Ele 40 Posted July 29, 2013 Hi my names Eleanor and I am new to this site. I have a question(s) concerning upgrading my aquarium. I have bought a 30 gallon aquarium for my one Ryukin goldfish. She is currently in a 20 and I wanted to give her more space. I also bought a 55/75 Aqueon filter which runs at 400 gph. Anyway, after looking all over the internet I haven't been able to find the answer to my upgrading questions which are: Can I put my new filter on my old aquarium to "prep" it for the new aquarium or will that make all my levels (bacteria, ammonia, nitrate, nitrite, ect.) off? If so could I just soak my new filter cartridges in a bucket of old aquarium water to transfer the beneficial bacteria? I am planning on putting my old water in my new aquarium but my filter cartridges aren't the same size so there isn't really anyway for me to use an old one in my new filter to start the build up of good bacteria. I hope I posted this in the right spot and I hope all of this makes sense! Thank you guys so much! 0 Quote Share this post Link to post Share on other sites
yafashelli 9,540 Posted July 29, 2013 You can move your new filter to your old tank, yes. Also, you can take your old filter, and place it on your new tank, so your friend can enjoy all that extra space. Regarding the old tank water, just put fresh water in your new tank. Beneficial bacteria is mostly found in your filter media, so there's really not much benefit to moving old water over. Good for you, for giving your fish so much space. Be sure to post pictures! Welcome to Kokos. We're very glad to have you! 0 Quote Share this post Link to post Share on other sites

Mernany 3,708 Posted August 4, 2013 welcome! I just put my old media in my new filter when I moved to the bigger tank. Since the media was too small for the new filter I put new media in there as well. Everything was together in the filter for a couple months and then threw out the old stuff to fit bio max in there instead! I didn't have a cycle bump but I was testing often just in case Sent from my DROID RAZR using Tapatalk 2 0 Quote Share this post Link to post Share on other sites
