I'm planning on building a new system soon which will inhabit several nps corals and filter feeders. I cant decide on a deep or shallow sand bed. Ive read that a dsb can be a food source but ive also read they can become phosphate saturated over time and can become a problem. do i go with a shallow bed that i vacuum and maintain while manually feeding the filter feeders? or do i go with a dsb and regularly restock fauna. i prefer the latter as it sounds like less work and more natural but i dont want a saturated dsb that needs replacement down the road.
