The Need for UVA Lighting For Reptiles Reptiles can see much farther into the UVA spectrum than humans… more so than can be provided by "regular" light bulbs. This allows them to perceive patterns and colors beyond what we can see. Depriving them of a large portion of their visible world can cause serious health issues, as well as physiological and ...

Yes, LED's can support thriving reef and fish-only saltwater tanks. Just like with traditional lighting, there are a ton of factors; including the type and quality of the LED, the color spectrum, LED lenses, the total output, and the specific requirements of the livestock. If you're looking for reef quality lighting, it's going to be at the upper end of ...

Note: This will be true for most, if not all, lizards, but not necessarily for snakes and possibly turtles, as their eyes are different. The idea behind the red bulbs was that reptiles couldn't see the red spectrum of light. With this in mind, the idea was you could have the red light on all night, keeping them warm, but not keeping them awake. It's pretty ...

Reptiles, just like humans, rely on sunlight for vitamin D3 synthesis. Vitamin D3, among a host of other things, helps with calcium absorption in the body, promoting strong bones (and in the case of shell-bearing reptiles, a strong shell, which is vital for protection from harm, but also in a practical sense, it is an extension of the animal's vertebral ...

So... First, a quick biology lesson on cones and rods. Rods are photoreceptive cells that are very light responsive and are responsible for most night vision capability. However, very dim light results in colorless vision and rods don't capture color. Cones are photoreceptive cells that are bright light responsive and are responsible for most color vision ...

These lights/tubes produce UVA and UVB. The same type of tubes are used in sunbeds and marine tanks To produce UVA, mercury inside the tube reacts with the gas and electricity. This is why you should never shatter tubes because you can get mercury poisoning and they have to be disposed of properly. The mercury will slowly stop to react as expected - as a ...

Depending on what type of tank you have, whether it's a reef or fish only, you're going to want a certain temperature of light. Normally, for a fish only tank, you're looking at a light around 5,000-6,500 Kelvin. If you have a reef tank, you'll want to have a light up to 10,000 Kelvin, but be sure to monitor it, as you don't want to harm the coral. Too much ...

The answer to your question is yes and no. If you are using UVA light (black light) then this is safe for your fish; most of the light sources used on fish tanks do emit these wavelengths to some degree, but the black light sources are coated with a material that filters out the other wavelengths from red to blue light so it radiates only near ultraviolet ...

Shrimp are more active at lower lighting and during complete blackouts (nighttime). If you would leave your light on for the entire day, they will go into hiding and become stressed. They will start losing color and eventually die. Not only your shrimp will suffer but you will almost certainly get a lot of algae. A source: http://www.redcherryshrimp.net/...

Yes, "eggcrate" means the sturdy cartons eggs are transported and sold in. It also means the general shape of egg cartons and can be used for materials like foam in that shape: A third meaning for "eggcrate" is a regular grid correctly called "eggcrate joint", which doesn't seem to have a proper German translation. The best ...

When generated artificially, UV light is generated in very narrow bands. So it is quite possible that you only get what is advertised. The generation is based on how atoms work - at the level of electrons, orbitals, energy levels... Of course, some residues exist also, including visible light, but I guess those residues are not enough for your purposes. Can ...

Reptiles need to thermoregulate so you should always have a daytime basking light along with the tube UVB light for the cooler end. Mercury vapor bulbs or metal halide bulbs for basking are the strongest for UV output as well as heat for basking. Some metal halides have hot spots (essential areas with too high UV output), Zoo-Med products are the way to go ...

Ok, I will leave the filter- and space-questions to others (I am not too good at those when it comes to turtles), but pointers about the light and the sitting on the flowers: About the light: Turtles do absolutely require UVB-light for their organism to work properly. That means sunlight, or a dedicated basking-lamp. Any bigger pet-store should have them. ...

Are you turning the lights on and off by hand? If so, I'd strongly recommend a timer, they cost around $10 USD on Amazon, or your favorite pet store. I personally think that inconsistent light times are far more stressful than the grade of light you have. It may take a few days (1-3) for fish to adjust to any lighting schedule you set. However, maybe the ...

