My tank is hitting 35*c!

[whiteymoza]

Ok I went into my room just now and just by chance I looked at the thermometer and noticed it was sitting just about 35*c th windows were on and a fan circulating the air (tank temperature is usualy set at 28*c is there a short term (2month) method of keeping the temperature constand and avoiding drastic day-night temperature fluctuations.. Most of the fish in there are bristlenoses. Im very worried is this going to be harmful?

Never mind the day/night fluctuations, it isn't a problem, fish will take pretty big swings in their stride as long as it's within their acceptable temperature range (typically from 20 to 30 celsius although with considerable fudge factor at both extremes), but 35C is borderline lethal for a great many species.

I strongly recommend lowering the daytime temperature of that tank. Turn off lights & heater (but not pumps!), remove any cover glass or canopy you might have, place a fan so it blows across the surface to increase evaporation, if need be freeze plastic pop-bottles filled with water and put in the tank.

My friend's Zebra breeding tank shot up to 98f the other day. He's had to buy a fan to try to keep it down.

i went ahead and removed my heater, seeing as the Weather is pretty hot even in the night time, so i dont need it. Dont worry, the room stays at 26 at night anyway, the closest to 25 i can get

With soaring temperatures the other thing is to remember the fact that the higher the temperature there is a reduction in the amount of dissolved oxygen.
Today the temperature in my fish house touched 92°F, as well as turning my fan heater to blow cool air only; I increased the airflow in 90% of my tanks. (The other 10% really didnâ??t need it).

I'm having the same problem, too. I find it nice at some point to just take all the heaters out of the tanks. I've got them in storage until the Autumn unless something drastic happens. I have a fan on the worst tank. I find airstones help especially with Corydora spp. and Chaetostoma sp. They seem to have less labored breathing when the temperatures climb. This is a slight pain, but if you have the time, an extra small water change during the week doesn't seem to hurt either, from my limited experience. I've got Ian's suggested set up going now on the Chaetostoma sp. tank: the cooler with ice and the air lines running through the ice. It seems to cool down the water an extra little bit.

Just take out the heaters and just let the tanks keep their temperature from the room temperature.

Hi

I was searching the forums for another reference on a totally different subject from a few years ago, and stumbled onto this

Phew!

Here in northern spain last year we hit more than 40 degrees on a couple of occasions, and more than 35 regularly. I lost a few fish from my community before coming up with an answer. I bought one of those mini-fridges, the kind that you can fit a couple of beer cans and a sandwich in. I drilled a hole in each side just big enough for my water pipe from the filter, and coiled about 1m of it inside the fridge. The fridge sits between the filter and the inflow for the tank, so the water leaves the tank, passes through the filter, then the fridge and finally into the tank. The fridge drops the water temp by a couple of degrees only, but seems to be sufficient to have prevented any more deaths during the hottest periods last year, and is doing sterling work so far this year, it is also a lot more gentle than the frozen bottle method, which crashes the temp redically and has killed a couple of my cichlids and knife fish in the past...

A bit less money than the ones they <a href='http://www.drsfostersmith.com/Product/P ... 004+113768' target='_blank'>sell</a> for reef tanks, too.
