View Full Version : Cycle Complete...?

After 4 weeks, ammonia levels have finally stayed at 0 for a few days now,
without doing water changes. Nitrites were at 0, until now -- they're hovering
around .25. Is that normal? Should I expect nitrites also to be at 0, and
continuing to change the water until that happens? I have found it takes half
as much new water to get them to 0 as it did to get the ammonia down.
Thanks!

Someone correct me if I'm wrong, but I think how the cycle works is first
your Amonia will peek, then drop down. When the Amonia drops to zero, the
Nitrite levels will go begin to rise. Finally, Nitrites will drop and your
Nitrates will rise.
Sounds like you're well on your way to finishing the cycle. Nitrites are
the dangerous, so monitor the levels closely and continue to do partial
water changes to keep it low. When your Nitrite levels drop down to zero,
your cycle will be complete.

my LFS told me NOT to change water during the cycle... said it defeats
the purpose

Changing the water during a the cycling process extends the time required to
complete the cycle. It also reduces the concentrations of toxic components
during cycling to ease the stress on your fish.
Those toxic components (ammonia and nitrite) are actually the foods for the
bacteria needed to cycle the tank. Doing a water change reduces the
concentration of food and therefore influences the rate at which the
bacteria can populate the tank. More water changes = less food = slow
growth = longer cycling time.
So performing water changes during the cycling process is an option so long
as you understand the impact those changes make to your goals.

That makes sense... THANKS!
