Hello; Yes. The quickest way is to seed a tank with some solid material from a long established tank. This can be pretty much any solid surface. Used filter media, substrate material like gravel or sand, décor and such. I like to add snails from my old tanks as well as they should have bb on their shells. If you know someone with an established tank try to borrow/buy some such material. maybe from a fish shop?Alright. I'll up the water changes to daily until I get a much lower Ammonia level and no more new fish for a while. Is there a way to create/add a BB to an existing tank?
You can also add some live plants to help. there are floating plants that can be thrown in. Some plants can take up a bit of ammonia directly and I feel they may also have bb on their surfaces.
Good luck
