What exactly is this? It is mainIy centered on this piece of rock but i think i am starting to see it in my DT. This happens to be the same rock i put the shrimp on to spike off my cycle. I think there is actually 2 different types of algae in the picture the one is on the glass and the other one is on the rock. \r\n\r\nMy parameters at the moment are ammonia 0ppm, Nitrite 0ppm, Nitrate 5-10ppm, and ph is somewhere 8.2 range.\r\n\r\nAlso i have been looking around and i cant find Cheato anywhere any ideas on where i can find some?
