Strange algae covering rocks

[Wannareef122]

I encountered this first three weeks ago. During those three weeks I have lost the following livestock:

-majority of snails
-Coral branded shrimp
-sea urchin
-several reef hermit
-Hammer coral
-GSP

I have taken samples to my LFS and tested my water myself. Everything seems to be perfect.
My tank levels are as follows:
Phosphate: 0
Nitrate: 0
Ammonia: 0
PH: 8.4
Salinity: 1.026

I have also tested for heavy metals and tested negative.

Tank setup:
The tank has been set up for 9 months. It is a 55 gallon tank with a 20 gallon sump.

Anyone have any suggestions on what this could be? My other coral is not looking happy and worried that more stuff will die.

Steps I have taken:
Run phosguard
Dosed fluconazole
Manual Removal (it is back the next day after it is brushed off)
2 day black out period

A chrystophytes.

Stop running the phosphate remover. You have likely stripped too much out.

@saltyfilmfolks Does this type of algae normally kill livestock too?

Sadly , in a very small tank I’d say yes. Run purigen or carbon in high flow areas or a reactor.

@saltyfilmfolks Perfect, thank you so much for the help. I will remove the phosphate remover and run some carbon, then see what happens. I have been scrubbing the rocks daily but it seems to grow back almost instantly.

Is there anything that adds phosphate? Never really thought about having to add it, only to remove. I can increase the feeding of my fish but thats all I would know of.

Read that thread. It’s long I know.

What we see very often now with striving for zeros is the actual nitrifying bacteria die off and allow other organisms like dinos and Chrysto to take over.
That member is actually dosing no3 and Po4. After several week of it he dosed fluconazole and it died off. (In thought that was very interesting).

There is actually a giant dino thread here with similar information.

I had that white stuff and fluconazole wiped it out. I add phosphate with Seachem Flourish Phosphate. Seachem has a dosing calculator that is extremely accurate. Good luck.
