Heater failed while I’m on holidays

[Luan B.]

So as the title says my heater failed while I’m on holidays, it was keeping 22degrees for a few days and now completely failed, currently sitting at 18 degrees and I’ll be home tomorrow, note that in Ireland atm is freezing cold and my house heater is off… just wondering if anyone has any experience with anything surviving for a couple days at this temperature.

*no one can get into the house to change the heater for me

Not good.

I can say, I've had coral dip into low 70's/high 6o's and survive.
Fish would be fine at those temps also.

But, your talking freezing temps and house is shut off, way different. This all depends on how cold your house will get.
If your house dips to sub 0C, your pipes will freeze. Your tank will be way too cold to sustain a reef tank.

Edit:
If that temp log you posted is your tank, you are already at that cusp of survivability. 18 celcius is 64 Fahrenheit. That is already pushing it. Someone needs to intervene now.

Not sure why you would leave your house heat off if it's freezing . Maybe the heater hasn't failed, maybe the house is just too cold for it to keep up. Either way it's sound likely that you'll loose livestock.

It looks to me like the heater was working but the house temperature was maybe dropping and the heater couldn't keep up. Not sure why would you leave town and turn off your heat in freezing temperatures? Whatever the case, the fish may or may not live depending on how fast you get to them -- but the coral are likely not going to.

On the flip side, I wonder if the colder temps will slow metabolism and allow the fish to survive until tomorrow.

As @exnisstech has already mentioned, it may be that the heater is unable to keep up with the demands of the tank. But we can't be sure until we know how many watts the heater is, total water volume of the tank and the ambient setting of the house thermostat.

Maybe not like freezing temperatures in America, when I left was around 5 Celsius outside and my house is pretty well insulated and attached to other houses… we just got a cold wave and the temperature dropped to -2 but inside should be more than 17 Celsius…

Thanks for all messages I’ll reply to this post with the damage when I get home.

Sorry, freezing temps for Ireland, not like in America, my house without the heater on should be around 17 Celsius even if is 0 degrees outside

17 Celsius is too cold. They won't live.
Maybe a fish or 2 but if others die your going to get lots of ammonia and the living will suffer.

Sorry to hear that. This hobby can hand out some punishing times every now and then. I hope the damage isn’t too bad.
