As some might know, I recently got a 209G tank and last Tuesday, put salt in the water and added 45 pounds of live rock. I intended on getting around 90 pounds to cycle, but our distributer only sent 3 boxes and I bought one. Since I figured that 45 pounds of live rock would not cycle a 209 very well, I added 3 2 inch Silver Scats and a Gold Domino Damsel (2 inches). Well, I did water tests every day for the past week and ammonia never went past .25ppm. Today I tested and ammonia was zero but nitrite was around .5-1. So basically the cycle is starting to wrap up, but I am very uncertain that it would have not cycled completly. I intend on adding many current fish (upgrading from a 55), and would die if any of them died. If I add some of the current stock when nitrites are zero will there be much of an ammonia spike after a new fish is added? The current stock that will be going in after nitrite is zero is: my 3ft Zebra Moray, 3 inch Niger Trigger, 5 inch Volitans Lion. I will also be adding a 4 inch White tail Trigger and am contemplating the Zebra Moray we have had in our store for 5 months. I know it is a bit of a heavy load once the fish reach adulthood, but the wet dry is 4ft long itself, and will be adding a protien skimmer, purigen, and some carbon. So to sum it up, will there be an ammonia spike after I add a new fish? If there is a chance, I will get the White tail and Moray from my store, and try them before adding my munchkins!
