COPEPODS, THE IMORTALS.
TWO DIFFERENT EGGS.
Copepods have evolved to have two types of egg.
Standard eggs and resting eggs.
Resting eggs can live for 3 months, frozen, dried at 25 degrees, pass through fish guts.
For 2 years I have tried to kill them all.
Electrocution, high level of chlorine, UVC lamps, hot water with double strength vinger.
I even had them before, being 15 Years.
Delivered by tap water supplier and only started 2.5 years ago.
Now I filter tap water with. 5 micron filter and a faucet filter before entering tanks.
Copper sulfate pentahydrate solution 👌
.2 ppm is about safe. So I hit the tanks with 40 ppm.No fish, and the plants let were dead anyway.
After cleaning filters, they then soak in bucket with copper sulfate pentahydrate solution.
I have a plant tank room no fish and Copepods eat plant ( I can't sell them).
Water supplier response is nothing to see water meet all Quality levels .
Will this work or any other ideas.
Now have do I remove or kill resting eggs 🥚
Thanks Jason (I have no hair now)
