@Y0uH0,
Algae could be an issue on direct sunlight, while I'm not too concerned because the duration is quite short (just several hours around noon) and the rest of the photoperiod can be compared to those of low to medium level lighting. Coloured lighting? perhaps night viewing light, artinic blue will do.
@fresh_newby,
That would be a great way to make sure while it would take some trouble to contact the designer/caretaker/consultor. My wild guess is a Netherland based company dealing in vivariums and open style indoor gardens. Lets see what will they say about using fewer bigger watt bulbs or multiple smaller watt bulbs (at the airport all I can observe are smaller bulbs that looks like 150W, 250W at most).
@CardBoardBoxProcessor,
Looking like which? The tank you referring to is on the balcony by the second floor and that explains the oddity of background. The stairs is back stairs that leads to the house deck. Behind that glass blocks is neigbour's house and we certainly need some privacy from preying eyes (which would be gazing at the tank because it blocks the view to inside). Looking like the airport fern garden is another thing... my economy is far from reaching that level, only some of the biggest corporate boss can afford that!
And for information, this project is on a different house (our old house which is under renovation).
@Hoppy,
LOL. I have to go on a diet then
