Firstly thank you all for your comments! Okay, so the algae is gone as best I could manage. Had to lift some plants. Was quite interesting how it had wrapped up the pots below the water too.
oxygenating plants in the pond are
Eleocharis acicularis (which the water snails seem to quite like)
another which looks similar to the one above but isn't the same
another one which looks like an oxalis (in the pic at the top of the post)
other plants in the pond
forget me not
typha minima (was hoping this might attract damsel/dragonflies)
also if there's interest, the pond dimensions are 60cm dia. 30cm depth. I think another problem with little ponds, aside from them being quite small to have a full ecosystem, is that it's raised above ground level, which makes it even more at risk from the sun with heating the sides too. Especially with having a black bucket as I do.. Thinking of painting it white to try and lessen the heating as well as sorting out more shade.
Mosquito larvae will stick around for now then. Should be good for bats at least.
