Floating plants

[Byron]

The default settings for dawn/dusk are heavily blue, but easily adjustable. This fluval can do weird things like lightening storms. Designed for owners, not fish

Those flashes of light (I assume that is the lightening storm effect) are highly stressful on all the fish. Within the confines of an aquarium it is way more dangerous than any natural storm. The poor fish have no escape like they do in their habitats.

I saw them on a Fluval YouTube video & was horrified. They’d scare me too. Imagine peacefully sitting near the tank & it starts flashing.

The OP's problem, as @Byron said, is that *his* floating plants are dying.
