Hello all,
I am a experienced reefer that recently suffered a tank crash. I restarted my system fresh with new dry rock and marine pure bio block. I went through the stages of cycling never got diatoms but got some sort of brownish green Matt algae.
My question my rock now appears to have a black look to it. I do weekly water changes and have 2 mp10s which create strong flow. The tank is bare bottom and when I blow the rock off I get some junk off but the blackish look stays. Anyone have any idea what this is? I don’t seem to remember having this problem on past tanks.
