My Tank over heated 90+ degrees over night plz help!!
As the title suggests my Saltwater aquarium over heated last night because of a faulty heater running full blast all night the majority of my fish are dead but now i'm just kinda concerned about my corals and anemones i've got sealed ice packs floating in the tank attempting to cool it (i've obviously removed the broken heater) and i swapped some water. The temperature is dropping but will my corals and anemones be alright?
I've cooled the water by about 10-15 degrees now back down to reasonable lvls but please i need advice
the heater was turned all the way down so it shouldn't have kicked on unless the water temp dropped below 70 degrees thats the only reason its in there. i have since removed the heater it looks like the only things to survive were the corals anemones along with three apparently very hardy Pajama Cardinals. I'll call the local reef shop and ask if i need to dip the corals
when it comes to a heater that's going to be used in your tank with fish and corals that im sure all adds up to a pretty penny I would go with the best possible heater you can buy. As fare as the solution to this problem not sure, I dont know if i would of put ice packs in though because now your bring the temp back down that much. So going up 10-15 degrees over night then going back down 10-15 degrees that a lot of stress in a little amount of time. hopefully they will pull through though.
Just put a fan over your tank or your sump to slowly bring the temp back down. Your corals may look stressed for a few days because of the change but most will pull through if they do. You will know within a few days I'm sure as other start to look better
Main thing is to make sure your oxygen levels come back. Make sure you have a power head aimed up at the top of the water for surface breakage. When tanks overheat oxygen is lost- probably why your fish are all dead. The water change helped I'm sure. Also- you will probably need to do a water change in a few days to remove the converted nitrates from the die off so that your corals are not affected from that.
