emergency help
 

i got home from work and my tank is at 86 degrees, heater is set at 76-79
its never done this my acan looks dead shrunk right up help plz what would cause this

and for a control mesure my FW tank temp is normal so its not my house heat affecting it

think i found the culprit...... broken heater contact must be stuck closed keeping the heater on so im buying a new one already unplugged so ill switch my WC heater 75w to my freshwater and my FW 100w to the SW i know its not enough but it will have to do till tomorrow morning

Depending on your tank size, you could run an airstone or run a fan across the surface of your water to help bring the temp down quickly.
You don't happen to have some new salt water sitting at room temperature you could add to your system, do you?
A bag of ice cubes floating in the sump could help too.

Bad luck.

i do have wc water warmed to what tank was before the heater broke
shoudl. i add slowly?

or should i just go through the wc as planed tonight

Anything lower than the current tank temperature would help to bring down the higher temperature. Depending on what percentage water change you have available, I wouldn't be concerned about slowly or not. 10 - 20% I would change quickly - 50% I would do over a half hour or less.

its a 46 bow so i have about 10 gallons ready :) TY

Good idea to keep some 2l pop bottles frozen with water, just in case. can float them in tank to cool water. Even pop bottles filled with cold tap water will help in emergency. My heater did that once, I caught it at 94F Shrimps and all LPS died. fish and Softies survived though

I would cool it down very slowly! quick temp changes are bad for the tank. Add an extra airstone as was mentioned above. Do not feed the fish either for 1-2 days.

When temp comes to apprx what it should be, do a water change
