i agree with mike 100%.
well, now i dont have to repeat all this, hehe,. give this a read
Newbies, a little something on cycling/breaking in a new reef tank.. i do go into shrimp/LR-cured and uncured. as the thread goes on.
deli shrimps are fine to use, i perfer LR only because of the diversity of life and the amount of microbes that break down decaying for the carbons which inturn releases ammonia(NH3) and starts up the nitrogen cycle. but there are plenty around to do the job with a deli shrimp.
