Cheap Chiller!!

[Fatman]

I dont know why I have not posted this yet. But my tank was getting way to hot with the lights on for more than 6 hours, so I decided to do my "chiller" idea and it works pretty well.
2 of these lower my tank 3 to 4 degrees if put together.

Basically fill a 2 liter bottle of gatorade (or coke) with water and freeze it!

Thats it!

Make sure the water from the inside doesnt leak into the tank. I usually place it in the sump and works pretty well.

Been doing this for 8 months now with no problems.

Just out of curiosity, how often are you having to change your *chillers*? I'd think 80F water flowing around that would melt them down pretty quickly...

Amazing what the simplest ideas can accomplish with some determination.

I have 2

and they take about 30 mins to fully melt, but since they drop the water 2 to 3 degrees it takes another 4 to 5 hours max for the water to come back up, and when i put them in the lights are only going to be on another 2 to 3 hours so its usually ok.

my light schedule is 1 to 9, i get home at 5 , throw the chillers in (only if i have to mind you), then take em out whenever i get around to it.

Also the temp swings (of 3 and even 5 degrees) really dont seem to affect anything in the tank at all. If theres an EXTREME swim usually 7+ degrees negative the hippo tang (aka dory) will usually break out in ich and well, garlic time all over again.

what kinda lights you running

what kinda lights you running

MH 150W x 2 and 2 actinics PCs.

Obviously the MH are the major heat source.
I noticed a 1degree rise when I dropped the 2 powerheads in it.
