Hi all who reads this! I have a 30 gal tank which is fully cycled with good water parameters. I have decided to use my old 5 gal tank to breed shrimp. I have put the sponge filter that I will be putting in the 5 gal in my 30 gal tank. I am hoping that this will soak up some of that lovely bacteria. Just wanting a second opinion really. I will keep the filter in my 30 gal for about a week, then I’m hoping that when I move this to my 5 gal tank, it will cycle quicker. Any other suggestions?
