Vodka?????No meds.Algae outbreaks are a natural part of the tank finding the equilibrium between what we put in and the Microsystems in the rocks( I look at these beautiful sculpted skinny towers of flat rocks that hold a lot of corals but not enough for a necessary ecosystem with mass.) 90g tank needs 110pounds rock. A little vodka now and than. Chaeto. Chaeto.
Gha, Bryopsis is eliminated by scrubbing the rock with wire brush than turkey basting away the debris that gathers in rock crevices and becomes the soil for the algae to grow. Three days later do it again and the algae will go away with less returning each attack. Promise. No meds to kill the ecosystem Re maintainance: I turkey baste the rocks And especially any zoa colonies, and turn the power heads on high for an hour prob twice a week. Stuff clogs a mesh sock right up.
no algae 24 months in a 3yo tank
