I have a 65gal SIO tank that was setup with dry rock and Caribbean Sea live sand Dec 2022. I used bottle ammonia for fishless cycle. I use RODI water and AF Reef Salt. I'm running Ecotech G6 leds 10hrs a day at 70% and t5 bulbs for mid day 2 hrs. I have SPS & LPS and fish in the tank. And a clam. Nothing is dying but I have a lot of algae EVERYWHERE. I went thru a diatom phase and then came what I belive to be cyano. I do not know if adding zoa frags from a local swap meet caused this, but I had SPS in from January and didn't get any until few weeks after I put zoas in there. I added Chemiclean 2 days ago. Performing water change just now. ANYWHO I posted a video here, before vacuuming what I thought to be cyano and the second half is after vacuum the exact same areas but under the what I thought is cyano is this green/grey algae that didn't vacuum out.
