    Here's are several overviews on aquatic sediment. There is very weak understanding in the aquatic hobby, as well as focus, on sediments.

    Most if not all of the data presented (eg Kasslemann) is on the water column, yet most aquatic as well as most terrestrial plants can and do acquire nutrients from sediments as well as the leaves and stems.

    Overlooking this and measuring this other 1/2 of the fertilization seems unwise at best, and outright misleading at worst.

    In effort to address this, a set of articles should help aquarist gain the basic understanding about sediments and their role, function and cycling in natural and in aquarium systems.

    General:

    Redox and pH:

    Reddy's new text on Biogeochemistry of Wetlands (2008) is an excellent reference.

    This is specific research applied to wetlands with algae and plants, warmer temperatures etc.

    If you are interested in sediments, DIY soils, nutrients, I encourage you to look and learn further in this area, there is a great deal of good information and research available on sediments for aquatic macrophytes, periphyton and interactions with the water column.

    A good system that test the effects of denitrification(NH4/NO3 loss). I saw this chamber they used and the various equipment. I had wanted to add NH4+ and see which trophic levels got what fraction of each N through time(algae or submersed plants, then grazers % as periphyton algae etc).

    Also a good article demonstrating the effects plants have on anaerobic sediments and why heat cables, and providing large pore spaces/aerobic conditions for wetland plant roots is a poorly thought out idea.

    Hi Tom, Greg, All,

    Would it be possible to post the direct link for now to allow alternate access?
