Hello.

I'm already preparing for next spring, so I have a question.

I have a small pond for the propagation, after the eggs hatch I transfer the larvae in another small pond with the light.

But I have a small problem, there is filamentous algae on some eggs and the eggs don't hatch.

So I thought to put a floating board over the eggs to cut the light and prevent the algae.

Do you thing it can work and if the shade will not harm the eggs.

Thank you.
A+

The shade should not reduce the hatching success because the eggs will receive some incident and reflected light. I am not sure the covering board will reduce the light to where the FA will not grow. Run a test with two egg ribbons one with covering, one without covering.
