Hey guys,
I have a 120 gallon mixed reef with a 40 gallon sump, running for 2 years.
Everything has been great for the last 8 months.
I recently added 3 small (about fist sized) pieces of marco rock to the tank and a new frag rack.
Since these were added, I am starting to see a fine film of brown on the rocks and rack. (it easily blows off with a turkey baster).
The day after a normal 10% water change, there is a lot more of it.
Nitrates:0
kh: 8.9
ph: 8.3
Phosphates: 0 or .03
salinity: 1.026
cal: 435
mag: 1430
Cause for concern? And how do I get rid of it?
Thanks for any help!
