D6C1 Posted April 1, 2006 Share Posted April 1, 2006 Does anyone in sydney run their big tanks without heaters? eg 6x2x2. Its such a large volume of water, that the temperature fluctuation should be gradual. Would one get away without running a heater? Does anyone do it like that? Even in winter? I got african and american cichlids. What minimal temperature can cichlids withhold? Link to comment Share on other sites More sharing options...
Josh Posted April 1, 2006 Share Posted April 1, 2006 I am still not running a heater in my tank. But it will only be a month or two until it goes on Josh Link to comment Share on other sites More sharing options...

timmy2422 Posted April 1, 2006 Share Posted April 1, 2006 If you make a fish room just using cool room panels you will cut heater use down by alot Link to comment Share on other sites More sharing options...
trofius Posted April 1, 2006 Share Posted April 1, 2006 Even big tanks need heaters. up here in rochampton i have 2 X 300w heaters in the sump to my 8x2x2. In winter the temps up here get down to about nearly zero, inside it is maybe 12, the tanks without a heater will drop to about 15.....way too cold, the other tanks get reverse cycle.

Colfish Posted April 2, 2006 Share Posted April 2, 2006 hi Toufic the temp. drop in a 6x2 would be very slow, but the rise would also be a lot slower. when the temp. gets down to around 22c, cichlids tend to become very sluggish. i would suggest the use of heaters, even if you only lift the temp to around 25/26c you will see a marked improvement in thier activity and appetite cheers; C Link to comment Share on other sites More sharing options...
CThompson Posted April 3, 2006 Share Posted April 3, 2006 I would disagree that cichlids (mbunas) get very sluggish at 22 degrees , however, I would fully endorse the comments that a big tank in Sydney would need a heater. It absolutely will – unless your house is heated, you must put a heater in the tank. FYI Mbunas will happily live and breed at 22 degrees. It is the target tempreture I aim at, the problem is in summer keeping it there. Craig Link to comment Share on other sites More sharing options...
Bijengum Posted April 3, 2006 Share Posted April 3, 2006 I would agree with Craig. The only problem I have ever had with low temperatures is a sudden drop when I added water straight from a bore without measuring it. I have had heaters fail and temps slowly drop to below 20 degC without any noticeable problems. In fact I think I have tried to keep temps too high in the past and would aim in the 22-24 area especially for the tangs.
