| My thoughts when first seeing the water (and Ian's when he saw the pictures) were that the fish are dead. Have you ever seen a fish that has died and sat in a bag of water (or bowl) for some time? The water turns this red-brown colour and a fine sediment (body fluids?) covers the bottom surface once decomposition begins to take place . The only thing that wasn't present was the smell - that awful smell of dead decay, not even a whiff in the air... but then it's cold, not sure that makes a difference..? Today the air temp was +13C here. I truly hope my first impression is not the case and the koi are alive and well.

Because of the cover which is a tarp which lets little light through as well as the snow the alge at the side of the pond died . I recommend lots of water changes . There is a shelf in pond so any dead fish would float up and be underneath that huge slab of rock . I would try and pump some water under just to make sure . The fish were under fed and filtration was not good enough so I declined to sell her more fish hopefully when water clears it is not dead fish .
She brought a sample of water instead of the dead algae I asked her to bring . At current water temperatures there would be little or no smell from a dead fish .

Ps on May 25th water garden society is a t my place would you and Ian give talk on water quality ? |
