dan, if you have ammo, your tank IS cycling.
niko, give us a little more details, and whatever you do DONT scrub the rock, that is only a LAST resort, as it kills off too much of the good stuff that will help your tank stay stable.
If your tank is young, it is common to have an algae bloom and it can last for as little as a week to a month or more. each tank is unique. if you wait it out, sooner or later the nutrients that the algae is feeding off of will be gone and it will die off.
Have you tested your scource water for phosphates? thaqt could be a problem.
What type of lighting do you have?
cut back on lighting.
Patience is everything in this hobby, dont rush it, you will be ok in time.
Please also post your water parimeters. and as much details to the problem as you can, including your setup and how long the tank has been up and running.
