murky pond after spawning
We have recently moved into a house with an established pond. It has been full of mating frogs (I would regularly count around 90) for the past 3 weeks, but now the frogs seem to have gone and the pond is covered in spawn.
The pond looks very murky and there seems to be algae. Some of the spawn has hatched but the tadpoles look immobile and dead. Is this normal? (I know a lot do die off). Could it be that there not enough oxygen because of the algae?
Is there anything I could do? I don't know what to plat. thee is a water plant in there, but I don't know what it is.
Sorry - new to all this!
Thanks for any advice you can give.