You are correct--your conure's current feathers will remain until his next molt. I'm a little concerned that he is on a diet almost entirely of pellets. Conures like and need variety in their diets. My green-cheek get LaFeber's Nutriberries for conures (which are also fun foraging food), Ecotrition Essentials cockatiel food, and he loves red leaf lettuce, ...

Easy way.. buy a dawn to dusk photo cell. Wire it to a relay. Normal switching for photo cell porch light. On at dark, off at dawn. Relay on at night cuts power to your lights. At dawn relay off send power to your lights. No timer to set.

I know something about this subject because I've tried to find a lightswitch (for my home office) that does the same thing. I have tried two different timer wall switches that say they turn on at dusk (you have to enter your approximate latitude). We end up resetting them every few months anyway because the clocks they apparently put into such things aren't ...

I have live rock, coral, snails, crab, starfish, many other fish and invertebrates, and the led works fine. It runs cooler too. It may take more lights to get the same amount of lighting as you get from a standard lighting system (depending on the type of led setup you go for) and it can get really expensive, but it looks great.

Not knowing what type of corals you have (soft vs. hard) this is what I've come up with: If you have a hybrid fixture (metal halides/t5 combo body fixture) you will want them about 6-7" inches from bottom of the bulb to top of the water (most of these that come with legs are 4-6" which is okay but not optimal). If they're two different fixtures (a better ...

From a more technical perspective: IR is a notion for a wide range of wavelenghts. IR vision can be in near-IR or thermal which is on the other end of the range. Near-IR vision still needs the objects to be illuminated by an IR light source, and common IR LEDs are in this range (800-1000nm). And photons in the thermal IR range carry much less energy, so it's ...

There are an infinite number of ways to setup a reef so I won't point to any specific products. I'm also making the assumption that by reef you mean a marine tank with rock, coral displays, inverts, fish, etc. Before I even begin, you need to realize that $1000-$2000 may not get you where you are expecting with a 220 gallon reef tank build. You may be ...

I don't think the lights you mention is made for fish tanks. This doesn't mean they can't be used but a better choice would be to try finding lighting made for fish tanks. Maybe ask for some advice from shops that are selling aquarium equipment to find some lighting made for fish tanks that fits the size of your tank. I know this doesn't answer your ...

Nothing can be compared to natural sunlight. I recently moved my fish from artificial lighting to my balcony - open to air, sunlight and without a lid. The difference was evident within two weeks. At first, my fish were scared of the open. Now, their colours are significantly more saturated. The fish have also become incredibly active (and hence hungry). ...

As with most things related to fish keeping, it will depend on the type of fish you have and what you want to do with it. Although I don't think light will have a big impact, but the temperature definitely can. An interesting article can be found here: http://www.aquaticcommunity.com/aquarium/seasons.php In the tropics there is not a big difference in terms ...

DIY hanging kind of cage A cage from egg-crate-grid is resting onto two bent pipes. The pipes are hooked onto the tank's edges. The pipes are secured with screws to not disconnect. The cage holds together with some zip ties, also the cage is fixed with some of them onto the pipes. (I did not get any egg-crate-grid in Germany; because of this I used some ...

The only somewhat decent translations I could find were kunststoff-gitter or grid trennung. It may be helpful to use the term eggcrate grille when searching.

If I translate it to German I get all sorts of boxes to hold eggs in storage... and I saw this turtle basking tower ... as do-it-yourself-video on youtube Additionally, notice that pretty much everything looks like coming from another purpose. There are some tubes, probably normally used for ventilation. And there are some things which look quite suitable ...

I got a ready-made setup of 7500K LED light with 6 blue LEDs. It's giving very good results, but the only thing is blue light favours algae growth. That's the only factor which was killing my tank's beauty. If we increase the CO2 in tank (go for pressurized), it will easily solve the algae problem of the tank. Addition of Flourish Excel will also boost the ...
