I can't belive there was only one recommendation for Bio-Spira! lol i used it on my 29 gal community way back when and it worked like a charm. But make sure its bio-spira not "cycle" or any other lame brand. Bio-spira is all natural beneficial bacteria in a bag:headbang2: and perfect for starting up a nice culture! :nilly: thats your best bet until you can get that 20Lalong with your water changes of course!:shark:
Wow! you are my first person that says this works I have only seen posts that say its hit or miss
