Hi in addition to all other problemd going on with fish dying due to parasites i also have a lot of white foam floating on pond. Ive tried treatments with approved chemicals which disperses it only for it to reapear shortly afterwords. I have pond filter pump and another pump in my 6000 litre pond. Im told too much protein may be the cause. Anyone any ideas
As nathangoudie, points out white foam, particularly where there is agitated water (Waterfall / filter return) is caused by too much protein, I would say too much food. Also from this end of the telescope you seem to be "adding chemicals" for the sake of wasting money, you really should find out what is wrong and with what fish, and put the affected fish in a quarantine tank, that way you save money and don't give "chemicals" to fish that do not need it.
