Speaking of light spread, the effective coverage for each fixture is approximately 2 feet in any direction. Trudi Wakelin, Director of Licensing, Marine Planning and Global Marine at the Marine Management Organisation said: Author’s note:With freshwater aquariums, the gallon capacity of a tank can be a relatively effective benchmark for the depth of an aquarium. In that part of the hobby, the most-used tanks have standard aquarium dimensions. For example, in 99% of the cases, a 55-gallon freshwater aquarium would have a depth of 21 inches (53.3 cm). The LED fixture itself looks futuristic, and in my opinion, it actually adds up to the external aesthetics of a reef tank. On the other hand, if your saltwater aquarium is between 20 and 24 inches deep then go with an IC LED version.

The specific set of wavelengths contained somewhere in the range of 400 to 700 nanometers that trigger photosynthesis in a particular photosynthetic organism – that’s PUR or Photosynthetic Usable (Utilizable) Radiation. These vary for different organisms. For corals, the PAR levels should be enough not to starve the photosynthetic algae. At the same time, they should not be too high to cause what’s known as coral bleaching (discoloration) and damage to the corals.And to not say that this is a single case, here’s another photo capture of a 225 gallon aquarium that’s heavy on SPS corals, having 3x VIPARSPECTRA LED lights over it: Speaking of intensity, the only way to control it along with light spread is by how far off the aquarium’s water surface you mount your PAR38 LED lighting. Of all the PAR, blue light chunk (435 to 495 nanometers) will have the strongest water penetration. WIth the XR15 PRO, you’ll be able to illuminate an effective coverage of almost 24″ for SPS corals, which is more than most point-lights on this premium list.

The A80 Series of LED lights from Kessil are an incredible powerhouse of a light in an inexpensive, silent-running a stylish form factor. Nowadays there’s more data and reports from people using it, which makes whatever findings I have about it – somewhat confirmable. I’ve found that for maximum efficiency and healthy coral growth, I would have to position the light high and dim the intensity.Anyway, it can either be mounted at the suggested 7 inches off the water surface or you can go higher, and ramp up the intensity a little to compensate for the PAR while having great coverage.

That’s more than 15 years on a regular photoperiod. However, the parts that would go out earlier are things such as fans and adapters.And here’s a 13-inch deep, saltwater fish tank that has 2 x AI Prime LED fixtures while housing multiple varieties of LPS corals and a couple of SPS ones towards the top: For me, it’s very important that the lighting fixture I end up with does not spoil the overall appearance of my marine aquarium. Just like the A80 Series from Kessil, each A360 light comes with 2 dials on the top face. One dial allows you to manually tune the color of the light and the other tunes the intensity (power) of the light.

Before deciding on how many Kelvins the LED lights for your new saltwater tank should employ, you first need to understand what Kelvins really are.Anyway, my final evaluation is that the hardware of the Kessil AP9X LED lighting is outstanding and the software does its job. Get this light if you want to grow stunning SPS corals with some LPS and clams towards the bottom of the reef tank. Advantages: The decision is a result of close collaboration between MMO and the UK Civil Aviation Authority (CAA) and follows public consultations which were carried out earlier this year. You can slowly increase the intensity by around 5% every week and a half and see how your corals react.
