cichlid7 Posted January 8, 2009 Report Share Posted January 8, 2009 Get a small desk fan and get it too blow across the top of the water Quote Link to comment Share on other sites More sharing options...
R32GOTMLK Posted January 8, 2009 Author Report Share Posted January 8, 2009 really? how well does this work? its a 800L 6foot tank cheers Quote Link to comment Share on other sites More sharing options...
Stella Posted January 8, 2009 Report Share Posted January 8, 2009 Also running at the moment: viewtopic.php?f=3&t=36138 Describes a bit more of how it works. It seems the bigger the surface area the more cooling can be achieved with a fan. You try keeping COLD water tanks at the moment.... my fish should be below 20 degrees....

Whiskas Posted January 8, 2009 Report Share Posted January 8, 2009 Sometimes just removing the glass top is enough to stop it from getting too hot!! Thats what i do nways. Quote Link to comment Share on other sites More sharing options...
R32GOTMLK Posted January 8, 2009 Author Report Share Posted January 8, 2009 hi ill have to try the fan thanks ive got the lids off and the lights off too. so is the heat why the leaves are falling off? Cheers Quote Link to comment Share on other sites More sharing options...
bedazzled Posted January 8, 2009 Report Share Posted January 8, 2009 I have had to resort to putting a bottle of frozen water in the tank, I got home the other day and it was sitting at 32. I can lift the lid as we have one of those things for the flys and insects that releases a squirt every 7 mins or so and I am worried that it will poison the fish Quote Link to comment Share on other sites More sharing options...

Warren Posted January 8, 2009 Report Share Posted January 8, 2009 The bottle of ice trick works really well in smaller tanks but when you're looking at 800L it's no good. I once tried ice to drop my 1200L from 32'C down to something more respectable. 22 bags of ice later it was down to 28'C. The evaporation method works very well if you only need 2-3 degrees drop.

lmsmith Posted January 8, 2009 Report Share Posted January 8, 2009 I came home on Monday and my 8 tanks were all sitting between 32 - 36deg. I don't know how the fish didn't cook, but I guess over filtration and crazy surface agitation helped. All my heaters are unplugged (at first I thought I had a heater malfunction, but then I realised that it's pretty unlikely on 8 tanks :oops: ), and I've put all the canister filters into insulated boxes with ice packs. The water temp in the filters is 20, so the bacteria will be ok, and it does an amazing job at keeping the temp stable. It only took about an hour to bring the temps down to 27. Not sure if it's just a fluke, but while it works, I'll stick with it. And keep the curtains closed! Quote Link to comment Share on other sites More sharing options...
Stella Posted January 8, 2009 Report Share Posted January 8, 2009 I bought a minimum-maximum thermometer from the Warehouse yesterday like this: http://www.partshelf.com/minmaxrecthe.html They are $10 each. My original purpose was to track the temperature of the room, which is rather handy to know when battling the temperatures in your tank.Each thermometer has a little blue stalk inside which gets pushed around by the mercury and stays where it is left to tell you where the temperature extremes got to. It is reset with a little button. I pulled it apart to see what is inside (the back levered off). It is just a long flimsy thermometer in a U-shape. Not entirely sure how it works, but it does.... Anyway, it looks rather innocuous and could potentially be submerged in a fish tank! This would help track the minimum and maximum without constantly staring at it....

Stella Posted January 8, 2009 Report Share Posted January 8, 2009 Oh, if anyone is interested in getting one of those thermometers, most of the ones when I looked had bubbles in the mercury. These won't work properly. Not sure if there is a way of fixing them. Quote Link to comment Share on other sites More sharing options...

They only turn on if the temp drops below what its set to Quote Link to comment Share on other sites More sharing options...
lmsmith Posted January 8, 2009 Report Share Posted January 8, 2009 ' Whats the use in unplugging heaters? They only turn on if the temp drops below what its set to I thought they were malfunctioning, so I unplugged them, and just haven't plugged them back in. You're right, having them unplugged isn't making any difference. Quote Link to comment Share on other sites More sharing options...
pink_fish Posted January 9, 2009 Report Share Posted January 9, 2009 Well, all my tanks (ranging from 22l to 215l) read about 29C when I get home from work each day at the mo, but since the fish all look fine and dandy, I've left them alone. How hot would it get in their natural environments, anyway? Or, for example, in the big outdoor breeding ponds they use in Asia (Thailand for e.g.)? My feeling is that the fish can cope with some degree of variation. I do add cold water when I do my water changes though, although that doesn't really have all that much effect on the temperature! Has anyone actually had any stressed/sick fish as a result of this heat so far? Quote Link to comment Share on other sites More sharing options...

newfisher Posted January 9, 2009 Report Share Posted January 9, 2009 Funny I thought my heaters and thermostats were not working and went and brought a new thermometor today. Seems 29 is the norm in all my tanks. Fish seem fine in fact the Drawf Gouramis colour looks the best I have seen. Quote Link to comment Share on other sites More sharing options...
