While it looks kinda similar to ostreopsis in the tank, it is very different under the scope. They are VERY small and completely motionless.
They are easily basted or siphoned away but return the next day. They don't stick to coral flesh, but do stick to everything else. I FEEL like they are beating on my coralline but may be mixing cause with effect.
My nutrients are generous and stable around .1/10 for PO4 and NO3. Salinity, temps and ICP numbers are all nominal minus a trace or two.
They might have first appeared a few months ago when nitrates were a little higher and I was gradually drawing them down with WC and carbon dosing (vinegar) which I then weaned off. Now these things are accelerating a bit. I have to baste every 2 days or I cannot look at my tanks. Both systems now have them.
I feed heavy with frozen and nori. My (120G) display has just a skimmer, socks and WC for export. My (300G) frag system has the same plus large refugium. Both systems have significant flow for SPS. These do grow only in the low flow areas of the tanks.
So a few questions:
1) Agree my ID?
2) Why are they so dang happy in my systems?
3) How can I manage these things down?
