Cycling A Cold Water Tank - Question?

Hey Everyone,

I am currently cycling an aquarium which will be used to hatch rainbow trout eggs, these eggs are typically hatched around 10 C (50 F), so to achieve this temperature I am using an aquarium chiller.

My question is will the tank cycle quicker at room temperature or does it matter? The tank temperature is currently at 6 C (42 F) because I must acclimate the eggs which are currently in 2 C water.

Is beneficial bacterial growth affected by water temperature?

The hotter the water, the faster it will cycle. Increased temperature speeds up the metabolism of the bacteria.

The bacteria reproduce quickly over 80F.

They're less effective at lower temps, but I see no reason not to cycle warm and then bring the temp down once it's complete.

Great, thanks for the advice. I'll turn the chiller off until the day before the eggs arrive.
