I bought a new 40 gallon tank today. I moved some plants and gravel from my old tank. I also moved my filter and about 5 gallons of water from my old tank to the new one. How long do I need to wait to put fish in? I read that the water needs to be able to remove 5 ppm of amonia in 24 hours. I am just wondering how much this process will be sped up by using things from the old tank or if that even works.
Thank you in advance for any replies.
