Yep. You have an excess of phosphate leaching out of your rock and sand, which is a process that may continue for a while. This can get bad, so I recommend getting a GFO reactor and using 1 jar of Phosban or the like per 50 gallons, changed monthly until your tank has seen the last of the waving fields of green.
