Gravel Vacuuming deep sand beds.
Hello fellow fish geeks,
I have been keeping a deep sand bed on all 4 of my reef tanks for a long time, and have found by my experience that the most efficient way of running a bed like that is to do several things. My experience leads me to belive that most water changes should be done without vacuuming the sand bed, but that about once every 4 months, a random third or so of the gravel gets vacuumed. That way I export nutrients and at the same time I keep the sand bed healthy. However, I am more than happy to learn from other peoples ideas, experiences and decisions. So, could you please take this poll and provide the community with any insight that you have.
