75 gallon reef with 20L Sump/Refugium

The growth is only in display and sump is clean. This stuff does blow off rock easily but clogs sock quickly.

Corals are doing great though! Running a carbon reactor and GFO in a bag.

KH 8.0
CA 420
Nitrate was under 5
Temp 77

Reverse lighting cycle with 3 ATI blue plus & 1 actinic for 7 hours

Looks bacterial. Typical for newly set up dry rock tanks.

It is a new set up, going into its 3rd month with dry rock.

Does it eventually die back? I'd rather not have to treat. Much rather have patience with the new tank.

It will in time. One of the first stages of the "uglies".

Did you cure your dry rock before placing in your DT? Or just placed it in there and added water?

Looks similar to Chrysophytes.

Just added rock & water thinking I could cure in display. Added some cured rock from nano thinking it would help but the cured rock is in the fuge below.

The nano cracked in my move so had to rush a little more than I wanted.

I agree @Tahoe61 that it could be Chrysophytes. If so, dry rock is taken from dry land and cleaned before sale. the cleaning process doesn't remove all impurities that have settled or absorbed into the rock over time. Silicates are one. If Chrysophytes, they will consume the silicates unit the supply is gone.

Will take time to disappear.
