discovered that ours is getting contaminated with it recently, tho' i've put in some taddies in there a couple of weeks ago. will be alright if i were to still try to remove the mass of stringy algae whilst they're still developing? also noticed that the water level keeps dropping - about 2" every few days. the pond is actually made out of a recycled plastic storage box that's sunken in the ground, and it's at the top of the plot where it's on a hill, so it can get a bit windy there. i'm planning to have my newly-planted perennials to cast some shade over it so that will reduce the light levels a bit ... or do you think i should put something there now to stop the algae to multiplying so quickly ::) :(
