hi first time on forum need help.Had pond and koi for 2 years now and no prob untill now 2 of my fish have died within a week no visable signs of anything wrong all others seem ok any ideas

[bcfc]

you ent telling us much? water test?? scrape?? have u got air going in to pond??

[miles41]

bcfc is right....sudden deaths are always a mystery, but any clues with water parameters and general health of other koi may help?

Bit late replying had water tested all ok person at shop said it might be to clean i had replaced all my filters 2 weeks before and cleaned out my pump could this be the reason there is air going in to the pond and all other fish are ok thanks

Is there such a thing as 'too clean' water.....not sure about that I must say! Guess it goes to show how water tests are so important to check all the other parameters

u need to get a api test kit, and do it yourself, mark1fan sells these, click his banner. is there jumping? flashing? do u no someone with a scope?? maybe someone lives by u?? hope this helps.
