Emergency Pond Help

Hi, I’ve posted in my pond build, but thought I’d create a different post too, so it doesn’t get lost in all the pics of the other

All of a sudden the pond seemed to collapse. All my small fish have turned up dead in the space of 2 days. I’ve added a few pics of one i took out this morning. It looks to me like a fungal infection, but ot seems to have happened so quick. Can anyone confirm it is?

I also have 6 wether loaches in there, and 2 Sterlets about 8 inches. I know these may struggle if I treat the pond for it, but taking them out doesn’t seem to be an option at the minute as I doubt I could ever catch them all.

Is my best option to treat, but maybe 50% of what’ it says on the bottle an see if I can get rid that way?

DON'T treat them for anything unless you know what the problem is.

The white stuff on the fish is excess mucous produced by the fish to try and protect them from something bad in the water.

The fact a number of fish died suddenly at the same time would suggest poisoning.

The best treatment for excess mucous and poisoning is big water changes to dilute whatever is causing the problem.
Make sure any new water is free of chlorine/ chloramine before it's added to the pond.

If you use a garden hose to fill the pond, flush water through the hose for 5 minutes before filling the pond. This will remove any softening agents that have leached out of the hose.

Thanks for the reply, I actually thought some kind of poisoning first of all, until I seen that snot type stuff on my Black Moore. It also seems to be on one of the Weather Loaches swimming round.

I done a 25% change yesterday, an a slightly bigger one today. you think daily is to much?

do a 75% water change
