Water change question

[ssky]

Question about water changes. I have a 45 gallon fowlr tank and I am planning a 5 gallon water changes every two weeks. Question is should I go through the pains of preheating the water to match the display tank or not.

drastic temp swings could kill fish. preheat enless you house holds at about 78* F

Just use a powerhead when you mix. I do 5 out of my 20 gallon every week an the pump heats it up enough. I've never had an issue.

I do have a pond pump in my 20 gallon mixing barrel that i leave running for a few hours to mix and aerate water. I think it should do it

I do 50 gallons on a 300 gallon system and don't heat the water. I use a mag 7 to circulate it overnight, and it's usually hotter than the tank water when i do the change. It doesn't change the temp at all.

Great. Thanks guys for clearing it up. I do have a plan to buy a spare heater later on (still recovering from my initial expenses ). I will be able to use it just in case.

I heat my water but only because I have it being made outside and even in florida we get some cold nights. lol I aim for a few degrees either way, as MrX said, it usually doesnt change the tanks temp much if at all. Especially since you are doing small changes I doubt you will see any change at all.

In Michigan water really gets cold. I think it is around 68-70. I may have to get the reading from my ro water bucket..
