Not sure exactly what this is on my rock work, but it is loose and can be scrubbed off very easily. My nitrates are definitely high (>50 ppm) so I started dosing vinegar to bring them down. My phosphates are also slightly elevated at 0.09 ppm. Any thoughts just from looking at the pictures? I have 3 tangs (blue, white tail, and purple) and none of them seem to be interested at all. Thanks for any help!
