Water temp

[Freddykruger]

I have a 65 gal tank with blackmoor goldfish and the water temp has been increasing what can I do to lower the temp? I'm having my wife unplug the heater.

What sort of temperatures are you talking, you can simply just do water changes with cold water. Unplugging what heater the room heater or the tank heater

 

[Freddykruger]

The tank heater, it is set for 68 degrees. My cold water out of my sinks are coming out warm also.

So unplugging it won't make any difference as soon as the water is above 68 degrees the thermostat switches the heater off. How warm is your tank and how warm is the tap water.

Atm the tank was bout 76 the tap is bout 80

76-80° is nothing to a healthy goldfish. They can survive in water over 90° and under 40°. They are temperate fish and do okay in a variety of temperatures so long as the changes aren't sudden. Fancies are a bit more sensitive but should still do absolutely fine at 80°. Just ensure there is a little water movement and/or aeration and he should be fine. The heater is not needed at all.

If you see him struggling such as surface piping or bottom sitting (which I have never seen with a goldie at that temp) you can float some frozen bottles of water in the tank or place a fan to blow at the surface.

76 should be fine for Black Moors just put an extra air stone or two into the tank

 

[Freddykruger]

Ok I will do that

And if there is one open the lid to make veporation (way water cools down) easier.

As mentioned above, goldfish are fine in cold or warm water. In fact most common goldfish sold in pet shops come from tropical Indonesia where the water is 30C (86F) and sometimes higher. And a lot of the real fancy goldfish come from the warmer parts of China.

In Australia people keep goldfish in unheated tanks and ponds and the water temperature drops to just above freezing in winter, and over 30C in summer.

One of the members that use to be here @Deanasue bred goldfish in Texas and they were fine there.

An average house temperature that is comfortable for people is fine for goldfish.

If the water is warm, increase aeration/ surface turbulence to maximise the oxygen in the water.

We often hear of hobbyists that unplug heaters when warm weather arrives and I often wonder why. If/when the room temperature gets above the operating set temperature of the heater, the heater never comes on anyway, so why unplug it?
In any case, as previously mentioned, goldfish (*like many other fish) do well in a much wider temperature range than most folks think of. Also as mentioned, always best that temperature swings are gradual so as not to shock fish. Also as mentioned, warm water holds less oxygen, so increased surface turbulence or an air stone may be beneficial.

(*There are exceptions to almost every rule but many, many species of tropical fish can do just fine in a wide range of water temperatures. Often, what we would consider 'comfortable room temperature' is fine for many species.)

Heaters have been known to fail, and cook fish*...I unplug mine in the summertime

*Not literally, of course
