hmmm... the heck with stability, prodibio start up, and live sand. we'll just package urine and sell it...:razz:

I always knew Calgary had the advantage over us in the marine hobby.

Seriously, maybe that store just told you that because one of their staff was caught urinating in the tanks instead of running to the bathroom.

As far as I remember, cycling of the tank is to get all the parameters to stabalize, and start bacteria growth. Isn't urine sterile?

http://en.wikipedia.org/wiki/Urine

almost. not when it leaves the body though.. if you would have read one more paragraph from the link you posted you would have seen this

"Urine is sterile until it reaches the urethra where the epithelial cells lining the urethra are colonized by facultatively anaerobic Gram negative rods and cocci.[4] Subsequent to elimination from the body, urine can acquire strong odors due to bacterial action"

I think you'd be better off with the raw shrimp idea but hey, what do I know? I've never peed in a fishtank... yet...

In my tank I'd be more worried of my Tusk fish chowing down on my little weenie!

:rofl:

LOL well if pee starts the cycle what can we do to seed it... LOL I'm not even going to say it
