Dobby is very curious about the airstone soaking in the tank. I'm glad I have hornwort in the tank to diffuse some of the current for him. I should be good on O2 with the way the filter is splashing, the plants, and the air pump.

It's staying at 80 now. They're all a little upset, because I took the opportunity to remove them and do a 75% change instead of a 50%.

The main problem using an ice pack is the up and down bounce in temperatures. In my opinion, it would be less hazardous to keep the temp steady (although high) rather than have fairly rapid temperature changes as you add ice packs and they melt each day! I have heard of folks putting ice cubes in a colander over their tank and letting the cold water drip into the tank, but it's still hard to regulate the temperature change.

Evaporating water is the way many commercial air conditioners work. One way to semi-of mimic this effect in a fish tank is to have a canister filter's spray bar "drop" water into the tank or, use a HOB filter and don't fill the tank up completely. The evaporation of some of the water as it falls into the tank will have a very slight cooling effect by increasing the evaporation of the water. That's sort of what the airstone is doing for you!

I have a hob filter and the airstone running in opposite corners of the tank. Removing the front part of the hood seemed to give the biggest drop in temperature. The bad news is it's suppose to be even hotter tomorrow.

I agree with DKRST that it is best to not have fluctuating temperatures. For years my tanks all went up to nearly 90F during heat waves, and I never lost a fish. And I did nothing but let the tank run. I now have an air conditioner in the fish room, which keeps it around 80F which is higher than normal (77-78F) but more manageable. My fish room is on the SW corner of the house, and no shade from trees, so it gets very hot in the summer.

Oxygen shortage is a risk with higher temps (warmer water holds less oxygen, so fish have to work harder to get it, which is the opposite of what fish--like humans--should do during heat. The extra circulation, airstones, etc help with this. Leaving the tank uncovered can help by increasing evaportaqion, but make sure the fish are not those that will jump out. Many fish will jump given the opportunity.

Reduce feeding; less food means less energy being used by the fish. Missing alternate days will do no harm to mature fish.

I agree with DKRST and Byron in regards to wanting to avoid fluctuating temps. I should have expanded and been more precise in my post....sorry!

If using the ice bricks etc., I would only do it if someone was home to keep an eye on things. I have used them, but it was only when the temp. was in the 40s* Celsius (100*F) and over, which is what our Aust. summers can reach during the height of summer (those temps. were in the back of my mind at the time). I can honestly say that the tank temp. only dropped 1 - 2 degrees in those instances, it mainly just kept it from getting warmer.

I wouldn't feel very secure with using ice, and the tank dropped enough without it at least. The snails still aren't happy though.

i found this thread under the "Important Topics" stickied thread in this forum awhile back, and have been using the frozen bottle method in my 55 gallon. i live in phoenix, and it was over 100 here today, and will eventually hit 115 later in the summer. i use 1 liter bottles or 1 gallon jugs. fill them about 70% full of water, and freeze them. then lay them in the tank, and they'll float on the surface, and cool the water around it. the smaller the tank, the more you'll have to watch the temps, cuz they'll drop alot faster. i've been doing this for atleast the past month. of course doing this results in temperature flucuations, which others in this thread did not approve of. but it's worked for me so far.

Hey, if it works for you, I certainly don't disapprove!
Thanks for digging out the link.
