I am moving tanks... I am going bare bottom on the main tank.. and will have a deep bed sand filter in a separate refugium.

My current sand bed is 6 yrs undisturbed... and was moved from a prior tank with 4 yrs on it. Nitrates -0

1. Phosphates - builds up in Sand.. and can ???? release back into the system. Y/N...Maybe
2. Sand - Can the sand be regenerated to remove the phosphates... and then reseeded with live sand... or some of the old sand?
