I have recently installed a Boase Aquamax 6000 pump in my small garden
pond. Unfortunatly I think the pump is too big as my pond surface is
covered in foam. I am unable to see my fish or anything else through
this foam. Is this foam oxegenated water and is it caused by too much
flow down my waterfall? I am not able to restrict the pump flow by
inserting a valve in the hose line as this will cause the pump to cut
out. Is there anything else I can do other than replace the pump for a
smaller one.
Please help.
Chris Burton.

Any possibility the fish have spawned? A fishy smell about the pond?

If not, very likely the increase water flow (a good thing) has disturbed a
lot of organics, which cause foam. A water change (25%) and skimming off
the foam will help. Cleaning the water fall & bottom of debris will also
help. ~ jan
