... 213107.htm Its a shame you didn't join the fishclub earlier I just brought a heap of rena heaters off a guy for myself and everyone in the club for $20ea, I might be doing it again so watch this space..

ryanjury Posted September 2, 2009 Report Share Posted September 2, 2009 As Scottie said it will be fine that was why I linked you to it If I didn't buy all the rena's/fluvals/jagers I just have I would have gone through this guy http://www.trademe.co.nz/Home-living/Pe ... 397376.htm he doesn't seem to have any 100W's at the moment but quotes the manufactures 3yr guarantee which implies he will actually give it to you..

If they are quoting a manufactures 3yr guarantee make sure you get the origional proof of purchace or it means nothing to you. It might lay to ask if he can give you a copy of his recept. It is all good saying it has a manufactures 3yr guarantee but if the product if 4 years old it is not covered Quote Link to comment Share on other sites More sharing options...
