After 55 years of reefing, I don’t test much; I observe. I am fascinated with the ebb of flow of our ecosystems. As I peer into their micro world, it amazes me as to the complexity of biofiltration. In recalling a verse from a Beatles song “With a little help from our friends”, I lift up the flame scallop and Caulerpa Paspoides:
Flame Scallops are quite sensitive to water quality. They are the first to let me know when things are off.
Caulerpa Paspoides is my bioindicator for inorganic nutrients and trace minerals. At the moment, the slight increasing of white along the ends of some fronds tells me that nitrogen is limited. This white is a precursor to the seaweed going sexual.
My interpretation of a Caribbean lagoon.
