New Tank Cycle
Hi my friend is in the processing of cycling a 65g saltwater tank. I persuaded him to use a fishless cycle. In testing he has not yet received an ammonia reading. I do not understand. I used only 1 large shrimp in my 75g and received ammonia readings.
He used 2 shrimp, added on Wednesday, and still no reading.
Should he add more shrimp or are we jumping the gun?
Also his setup include about 30lb of live rock. It had some cool things growing on in and it was transported in water from the tank he got it from.
Thanks in advance.
