I hope everyone’s tanks survived the hot weather. If anyone has any hacks aside from fans and ice packs it would be great to learn them.

I can’t justify the cost of a chiller and the space it would take up for the odd week every year or two it would be needed.

Keeping your heaters up a bit (within reefing tolerances) can help reduce night time swings as the tank cools during the night .
Without adding a source of 'cold' it will be a struggle to cool a tank when the ambient is hotter than desired temperature. It won't matter how much air could be blow across the tank as the air is warmer than tank just now .

Air con unit. Chill the whole room.

A coil of hose into a large plastic bag, then push into the sump (that will squish the air out the bag), then let water trickle through the hose to cool the tank.

It my first hot summer since i started my reef tank, its quite a small tank, 100L, and have seen the temp peak at 28.1C. Lows through the same period have been 25.7C. It appears to be coping and parameters have stayed within norms.

Hermit crabs seam a bit more active and I have a couple of serif snails that havnt moved for a while and may not have made it but fish and corals seem tobe fine.

What are you seeing in you tanks?

I have a usb fan that kicks in when the temp reaches 26.3, fitted it after my temp alarm was going off a while back, works well .
Its going to get hot again so watch out guys .

It's counter intuitive but you can cool water below the ambient air temp by using a fan on the surface.  It takes about 440 BTU to evaporate a litre of water which takes a pretty significant amount of heat out of the tank.  😊

My front room was 29c last night 😴 tank stayed around 27 -27.5 with the fans on it.

Here's the readings from my seneye
