I have a 50gal AIO with high phosphate (0.4 — yes 0.4 not 0.04) and according to my ICP test, Silicon (not silicate) is 402.00 µg/l. (Range is 0-200). Nitrate is less than 2ppm and I dose every other day.

I had some blue clove polyps growing like a weed so I redid my scape and got a new piece of rock from LFS (Carribsea “Live” dry rock). This new rock (and only this rock) is covered in what I assume is diatoms. Brown dusty material, and with the new rock and elevated phosphate, I assume it will go away soon. But, I have lost about 4-7 snails the past 2 weeks or so, which makes me think Dinos possibly? It looks like rust and gives off little bubbles when my flow is off.

Coral is mixed reef and thriving. Only 2 clowns as I lost everything in January and had to go fallow for a bit.

Any thoughts or help? Let it run its course or should I use PhosGuard or something similar?

I’d say diatoms… if it were Dino’s it’s not picky about where it goes and smothers everything lol.. that rock is most likely leaching and causing a harmless diatom bloom that will fade away in time.

That’s what I assumed, but wanted to get a second opinion because my snails dying off have me wondering what’s going on
