Hi there.
Yesterday my Dad was given something called "terramaya" more commonly known here as "Gold dust" to clear up the pond water. He was assured that even overdosing would not affect the fish, and as the petstore was a thriving one we thought they knew what they were talking about. Bad choice maybe, whatever the case is i didnt double check here

. Today the fish (goldfish and koi) are gasping at the water surface and i cant say the water is any clearer either. This has never happened before. We have a filter in there however its too small but we are looking for a small pool pump. the pond is abt +- 1000L.
Any ideas?
tnx
