Hows the temp doin?

[Doug]

And here I thought I had problems trying to keep mine up at 79. I have to cover it to keep the heat in. :D :D

How long is this good for? An hour, 2 hours?

What about those blue coolant paks or whatever they are called that are used in coolers? Would they last longer?

Hey Patrick, and others, here is a great cooling trick I learned last summer during the heat wave when I didn't have any canopy fans.

Take two empty 2L pop bottles, remove the labels and fill them with water until they are almost full (leave some room). Cap them and put them in your freezer overnight to make a big 2L popsicle. Now when you have high tank temps just float one of the frozen bottles in the tank to help lower the temp. :cool:

With this method you are not melting fresh water in the tank. Also, by having two bottles, you can rotate them, one floating, one freezing. [img]smile.gif[/img]

I found that they would help control the temp for about 2-3 hours, which is usually all you need during the peak lighting hours.

Not sure about other solutions, but with the 2L bottles being so thick, I would think they would cool longer than a thin ice pack?

<font size="2" face="Verdana, Helvetica, sans-serif">Was just searching the net for ice replacement/coolants. This graph looks interesting. I don't know how big their "bag of ice" is though.

In terms of the small size of ice packs. I was just thinking of opening up the packs and filling the 2L bottle with the coolant. This should make it last longer than 2L bottle of water.

My tank peaked at 83.9F with the MH on for 7 hours. Both canopy fans have been running at their full 12V flow, as opposed to the normal half speed (6V) that I usually run them at when the MH is on.

Normal temp is 79F at night 81F during the day with the MH on, so only 2 degrees above normal. Good news is the temp swing has caused my Bangaiis to spawn again! LOL

Room temp reached 88F by late evening.

Canopy fans are doing their job perfectly! I'm really happy that I added them. :D

Damn it was a hot one yesterday. Outside thermometer read 33C (91F) in the shade!

Hi ... just my $0.02 ... "techni-ice" and/or gel packs may last longer and that's great, but what is that stuff? If a pop bottle with frozen water leaks some "coolant" into my tank, it's only fresh water so no catastrophe (presumably). Just be very careful when using the other stuff. I think if it were my tank, I'd just stick with frozen water. Too many things can/eventually do go wrong, why chance leaking some petrochemical (or whatever it is) into the tank?

Ditto, Murphy's law seems to hold very well for reef tanks. "If it can happen it will happen". Sticking with plain old water would be my choice.
