Tank tempature

I'e checked the probe and compared it, it reads accurately.

I think you need to get a second thermometer/probe to check and see if its correct. If its correct, then Its a pump issue. What brand and size are the pumps that you are using?

 

[cjohnson2]

I have a mag 12 and mag 9.5

 

[mtraylor]

The mags give off heat, but I couldn't image more than say 1/2 degree change for exchange of heat. If they were operating and rubbing magnet it could be allot more. The first thing I would do is get a second reference for temp. Most likely that is what it is.

I only have the one temp probe.

The room temp is 70. The thermostat is in the same room.

Before doing anything else, I'd suggest you pick up a cheap glass thermometer from a local pet store or online and verify that the probe isn't faulty or out of calibration.

I just don't see how a pump can generate enough heat to keep 120g of water a whopping 12 degrees above ambient room temperature. Probe would be my first suspicion and the very first thing I'd investigate before taking other equipment apart.

The fastest thing to do is fill a glass of water up with tap water or tank water. Place the probe in the water. Check it in the morning and see what the reading is. By that time, the water will be at ambient temperature. You will know what its supposed to be. ITs a quick reference point. Not super accurate, but yours is so far off I'm sure you will know if its working.

Even if your tank is at 82 it's really not a cause for concern. Many reefs around the world are that temp and warmer. I ran my tank at 82-83 for years with no problems. Fish and coral did fine.

Maybe unplug your skimmer overnite too. You can live without it for a day, I would think. Knocks off one variable, I know the return is more critical.

 

[JOKER]

I would say the mag pump is the heat source. When I ran one my heaters barely ever came on. Also if you have a ball valve restricting it make worse.

 

[wangspeed]

I would bet the Mags. Turning off the skimmer for a day is a good test. Fans will also drop the temp quite a bit.

If you don't want a chiller maybe fans.

I installed a temperature controller in a waterproof box. One side controls the heater and the other, a 20" fan. It keeps the tank cook, but has to run for a while to get the temp down. Realize a fan blowing on the tank will accelerate evaporation.

 

[Ranjib]

Couple of fans will easily bring down the temperature by couple of degrees at least. 82 is not very high , so don’t panic. If you do take the fan route, make sure your ato is setup, as fans will increase evaporation .

I got a new probe, the new one reads its 73 degrees in the tank. I'm currently slowly warming it back up to normal.

The weird part is the temp probe read perfectly fine at 115 degrees when comparing it to a candy thermometer. Aparently it wouldn't read lower temps correctly.

Do I want to ask what thermometers you used when calibrating the new probe?

Do the mag pumps get warm if they need to be cleaned? They have been running for about 4 month
