POISON DART FROGS
Lighting
A lighting of a tanks also serves the simulation of the day / night rhythm, in particular in rooms without daylight. In my opinion the need is more directed to the claims of the cultivated plants, than to those of the frogs. To produce the vitamin D3 of vital importance, frogs also need suitable ultraviolet rays. However, can be renounced by the addition of vitamins with the feed on it completely, without damages or developing problems appear. Also a UV radiotherapy of the tadpoles is very debatable and is not carried out by myself. UV measurements have confirmed which the values given by the manufacturer do not reach at all or only in very small quantities to the animals. Everybody can save the expensive UV fluorescent lamps and instal, instead, easy halogen emitters whose protective disc is to be removed then. Here the ultraviolet rays are higher around multiple and then reach also the animals. Indeed, should become here only in short intervals robbed. (Information, however, without guarantee)
So that nutrients can be formed, a process which one calls photosynthesis must run off in the sheets of the plant. If the light intensity is too low and/or the spectrum of the lighting is wrong (below the middle colour temperature of approx. 5,300 Kelvin), the nutrients educated by the photosynthesis are not enough and the plant does not become any more full, they starved. A daylight lamp delivers, e.g., for the photosynthesis of the plants to necessary red and blue points for the education of carbohydrate, the basic food of all living organisms, are responsible. As a by-product oxygen is delivered. If one lights up his plants less than 10 hours on the day, they remain rather medium-sized, with more than 10 hours you can also reach a higher growth. However, more than 12 hours - cycle your plants take amiss you, because also they need her night's rest (dark phase). The usually used Glow or energy savings lights have a colour temperature of approx. 2,800 Kelvin, they are not suitable for a sufficient care of the plants. The same applies to budgetary-customary neon / fluorescent lamps and halogen lamps, her colour temperature is higher with approx. 3,200 Kelvin only slightly. The metabolism with plants is subjected to a cycle which needs a quiescence of from at least 3 to 6 hours between the lighting phase. In this time certain materials from the sheets are removed, however, supplied other.
Light bulbs are exceptionally uneconomical (high power consumption)., the delivered colour temperature also does not correspond to the needs of the plants. Mercury-high-pressure lamps (HQL) are out, because of the high yellow portion in the colour rendering. Moreover, they are also very uneconomical (high power consumption). Halogen-metal steam lamps have the same technology like the HQL's (high power consumption), however, have a similar chromatic circle like the sunlight and are useful, indeed, the acquisition and also the company is very costly. Fluorescent lamps exceptionally feel well in her luminosity and correspond in this area absolutely to the daylight lamp, indeed, they generate a lower colour temperature - fluorescent lamps are available in the light colours daylight-white (> in 5000 K), neutral-white (in 4000 K) and warm-white (< in 3300 K). The light colour of fluorescent lamps changes in the course of the time in the yellowish. Thereby originate in colour difference to old and new fluorescent lamps.
Tip:
The lighting should be installed in general beyond the terrarium. For an easy lighting is advisable to lie down a fluorescent lamp on the tank. By the use of UV lamps is to be paid attention to the fact that the ultraviolet rays are filtered by normal window glasses. Therefore, the cover disc either of Perspex or special UV-permeable glass must be used, or the lamp will be laid on the gauze of the ventilation opening. However, with the latter the achievement is clearly diminished. A too strong lighting can lead to higher temperatures in the tank. This should be adapted to the respective kind. Often less is more good.
