CORALLINE.....

[noelskii]

once you start growing coralline in your tank...is it gonna bloom jes like as if it were a diatom bloom? meaning like itll cover the glass and rocks by the end of the day?

No, it takes a little longer than that, but will spread to your glass and phs and anything it can stick to, except the sand.

...and we're talking on the order of months, not days. The rate of growth seems pretty linear, as opposed to diatoms.
