View Full Version : New FOWLR tank- when can I add fish?

09-21-2012, 06:03 PM
I started up a new tank a couple weeks ago- all my levels are good-pH is good, salinities good, no ammonia, no nitrite, and very low traces of nitrate. I used live rock (about 15 lbs or so for a 29 gallon tank-i know not much but i have other decor pieces) and couple inches of live sand. when can I add fish? Im planning on starting out with a clown fish and am hoping for a puffer when im ready. how do I know when this "cycle" is done and when I'm safe to add fish.

Did the cycle ever start? Did you notice an ammonia spike followed by a nitrite spike and then finally nitrates? If so then I would say you are safe.

You can also add bacteria from a bottle, when you add the fish.
