HI All! 1st "real" post in a while. I'll jump right into it...

I have a well established tropical tank but I want to Pick up a Ryukin Goldfish.

Of course I'm going to hook up an additional filter in my tropical tank to cycle for the future Goldfish buddy.

Will taking the Media from warm water tropical to the Cold water Goldfish tank negatively impact the Beneficial Bacteria in any way?

Good morning,

No. The temperature difference should not harm the beneficial bacteria.

Ken,

Did you mean to say it should NOT harm the BB?

I believe the only affect the temp difference will have is to slow the rate of growth of the BB colony.

Correct me if I'm wrong and missing something.

Thanks Lyle...typo Oops!

You are correct about the growth rate being slower in cooler waters but it will not harm the beneficial bacteria.

I tore a 29 gallon down once and packed the 78 degree filter media in a bag with aquarium water. I took it all to a buddy but he decided that tank was too big for where he wanted to put it. The tank and media sat in my trunk for nearly two days in 40 degree weather. I set the tank back up at in my basement to cull 6 full grown head and tailight tetras as well as a 5" pleco until I could rehome them. The filter media didn't miss a step.

Thanks guys, ^ I think that's what this project is (a 29 gal.) but I'm not too sure, can't find a tape measure...
