The seaweed surface provides a suitable substratum for the settlement of microorgansims and also secretes various organic substances that function as nutrients for multiplication of bacteria and the formation of microbial biofilms (Steinberg et al., 2002; Staufenberger et al., 2008; Singh, 2013). Microbial communities living on the seaweed surface are highly complex, dynamic and consist of a consortium of microorganisms including bacteria, fungi, diatoms, protozoa, spores and larvae of marine invertebrates
This is also the reason new ASW is a lousy substitute for real seawater. It takes a long time for these things to form in a home tank, if they ever form using ASW. In any case, they won't be present right away but may begin to accumulate if we allow algae to grow in our systems.
