High temp sitting 82!

[Jack biocube 32]

Alright I might catch some flack in this but I’m out of ideas. I noticed some of corals going and got worried. After testing water parameters (all good) I went out and bought a new thermometer. It reads 82 my tank has been holding at 82 for I few days. I don’t know what to do. I’m loosing corals fast now. And need help quick. Fish are healthy but starting to get stressed.

freeze up some bottle water and put them in your sump or tank to bring the temp down. Another suggestion would be to put some fans to blow some cool air at the top of your tank.

Need more tank details

Ice works as a temporary solution but need to correct reason causing problems

That’s about my normal temp on an SPS tank. Well I try to keep it between 81.5-80 during the summer and above 76 during the winter. However my tank use to run 82.5-81.5 during the summer. If I were you I would add a clip on fan to lower the temp by a few degrees. Just make sure you have enough water turbunce and surface agitation to keep water oxygenated and you should be ok.

Also if I’m reading the thermometer it looks like your pushing 86-88 (20 degrees between numbers (2 degrees per line). Possible heater malfunction?

I wouldn't think 82 would be high enough to take out your tank. This is probably not the question you want asked, but are you sure that thermometer is accurate? Maybe the temp is higher?

edit: agreed, it looks like your tank is at 86

Yeah mate, 30C is 86F. Gotta get that temp down asap. Fans, AC, frozen 2liter soda bottles, etc..

Thanks for the tips. Yes my tank is now at 86 now that I look closer. Not sure what details to give or that would be helpful(new to the hobby) tank is 32 biocube and I run an aquatop GH series heater, tank read 82 yesterday but 86 today. Can you tell if a heater malfunctioned or is it just a guessing game?

 

[Dkmoo]

Unplug that heater and see what happens

 

[FishyFishFish]

Where are you? What is the ambient room temp?

Does the heater have a LED on it? If so, is it on or off?

Stick your hand in there and squeeze heater to see if it is hot. If it is then you have some kind of heater issue

86f isnt a reason for your corals dying, look elsewhere. Reefs survive higher temps, and usually death doesn't happen, just bleaching which they can regain. My reef used to get to 88f last summer for a few days, nothing bleached or died.

I would get a decent thermometer that is rated for accuracy. You preferably want to that it rated plus’s or minus half a degree or less. I have seen many hobby thermometers and heaters be off by 4 degrees.
Like others have said 86 should not be a huge issue. I would un plug the heater as it could be intermittently sticking on until it gets hotter than it should, which is pretty common. Get a fan of some sort blowing across the surface of the water. It should be all you need, but will increase evaporation. Older and lower quality pumps can add a lot of heat to a tank, as can some lighting. What is the ambient temperature in the room your tank is in?

Those glass thermometers are highly accurate. It's most likely the Aquatop heater. I had one and it was a point of sale. Unplug the heater and see what happens. You either need some A/C in that space or a new heater ASAP.
