So I recently got a new 30 gallon tank for my ryukin goldfish and an AC 70 filter. I already have an established 20 gal with an AC 50 filter. I moved all the AC 50 media to the new AC 70 to give it a quick cycle. I also put the new bio bag that came with the AC 70 in it on top of the established one. Now all I have in the AC 50 is some floss kind of media.
My question is, is my 20 gal tank ok for awhile with only the floss? Or do I need to put a bio bag back into AC 50?
Thanks!
