Cycle question

garcia64 · Dec 8, 2015

So I started cycling my 90g on Sunday with three pieces of pretty large shrimp I also added bio-spira to the tank. Today I check it and ammonia is around .25 and nitrite is between 2 and 5. My question is could my tank really be done with ammonia cycle that fast and should I pull the shrimp out

based on your post, Im wondering if you had all group B rocks, curious which kind you started with

The lfs sells boxes of "live rock" but it was all dried

I'd leave the shrimps in there and let it rot away. Last time I cycled my tank. I took a hand full of frozen shrimps and that stank up the entire apartment and my neighbor's apartment. But it works!

For how long, I don't want to continually add ammonia into my tank I know there is a point of when to stop

I left mine in until it disappeared then did water change after 2 weeks.

The addition of Bio-spira introduces bacteria into your tank which will eat ammonia and will keep the ammonia from spiking just wait till your nitrites go to zero.

Leave shrimp or no

my link does show the stop time and how to test, an ammonia digestion test is the specific stop time. since your rock wasn't live it would be treated as group A rocks, easily outlined there.
