Ok,so I’ve been surprised with two poor goldfish from our local fair with nowhere to put them. I have bought a new 300 litre tank that will be delivered tomorrow. The fish are currently in the biggest plastic container I have, and am doing water changes everyday. I know about tank cycling, but I’m not sure how to quickly (I’m talking ASAP) cycle this new tank so I can get the fish out of the crappy plastic box. I have a 50 litre tank already, that is well established and has two filters running in it. My plan is to move one filter over to the new tank, but neither of them are particularly powerful. Would I be better putting the media from it, into the new filter? Its a Fluval but not sure of model off the top of my head. Will I have have to add ammonia to it before hand? I have the API testing kit so am able to test the water as needed. In a nutshell, I know the basics, but I don’t know the best way to go about this.
