I’m at that fun diatom stage of my tank presumably feeding off of the sand or dry rock silicates. Do these brown diatoms also consume phosphates? I ask because, well, I can’t seem to show any on my test kits with nitrates sitting at 7.5. My corals look fine but my chaeto is also melting making me think that I’m just low on phosphates but wanted to see if the diatoms would be consuming them fast enough to produce a zero reading on phosphates vs actually not having phosphates.
