DV. Posted September 20, 2007 Report Share Posted September 20, 2007 I don't have a heater in my 2 foot tank at the moment and i was wondering if i should get one. The water temp fluctuates between about 25 degC during the day to about 20 at night with the AC on. Should i get a heater to stabilize the temp? and if I get one should i set the thermostat low (like 20 deg) and slowly ramp it up to 27 over a week? Thanks Link to comment Share on other sites More sharing options...
Stuart Elflett Posted September 20, 2007 Report Share Posted September 20, 2007 Yes, get a heater... well, hang on a mo... what's in the tank??? Actually, even if it's a cold water tank, it's still better to keep it stable, get a heater... if you *want* your temp to vary 'naturally', then it shouldn't drop more than 1-2 degrees at night, max... but generically, keep the tank at a stable temp and everyone will be healthier... Personally, if you have nothing that *needs* 27, set it to 25 - that'll keep it stable with the least amount of electricity used... 25 or 27 is as suitable for most fish, but there is still less dissolved oxygen in the water at 27C... Cheers, Stuart Link to comment Share on other sites More sharing options...
DV. Posted September 20, 2007 Author Report Share Posted September 20, 2007 i only have some corys, a handful of neons and some glass shrimp. i haven't decided on what else yet, they'll be tropical though. 27 deg was just the temp the girl at the LFS told me. I'll get it tomorrow. Should i just set it at 25 stick it in and turn it on when the water's at 25 deg and leave it? Link to comment Share on other sites More sharing options...
michael Posted September 21, 2007 Report Share Posted September 21, 2007 You live in townsville most fish will be ok. In the summer you wont need a heater at all. I do use a heater ATM for my new discus but in another month i will remove it. I never use a heater for any other fish BN angles neons killifish and bettas.

Callatya Posted September 23, 2007 Report Share Posted September 23, 2007 Is it a display tank? You could also consider insulating the tank more so that you lessened the heat loss overnight. I'd lean towards a heater for stabilisation and to keep that temperature within the optimal range for the fish (cories would get a bit sluggish at 20*C, they are designed for warmer temps), but I doubt a heater would even come into play in summer. I heat some tanks over autumn/winter/spring and just unplug over summer, so perhaps that is an option Link to comment Share on other sites More sharing options...
DV. Posted September 23, 2007 Author Report Share Posted September 23, 2007 i put the heater in yesterday. it turned itself of after 10 mins or so, then it turned on for a bit over night and it's been off most of today. Link to comment Share on other sites More sharing options...
