BTW what are you using for lights?

Hi Grizz, I use LEDs for lighting. I'm not sure what the specs on them are. Anthony do you remember?

I scooped out the cyano I could see with a net. I do 20% water changes weekly. I did pickup some corals last week that came from a tank that had cyano in it but he said the rock they were mounted on were clean. Hmmm......
