Lighting

[njw]

I have a 180l tank that takes 2 lighting tubes (36", 30W). My tank is planted, and i need to replace one of the tubes as its acting up.

the question is, what tube to get? Currently, i have 1 interpet beauty light (the one that needs replacing) and 1 Triplus tube.

is this the right balance for plants and fish? ...and, is 30W sufficient?

Also, i was thinking of moonlights. are there any disadvantages of moonlights? Are they harmful to fish and/or plants? anyone have any experience with these?

Arcadia Freshwater is probably best for your plants if you're going to replace

The other option Original Tropical, but the first one is best

Not sure about the daylighting, but as for the blue lights, the only change that I've noticed is that my fish seem a lot more active during the daytime since they now have some semblace of their more natural habitat.
