If it had been feasible to collect daylight, and by some technique store and control it in the exact same manner as we can with electricity, we would have the ideal lighting. Regrettably, at the time of writing anyway, it’s not feasible, and we need to resort to means within our scope.
Whenever you choose a position for your aquarium, attempt to place it to ensure that it’ll get its fair share of daylight. The light should be diffused, and also the tank should obtain a minimum of two hours of direct sun every day, which is really a minimum if plants are to function correctly. If too strong a light penetrates the tank, it’ll trigger the excessive growth of algae, which takes the form of cloudy green water, mossy growth on the plants, or a green film on the glass, and occasionally a combination of all 3. Should you need to use extremely raw water the actual surface will turn out to be coated.
You are able to control this by shading the aquarium with newspaper, green tinted Cellophane, or by painting the glass sides with a green paint. The shading or cutting down of the light should be treated with caution.
It’s much better to have too a lot light than not sufficient. Algae aren’t harmful to fish, but just the opposite. Plants can’t give off oxygen unless they’re stimulated by light. But should you can arrange I your tank in a position where it’ll get just the correct quantity of light, so a lot the much better. There’s no formula for this. You obtain the very best outcomes by trial and error, and all that’s essentially needed is really a small patience.
