Do either of you have a deep sand bed? I was reading a very long discussion on RC about them and why they often cause crashes or coral loss eventually. It gets pretty hard to keep them clean as a reef matures and fills in (hard to even see them anymore in some cases as coral grows). I don't completely understand the concept but I guess to do it right, you have to vaccum the top layer regularly so that waste does not get trapped in the deep sand bed. People likened it to a septic tank that just can't hold anymore waste and has no where to "drain". Don't know if that's applicable here but just a thought? Regardless, this is terrible ![]() |
