We’re upgrading from a 10g to a 55g soon. I’ve done a lot of reading about recommended equipment, plants, fish, etc. I’m now looking into the actual process of moving the fish over and have a question. I’ve read it can really help to cycle the new tank if you bring over the old filter for awhile as well as any inks decorations and substrate from the old tank. We have some natural colored gravel in the 10g, but I’d like to put in some black Eco Complete. Is there a way to take advantage of the old substrate without ruining the look of the new tank? I was thinking about putting the old stuff in some kind of dish temporarily so that it could be removed once the new tank has cycled. Does that sound reasonable, or should I just accept the old filter and decorations as being enough to speed things along?
