Need help lowering aquarium temp workout chiller

I have a 60 gallon tank that I can't keep lower than 79 degrees. Some days it gets to 80 degrees. I have no heater and its not in the sun. I don't understand why its so hot all the time. Can someone help me figure out how to lower and keep the temp low?! I want to get neons and corys but they like temps around 70-74. I don't want to buy any fish yet because I can't get the temp right. I currently only have a mystery snail. Ive had fish tanks for a while, and I have never had this problem. I have a canister filter and I HOB filter run 24/7. I do have extremely bright lights to help my plants grow. I keep the lights on for about 10 hours a day. Could that be the issue?

 

It could be your lighting and that would be my guess, you didn't mention what type they are. I had the same problem with the 29 gal tank in my bedroom. In the day it was too warm and at night it dropped too low because my wife leaves the window open. I remedied the problem by purchasing a titanium heater with a good controller and very accurate thermostat. Glass heaters aren't very reliable IMO...titanium heaters have really good thermostats. I can set the temp in my 75 gal and I get exactly what is says at the controller. Something you might want to look into, I will never buy another glass heater. The titanium's aren't really that much more expensive considering all the hassle. Good luck!

 

What's the room temp?

 

I turn the ac off when I leave the house. I work all day so that's probably a big part of it. Do you think it would affect my fish if I had the lights on for a few hours, then turned them off during the hotest part of the day, then turned them back on for a few more hours? I have a timer so I can set it to do whatever I want. I just don't know how it will affect my fish. I don't know what kind of lights I have. I know they are led. They don't really give off that much heat.

 

The break in the lighting would be fine!

What's the air temp when you're home, and how warm does it get while you're away? A 60 gal won't change temps quickly with the air temp, but if it's always relatively warm, then that might be the issue.

 

I set it on 80 when I leave.

 

And when you're home, what's the air temp?

 

Like 77. My house never feels hot so idk.

 

Chiller? Need a solution to this problem too. What would a DIY chiller?

 

That's why. If your air temp never goes below 77 F, your tank won't either. With the mechanical fixtures and the light (plus the warmer temps during the day), it makes sense that your tank sits above that.

You can aI'm a fan to blow across the surface of the tank to get it a little cooler (a degree or a few), but if you want your temp in the range listed, you'll need a chiller.

Close all blinds in the room that the tank is in that should help to.

 

I've got cories that do well at 79 to 80 degrees. Get cardinals, they like 80 degrees. The cost of a chiller is a lot, and running it costs a lot, and getting it recharged every few years is a pain. Just find fish that like it warmer.
