So, I know the job of the bog filter is to act as both mechanical and biological filtration, but I wasn't sure about starting with pea gravel that is quite dirty to begin with and plants that aren't large enough to be doing much filtration yet since they are brand new. The moment water touches the gravel huge plumes of silt are coming off of it. Should I just ignore this, should I try to clean it more (rinsing it off doesn't seem to help all that much), or would it be helpful to run a mechanical filter on the pond bottom for the first week or two just to help clean this up? Were this my aquarium I'd just be stuffing my filter pump with cotton batting to remove it from the water column, but not sure that the aquarist's instinct is the right one here seeing as how there's gonna be plenty of gunk in the cycle in the future. Plumbing is set up at this point and water is in the main watergarden pond (300 gal above ground) but haven't turned the pump on yet.
