Question about dissolved nutrient level and detrivore.

In your recent article at reefkeeping.com you wrote:

"It is very important for the establishment of a deep sand bed, and the concurrent maintenance of a low dissolved nutrient level in our systems, that a varied fauna of these "micro-food" processors is established and maintained."

I am wondering what is the relationship between dissolved nutrient level and the animals? I know that it is best to mimic mother nature where nutrient levels are very low, but would like to know if there is conclusive evidence suggesting that high dissolved nutrient level would have adverse effects on the detrivores.

thanks.

Hi Win,

Most detritivores don't seem to be bothered by high dissolved nutrients.

The high dissolved nutrients, particularly phosphates are problems for other critters such as corals, where they interfere with calcification.

The animals that get "down and dirty" and grub around eating detritus don't seem to mind high nutrient levels, and may in fact cue on it as an indication of food.
