Caribsea rock ....issue?
Does anyone notice difference coatings on caribsea life rock as in buildup? tanks been running for 2 yrs no issues but the rocks get covered in a deep dark green coating.... not coraline... thats underneath... and it does not appear to be cyano... it comes off by lightly scraping... and it floats away like detritus but comes back in few weeks this is my first use of this rock i always used natural live rock like fiji or etc etc... never had this issue im using microbacter clean to see if it helps
