This is the crap that grows on my sand. I think it might be brown cyano but not certain. If I disturb the sand at all it gets so much worse. Some times it is gone for a day or two but just comes right back and worse. NO3 reads 4 and PO4 has always read 0.00 on hanna and red sea kits. But I have some gha growing in low flow area. I have gone months without using any phosphate media and still can't get a reading. I'm thinking that the stuff on the sand and the little gha that I have is giving me undetectable readings.
Thoughts?
