I was reading the info on placement of corals for long term success. It mentions the importance of water flow. Proper water flow will lead to detrius not being able to settle on the coral. My questions is.....on the flat spines, or whatever they are called that the bubbles come out between, there is what looks like brown algae growing on the tips. Does this mean that there is not enough water flow for the bubble coral? Should I scrub this off? Could this be why the bubble coral has not fully extended? |
