[APD] Algea bubbles
When I have the CO2 and nutrient-levels on target I notice extreme
bubbling from algae attached to my driftwood near the light down to a
very special depth where the bubbling radically declines in intensity.
But now the bubbling has stopped and the algae amount has
declined and/or turned whitish. Some bubbling still occour after
the the threshold depth, see movies.
What's this about? Why the threshold, and why have it all of
a sudden stopped bubbling and turned somewhat white?
Have I "overdriven" the algea above the threshold?
