When is it safe to remove media?
I have a tank that is just about cycled. The NitrItes have been spiked for 4 days now. I have an established tank also that has a bio wheel filter and an aqua clear 50. The Aqua Clear 50 has two sponge media and 1 bio media in it. When would it be safe to remove one of the sponge media in the established tank to transfer to the cycling tank (to quicken it)? The established tank has been cycled for only a week now. That is why I'm kinda afraid to remove the media (even thou there are two) I have an extra sponge to replace the one that I remove.
I'm just asking because my local fish store just got my figure 8 puffer in today and I would like my cycling tank to cycle a bit faster since they're holding him for me at the moment.
