It must let more nutrients back into the tank, I have started not using one and my LPS/anems are really full/ not sure how itll be on the SPS. I like the idea of using one for a short while after stirring up the nutrients. My Brains/acans etc always recede while my SPS flourished using socks i just thought that its very low nutrient system that way if changed regularly. So hoping to see better results . Probably get some differences in the SPS though.
