To paraphrase: POM/SOM - particulate organic material/suspended organic material (detritus, reef snow, marine snow) composed by and large of the remains, secretions and excretions of living organisms uneaten food, and other debris. detritus tends to settle out of the water column, while suspended organic material is light enough, as it is nearly neutrally buoyant to remain afloat in the water column more easily (can be used by different organisms). Detritus can be algal composed mainly of dead filamentous algae and phytoplankton, and secondarily of fleshy macroalgae, coralline algae, zooxanthellae, cyanobacteria, phytoplankton and seagrasses. Non-algal detritus is mostly congealed coral mucus and fecal matter (varies by location on the reef). I've done a bit of reading previously, but just want to make sure. What I found interesting was the thought that we could make water TOO clean. I guess the thinking would be to keep nutrients around long enough to be beneficial/consumed but not long enough to become a problem. Quote:

Haven't decided on a method for filtration yet, but have a few ideas going around in my head. Thought is might be a good to get some input to make sure I understand the more complex parts. |
