green slimy pond


since the warmer weather has set in, my koi pond has been getting progressively worse until last week I could label it as an algae bloom and was forced to do something about it. The fish didn't seem too disturbed. in fact they seem to have gotten friendlier since the water is so murky they can easy hide from you so they are swimming closer to the surface.
however the pond is looking pretty bad and starting to stink. I had to purchase a second biofilter unit (the small one on the right) hopefully this should clear up the pond.
