we have a fairly large pond 8ft/6ft  although we have two pond pumps going 24/7 with filter light to clean the water although we have renewed the bulbs the water is not perfectly clear as I would have expected   

ive been told you can buy a product called em mudballs from harrod horticultural but im a bit unsure about using this product so has  anyone used em mudballs or any alternative to improve pond water as i said im unsure about any product because i don't whant to harm the fish

and advise on this matter would be much appreciated thank you

More plants to get the eco balance right might be better

When you say "clean the water" do you mean it is green due to algal growth? I'm guessing you do.

My son built a 10 foot square pond for koi carp then moved leaving me the job of looking after it. We have a pretty hefty pump and filter running day and night and a UV light which should have been switched on earlier in the year.... add blanket-weed and it has been / is fun. (?)

Blanket weed is now under control through use of chemicals and frequent cleaning of the entire filter system (hate that job) but an alternative for removal of green water is to try barley straw as well as keeping the UV light running (costly).

A bale of 'barley straw' in the water apparently produces "something or other" that consumes the green algae. Personally not tried it but may soon need to research it and have ago.. although there has been a big improvement in water clarity it would be nice to see more of the flipping great fish that surface like Moby Dick at feeding time.
