Why is my Amazon frogbit melting?

Accepted Answer

Check whether water is landing on the leaves. Strong surface flow, splashing, and condensation are common causes of leaf deterioration.

Does Amazon frogbit need substrate?

No. It floats at the surface and takes nutrients primarily from the water column.

Accepted Answer

It can grow quickly when light and nutrients are available, so regular thinning is often necessary.
