Pouring colder water in tanks.

[WyldFya]

you should always try to refill your tanks with water that is as close to the temp inside the tank as you can get it..that way, no shattered heaters, no shocked fish..

Cold water is a trigger for many fish to breed, and it won't harm them at all. Think about nature. How often is the rain that falls from the sky going to be as warm as tropical water?

Mix hot with cold until it's around the same temperature at the tank water, a little drop (4-5F) is not bad as it's common in nature for the water temperature to vary from hour to hour or season to season. In fact adding cooler water usually triggers most fish to spawn. However, you must add the water slowly (keyword).

Even adding the water quickly won't affect the fish very much. Many petstores add cold water when doing water changes.

Thanks for the info.

And can a 150watt stealth heater burn a fish or a turtle?

The thing about rain in tropical areas is that it's falling through tropical air. Air which is going to be warmer than the water in which the rain is falling.
So, there's little reason to think that rain is going to chill the water significantly particularly when you consider the tiny proportion of water contributed by falling rain in a tropical lake.

Rain is a poor example, but floodwaters might well be considered a valid factor. Indeed there are a number of species which spawn during flood conditions.

Though of course there is no reason to believe that condtions which might initiate spawning are conditions which are pleasant for your fish.

Fish aren't like people, they don't like romantic settings and mood music before breeding. In many instances fish spawn in adverse conditions to ensure their species survive.

Even adding the water quickly won't affect the fish very much. Many petstores add cold water when doing water changes.

There's no reason to consider the practices of pet stores in any way ideal; quite the opposite in many cases.

An ideal temperature for your fish is a steady one. So, try to match water change temperature to that the fish are currently in.

Have you ever felt tropical rain? It isn't that warm. It is warmer than rain in say washington, but in washington the water is colder. Rain is always a considerable amount cooler than the bodies of water that have a maintained temp by the land that insulates it. The practices of many petstores are probably better than those that hobbiest use. How many tanks even on MFK have water changes once a week, constant scraping, constant water changes, and filtered water? Yes their size of tanks are not optimal for life of a fish, but as far as the water goes, any good fish store is leagues above most fish keepers.

i add colder water all the time... had no problems yet

 

[JEAE21]

What about the heater burning issue?

 

[WyldFya]

Heater burning what?

 

[HarleyK]

And can a 150watt stealth heater burn a fish or a turtle?

Yes. Passive fish (e.g. ambush hunters) are more prone to burns than acitive fish (e.g. silver dollars), though. Many people use heater guards or place their heaters in their sump.

Heater burning what?

fish and turtles..
will they learn, once they get burned?

where can I get heater guards for the stealth?
i have a guard on my heater but it seems like it doesn't let the heat distribute throughout the tank..
