So I read the article on the fishless cycle but unfortunately I am a complete idiot and I don't exactly understand it all in like a followable way. I'm trying to set up my 2.5 gal tank (Please don't give me crap about it, it's the best I can afford right now. My family is SUPER tight on $$$) for my 3rd and final betta fish. Here's what I have from my previous experiences with Bettas:
-2.5gal tank
-1gal tank
-Marina heater
-AQUA Expert aquarium air pump 600
-Seachem Prime (water conditioner)
-Betta Bits(betta food)
-castle decor
I also have 2 fake plants but I'm going to leave them out because my 2 previous bettas never used them and I've heard they rip fins And I don't want that to happen. When I get a job I'll get real plants or silk ones and then hopefully a bigger tank. So my question is can anybody post like step by step instructions on how to do a fishless cycle? Kinda in a school project format with mostly exact measurements? I know it's a chore but It's kinda how I can set things up the best and I'm trying to at least keep this 3rd betta alive and happy longer than the other 2. Anything is appreciated. Right now the tank is sitting on my desk away from sunlight, no lid(doesn't have one), and completely empty of water. I also cleaned it today to get rid of anything the last dead one had. I'm not planning to get the 3rd betta until I'm positive the tank is ready.
Oh and how often does the cycle need to be done and how can I maintain the water condition to stay where it's at for mr Betta?
