Nancymacc Posted May 23, 2017 Share Posted May 23, 2017 I have a 24g cube w/ AI Prime HD light. I am trying to determine if I will need something to keep it cool in the summer? We have room ACs, but it can get fairly warm in the house. Just want to get a feel for people's experience so I can be prepared and plan ahead. Are fans typically enough for a small open top tank> Quote Link to comment Share on other sites More sharing options...
Exodus Posted May 23, 2017 Share Posted May 23, 2017 LEDS do not give off much heat, though that can be variable how close to the water they are, as well you have to consider what equipment is in the tank generating heat. The room in which the tank resides has a much larger impact on the overall temperature of the tank itself. Get a temp probe and compare it to the room temp, you will probably see a pattern, figure that out and keep the room at a reasonable temperature that doesn't push you over 79 degrees. I use T5's now (used LEDS 6 years) and have to ensure my temp stays at 72 or below to keep the tank at 77. 1 Quote Link to comment Share on other sites More sharing options...
air561 Posted May 23, 2017 Share Posted May 23, 2017 My system hit 89° today. So far nothing dead or dying, although my Sinularia is drooping. I've been freaking out since I noticed, floating frozen water bottles, set up a big fan, opened the sump doors and turned off most of the lights. First hot day with 6 T-5's and duel 250W halides. I had no idea it would get THAT hot. I'm might get rid of the halides and go LEDs.Sent from my SM-G900P using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
TheClark Posted May 23, 2017 Share Posted May 23, 2017 Likely you won't need anything, especially if you run a heat pump or AC in the summer. 1 Quote Link to comment Share on other sites More sharing options...
Jeremevans Posted May 23, 2017 Share Posted May 23, 2017 I run LEDs and heat is not an issue. I do have AC that keep the house cool though. 1 Quote Link to comment Share on other sites More sharing options...
Willapa Posted May 23, 2017 Share Posted May 23, 2017 Evaporative cooling works amazingly well on a smaller tank of your size. I don't have AC and my old tank would cool down 2-3 degrees in a half hour with just a small 3.5" computer case fan. I think folks use these to ventilate light hoods as well. I just laid the fan on top of my mesh cover blowing down and hooked it up to the Apex. Just need to make sure it doesn't start fighting your heater.Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Sasquatch Posted May 23, 2017 Share Posted May 23, 2017 Get a small computer fan to blow the surface if you are worried about heat. I even wired one into my lights before and hung it just over the water 2 Quote Link to comment Share on other sites More sharing options...
Nancymacc Posted May 24, 2017 Author Share Posted May 24, 2017 I went ahead and ordered a 5 little fan unit and a controller for heating/cooling. Of course the temperature is dropping again, but good to be prepared. Thanks everyone for input. 1 Quote Link to comment Share on other sites More sharing options...

LOL Anything over 80° fish metabolism goes up! They should appear 'high strung' and more hungry. Stressful to say the least. Get a chiller. I unplug the heater in the summer, and just rely on a fan pointed at the ATS to keep things cool. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted May 24, 2017 Share Posted May 24, 2017 I don't run a chiller, although I have one, because I keep my AC at 74. I have to run a heater all year. When I lived in an APT with no AC, I had to use a chiller for a few weeks a year to keep the tank temp down. Fans can do so much, but when it is 104F outside for 2-3 days... well. I vote chiller. 1 Quote Link to comment Share on other sites More sharing options...

LadySaber Posted May 26, 2017 Share Posted May 26, 2017 frozen water bottles and a fan blowing over the surface works for all my tanks 1 Quote Link to comment Share on other sites More sharing options...
