's only work if they are setup and maintained properly. Generally they are not that simple. While deep sand beds can aid in denitrification dsb
do not process phosphates and actually aragonite sand will bind excess phosphate. This means that overtime your sandbed will become loaded with phosphates unless phosphate levels are kept in constant check through water changes, macro algaes and/or gfo
. A heavy bioload may require all three to control phosphates. Water changes alone will not remove decaying material trapped in the sand bed.
This is further compounded by the fact that stirring or disturbing a dsb
can have major consequences if not done properly.
Not something i would recommend for new reefers. A lot of variables.
