RyanR, the nitrogen cycle can take anywhere between 2 and 6 weeks, it all depends on the curedness of the rock in my opinion...Its not a quick thing, so, patience is needed...Spend the time while its cycling to read, reasearch etc etc...it will put you in good stead for when the tank is ready...RyanR;1674489; said:Aprox how long does it take for a tank to cycle when you use RO water to start, and add 50 pounds of live rock, and 30 pounds of live sand?
is this the fastest way?
Thanks
