NT Labs Eradik Anti-Parasite Fungus Pond Water Fish Treatment 250ml for 4,550 litres

Nothing

I won't know until the weather warms up, how good or bad this is.

Appears to have worked well

Took 3 goes instead of the 2 recommended, but cured the fish. Follow the instructions, it's all about the pharmacology.

This definitely cleared up the problem with my fish, and I will continue to use it from time to time as a preventative measure.However, the bottle is a bit tricky to use - you can’t tell if the right dose has moved into the dispensing section, and shaking / squeezing the bottle doesn’t seem to make any difference. So I wasn’t sure if enough was being used for each dose.

It works!

to save the fish in the pond

Still had fish die dont know weather they had parasites or not. So i cant really judge this
