I just noticed that some of my Chaeto is turning a bit white. I assume it is dying.
My nitrate testing continues to show bright yellow, or near zero. Yet I do have some Caulerpa Prolifera growing in the same refugium.
From searching through other posts, I noticed some contain their Chaeto in an elevated eggcrate shelf. I might try that. It would then be closer to the surface where there is more light and water circulation.
