hi folks,

on submerged, exposed patches of this rubber pond liner, ive noticed ochre-coloured patches of what looks a bit like some form of aquatic lichen.
not that id know!

can anyone tell me what causes this discolouration please?
is it simply some form of oxidisation? ive only noticed it near the bank in the shallows.
if it IS a life-form, a few ecology details would be interesting to learn.
and finally, is it any kind of threat to the liner or its inhabitants?

sorry the pics are poor!

thanks mucho in adv,

ben



theres a patch of it on left of this pic and also beside the left forelimb of the frog in the centre of the pic;




another patch;



there are much bigger patches of the stuff but i couldnt get a passable pic of them im afraid.

pond is prob a decade or so old.

thanks. that makes a lot of sense now. iron oxide prescence explaining the colouration etc.

the "patterning" of the bacterial deposits seem curious.
its not just anywhere is it?
as shown in the pix, they seem to mainly follow waterscape features and boundaries or prominent high contours such as kinks in the liner.
presumably where conds are most favourable somehow?

in doing so, they bring me something resembling bacterial art reminiscent of mapping!
