How many Kessil lights do I need?
How many Kessil A360X do I need over my tank? LPS and Soft Coral: A single A360X will cover a 24″ x 24″ area and provide PAR that is suitable for LPS and soft coral (75 -150 PAR). SPS Coral: You will want to use two A360X fixtures for every 24″ x 24″ area to provide PAR that is suitable for SPS corals (200 – 350 PAR).

How many Kessil A160WE do I need?

Kessil recommends one unit for an aquarium of roughly 50 x 25 x 30cm/20 x 10 x 12in, and two for aquariums of 90 x 45 x 30cm/36 x 18 x 12in. Power consumption for the A160WE is a maximum 40W.
What is Kessil logic?
Kessil Logic After many years of R&D, Kessil Logic can be found on all of Kessil’s LED lights. The A80 allows you to fine tune the overall color and intensity that the light puts out while keeping a spectrum that will be optimal for coral health and growth.
What does Kessil controller do?
With an aquarium controller like the apex or reef keeper you could use a 0 to 10 volt ports. And add more controllability to the castle lights such as ramping up the intensity.

How long do Kessil Lights last?
So for me, average is nominally 3.5 years so far with no failures yet.
What lights make corals pop?
To get your corals to pop with intense and strong fluorescence your light must have high intensity at the Violet Blue Cyan spectrum (400-490nm).
Can you run too much carbon reef tank?
Using too much carbon is strictly based on your current levels of nutrients. If your nutrients are high, and you throw a bunch of carbon at it which will bottom them out, you will most likely run into issues with any sensitive livestock.
Can you overdose carbon in reef tank?
Well-Known Member. To my knowledge you can’t overdose Activated Carbon. It stays there holding physically or chemically the impurities. On the other it’s best to use small quantities and replace often because better exposing leads to more particles trapped and thus more removed from the water.
Can APEX control Kessil lights?
The Kessil LED lights which will be directly controlled by the Apex must be connected over Wi-Fi to the same network as the Apex. Kessil A360X Tuna Blue and Tuna Sun lights equipped with a WiFi Dongle may be directly controlled by the Apex.

Do ZOAS prefer blue light?
Yes, zoas kept under largely blue lights will have better coloration. I went to see my friend’s home aquarium business and he runs all blue LEDs on his zoas to make the colors pop.
Are Kessil lights good?
Kessil lights are by far one of the easiest lighting systems to control and have success with. The simple control system and pre-set lighting spectrums let you adjust the spectrum of the light correctly for your tank while providing the proper light mixture of colors in the light for healthy coral growth and color.
Can you run a reef tank on just blue light?
Corals don’t need a white light to grow in your reef tank. Instead, they need blue light to grow healthily.
Do corals prefer blue or white light?
blue
Efficient photosynthesis requires not only adequate light intensity but also the correct spectrum of light. Terrestrial plants, like those found in our garden, favor colors in the yellow, orange, and red range while corals favor colors in the blue spectrum.
Can Too Much light hurt corals?
Corals exposed to too much light too quickly may expell zooxanthelae,bleach/loose color. The light stimulates unhelathy levels of zooxanthelae and photsynthesis which produces too much sugar and oxygen for the coral. It responds by expelling it’s symbiotic algae and or closing up.
Will adding more fish increase CO2?
More Fish: If your tank has the space, adding more oxygen-breathing creatures to your tank will increase the CO2 being released into the tank. Fish will usually produce enough CO2 for low-light plants and lots of fish will usually produce enough for medium-light plants to live but not thrive.
How often should you replace carbon in reef tank?
Carbon will become exhausted, for the most part, within the first week of use inside a reef tank. For this reason, we suggest replacing carbon every 1-2 weeks alongside your regular scheduled maintenance (water changes).
Does carbon dosing lower PH?
Carbon dosing can also lower the amount of oxygen in your tank. This will in turn lower your PH and your alkalinity. Both can lead serious and negative effects on all your livestock and corals in extreme cases if you are not closely watching your parameters and react to it quickly.
How long should you run carbon in a reef tank?
How do I connect my Kessil AP9X to WiFi?
Do zoas like high or low flow?
Ideally, your Zoanthids should live in a low to medium-high flow area. If placed in too high of a flow area, polyps will have a difficult time opening, which stunts its growth/development.
Do zoas like dirty water?
Ninja’s point, that zoas/palys can thrive in both clean or dirty tanks, provided that periodic nutrients are available agrees with my experience. Most zoas and palys seem to do well in high nutrient tanks with or without ancillary feedings.

Do corals prefer white or blue light?
Do corals like high flow?
Most small polyp stony corals thrive at high flow rates. Some SPS corals can grow well even when a high flow is directly aimed at them.
