Osobno nisam koristio Arcadiu, ali bi ova kombinacija mogla biti dobra:
Arcadia Original Tropic

This fluorescent tube is specifically conceived on the emphasis of red
and blue peak values of the natural daily light, which are necessary
for photosynthesis. The created spectrum works in such a way that
fluorescent features of the fish are particularly emphasized. It seems
as you still more brightly would radiate. The tube spreads an easy
breath of Purpur/Pink, whereby a particularly warm appearance is given
to the aquarium.
Arcadia Freshwater

This fluorescent tube was particularly developed, in order to combine a
singular, particularly created color temperature of 7500 Kelvin, which
experiences its peak values in the green part of the spectrum, with one
expressed high light performance. The tube offers also a outstanding
color reproduction and stresses the natural colours of fish and plants.
In the fresh water aquarium the combination of Arcadia original
Tropical and Freshwater is recommended. This combination accented not
only the red and blue tones with the correct peak values for
photosynthesis, but emphasizes also the green tones of plants and leads
to good visibility and excellent color reproduction.
