Not strictly true to be honest. Photosynthesis does use the blue end of
the spectrum as well as the yellow and red end. It's green that isn't
really needed, after all most plants reflect it :-)

Well, yeah, and in theory it's true. In practice, any other bulb besides
that one and the plants would grow better though.

The OP has really got marine lighting and would be best to dump both of
them for freshwater and plants.

Ayup.

Unless the other bulb was red/yellow in which case the actinic would be
needed to provide the blue :-)

I'm only replying because there is very little traffic in this group.
We both agree the OP would be far better off starting again with plant
friendly lighting.

Did the OP ever come back and say what they have done?

It's not a blue pant can easily utilize though. A 7500K bulb is what
you'd want here.

In addition to maintaining water quality, a key aspect in the establishment of a freshwater aquarium is a good lighting system. We humans, it is important for your pet fish, crabs and other underwater species have sufficient lighting.
