Actually, I'm finished up with the live rock..I have a cave on the left and a toadstool-like column on the right, with an open space in the middle...the next step is waiting for it to finish cycling, then getting through my first
algae outbreaks....I'm going to add some cleaner shrimp and
astrea snails as soon as the cycling is completed.
The refugiums are an extra space where the amphipods, copepods, and other small animals can grow uninhibited. Additionally, there usually is macroalgae as an extra export for biological substances. I have a sand bed in mine, in addition to Caulerpa macroalgae.
