Help! Can I seed a heated aquarium with media from a goldfish aquarium?
Iím one week in to a fishless cycle. Iíve looked in to how to speed it up and seeding seems the obvious choice. I have access to a very well established gold fish aquarium and taking some gravel from there is fine, but Iím intending to have tropical fish. So can I use media from a cold water tank to Ďseedí a tropical tank?
Iíve tried to search for the answer online but nothing comes up.
