Part of the nitrogen cycle. Do you have an ammonia/nitrate/nitrite test kit for saltwater? A must for any saltwater tank. It will let you know what your water parameters are doing so you can safely introduce livestock later on.
Your cycle should be almost done tho... Keep patient! Any serious salt head will tell you the same!
And welcome to the Saltside....prepare to spend many hrs staring into a glass box of water! (and dumping ur wallet right into it...
)
