We have a fairly new pond - filled with well water which has been filtered through the ground, so basically rain water.
Some of the new oxygenating plants were eaten by a pair of ducks, the other oxygenators have died. The marginal and lily plants are alive but don't look too healthy.
The water in the pond is clear - there are plenty of water boatmen and there were mosquitoes which thankfully have now flown away.
Why are the plants struggling to survive? We are having the water tested tomorrow at a shop that deals with ponds and plants. Could the water be too acidic?
