Temperature

Okay, so my tank is sittin at 81.6 degrees F. I want to bring it down to 77. Its like 36 gallons of water... thinking of putting frozen di water in it as ice cude over a day or too..... anybody know how many gallons of ice its going take????

 

I am not one of the experts on this site - fairly new to the hobby. But I had a similar question a while ago. I was trying to cool down my 90 gallon tank - it was always up at 81 F, and I wanted it around 78 F. I tried using frozen RO/DI water, and I found it a real chore to be constantly adding ice to the tank. So I bought a cheap fan from home depot (cost me about $10) and put in at the top of the tank to blow air along the surface of the water. It cools the tank to about 77 F (and I put it on a timer to be off at night). You may want to think about this route rather than constantly freezing water and adding blocks of ice.

 

I would start with half of one of those big bags of ice. But may I ask why you want to bring it down. 81 is perfectly fine as long as it's stable.

 

Is there any reason in particular to cool it down? 81.6 isn't that hot to me. Is it just a temporary heat spike due to summer weather or something? If everything looks ok in the tank I would be tempted to just let it run its natural course.

 

well i believe it was a heater malfuction because the tank was at 88 degrees... i took out the heater and it dropped and been staying at 81-83. i keep the house around 76. .. i want to start adding more corals and ive been reading that low 80's is okay but thats an extreme
