Aquarium Advice Apprentice
okay, this might sound like a wierd question but I gotta know! can I cycle a new tank without a filter? the reason I ask is because I have a fully established 55 gal already (been running for a year now) and I am going to be putting all my fish in a 20 gal (don't have very many fish). I will be eventually re-setting up the 55 gal in a few months when I can get together all the supplies. so, I started aquascaping and I was planning on using some substrate from my 55 to put in the 20 and I was ofcourse going to use the same water straight from the 55 and also ornaments. I know my 20 will probably go through a mini cycle because I do have new substrate but i was wondering if I can just go ahead and set it up and transer immediately or do I need to let the new one sit and cycle. I don't really have the funds right now to buy a new filter, which is why i need to know if it can cycle without a filter. sorry if this is all over the place but I hope someone can make sense of my post lol. would love any advice you can offer! thank you!
