They don't seem to have anything like the effect dino's have on phosphate consumption however, so nutrient corrections are usually very minor.
They can also be toxic, so I'd recommend the same activated carbon treatment while they're blooming.
To anyone interested – check out @reeferfoxx's posts on the topic as well......many of which you'll see under the #chrysophyte tag if you click it.
Your pic kinda looks #chrysophyte-like to me. (click that tag) @reeferfoxx has lots of posts on the topic that will help too!!
If you can get a $10 toy microscope (see: Selecting a microscope) you could look at a sample and know almost for sure what it is. Highly recommended on general principle.....feels like a no-brainer at $10. Troubleshooting with a blindfold on is always harder!
TO me your pic looks like a very new tank that may or may not have GFO and carbon being used on it and which has the lights on but a CUC and coral load that's near-zero or zero.
If you don't have corals, I'd probably have the lights off. If you do, then you need a lot more snails.
Tank is too small for an urchin.
Also too small for that blenny.
Turbo's are probably too big in the long run, but good to get things under control. (Don't let them starve later on by preventing GOOD ALGAE from growing in your tank – they need it.)
Leave the hermits off the order.
