Phosphate: How low is too low?

[CHSUB]

The intention of my post was simply to raise the topic of coral health. The other posts seem to focus only on the dino issue, but even when dinos aren’t present, corals can still be lost when phosphate is really limited.

Yes. Thing is without dinoflagellate discussions there is not much left to disagree about…and I can only play so much pickleball! Haha….
