Yep, so long as there's no fish in there. Check the sticky on Fishless Cycling and go over what Rockabillychick was telling you on how to manage that part. I've never done a fishless cycle so I want to make sure you get the right info. I've always used Bio Spira to cycle with.djmodifyd said:no problem......i like gettin things done fast....i hate waiting...but i will for fishy's sake.
so....just leave it and let the ammonia work itself out right? unless it starts getting over 4 ppm?
Good luck!
