bloom

Some 14 days ago there was a heat wave (as in: a few days when the temperatures rose above 22 C) and so we had growth of luxurious proportions in our experimental flumes:



These filamentous algae are not the same as the smaller planctonic algae which cause the dreaded toxic algal blooms. They are just the chaps nobody wants to tread on when getting into a fresh water lake because they're dreadfully slimy. They are a food source and only take over if there are too many nutrients in the water - and too much sun :)

Visit 2SweetnSaxy for a good dose of Watery Wednesday.

Wow, greatly captured bim. And I do hate to step on when there's so much algae, I feel there are monsters grabbing my feet. LOL.
