I am in the middle of the cycle for my very first sw tank. And I just noticed this algae sprouting on live rock and on some dry rock. Is this run of the mill green algae because of the cycle or something more sinister? Params: Mg- ? Alk -? Sal- 1.026 NH3- 0.75 NO2 - 4ppm NO3 - ~30ppm I was running lights for a while during the beginning of the cycle. For 5 days there has been no more than 3hrs of light per day. I will be killing all light until the right time comes..
