I have a small pond, approx 3m x 2m , 1 mtr depth. Its partly shaded with green shade cloth and I have a few plants and Lillies I took from some other ponds in the Area.

I have a few fish which I put in to test the water. I would like to intoduce some goldfish or maybe some ornamental carp when I'm sure the ponds ready to sustain them.

I made the mistake of intoducing some snails thinking they would keep the water clean and eat the detrius. These things grow to the size of a chicken egg and breed prolificly. They seem to be destroying the Lillies . I keep scooping them out , but its going to be a fulltime Job. Do I start again and empty the pond and clean out the snails or can I inroduce a type of fish that will eat the snail eggs and balance things out a bit. Or alternatlively alter the PH level and Kill them ?

you could try a few freshwater puffer fish they will eat them for you no problems most of the fish shops have them in if you go to the saturday market opposite bangkok hospital they have some good sized ones there every weekend
