Looking to ID Algae in Sump

[DKoKoMan]

Hey folks,

I’m looking to identify this weird cream / brown colored stringy snot like algae which has showed up shortly after my chaeto disintegrated. The “nasty stuff” is not present in my display, however is attached to my overflow pipes and in my sump area. I do biweekly WC’s (reef crystals) 30g on my 150g tank and siphon out this stuff on a regular basis in clumps. Looking for any help on how to rid my tanks of this nasty stuff!!!


Salinity: 1.026
Temperature: 80 degrees Fahrenheit
Alkalinity: 8.9 dKh
Calcium: 450 ppm
Nitrate: 2-5ppm
Phosphate: 0.02ppm

I currently dose 15ml NOPO-X daily to keep nitrates in check as I have a heavy bio load. I dose 2-part for Alk/Cal, run GAC and GFO in reactors. Nothing else is added to the tank.


I no longer have a refuge in after the chaeto didn’t last. I don’t know if it is coincidence or completely an aside but the last chaeto to melt was when the slime appeared.

Here are a couple photos of the sump and filters which are constantly plugged up with this stuff. I’m stuck every couple days cleaning out my reactor pumps which suck up this stuff... please help!
