i have a salt water reef tank with 150 watt metal halide 20000k?

Question

and i was wondering ! can i use a normal metal halide bulb which is 6400 kelvin instead of 20000 kelvin ; in other words is too much kelvin capacity necessary for the growth of anemone and coral . my tank is 50 gallon height 55 cm length 1 meter and width 45cm do you think also that 1 metal halide x 150 watt is enough for my tank or should i combine it with another metal halide lamp or any other kind of light if yes please specify the kind of light and power.

Answer 1

I'll agree with the others on this. The number is referred to as the color temperature. Have you ever taken a photograph indoors with incandescent or fluorescent lighting? Under incandescent light, the photo looks orangish and under fluorescent it looks bluish-green. This is an effect of color temperature. Your anemones and corals need light that's a specific color wavelength, so you'll need something in a higher range than 6400K, otherwise the photosynthetic algae within their cells won't be able to photosynthesize and produce food, and your anemones and corals will die.

Answer 2

You should not use a 6400k bulb in a reef system. It is way too yellow and will do nothing but promote algae growth and really not do much for corals. If your metal halide is your only light then you need to keep it in the 14000-20000k range for your corals. They need blue from higher kelvin lights to grow and live. 6400k is more for planted freshwater aquariums. Your 150w metal halide is a little small if it is the only light source. It's not really going to spread out enough over the length of your tank. 2 150w metal halides of 14000-20000k would do well for your tank. If you don't want to spend the extra money a few 65w actinics would do well and you could lower your metal halide to 10000k but no lower.

Answer 3

An additional 150 MH is a good idea, especially if you are trying to keep an anenome in that deep of a tank. A 6.4K is not going to be good for you. Also, avoid cheap bulbs, they are more costly and problematic than one that is $20 more. I would recommend at least one actinic CF or T5 to not make the tank so white if the 150 is lacking in the blue area.

Keep in mind that the 20k is the top temp of the lighting, not the only color given off.

If that driftwood releases tannins in the water those lights will artwork nicely. be taught your fertilizer regiment aswell. i've got seen discus stored at seventy 8 no subject aswell. i might see in spite of if it incredibly is sensible to have one bulb 10000k.. 67ook is acceptable even though it incredibly is yellow green easy. mixture it with crisp 10000k easy and you get a astounding results of mixing easy. plant alternatives all seem astounding... and bear in strategies the guideline of cardinals... in case you want 30.....purchase 40 poor adult adult males like to die.. a good component is to ask the puppy keep to get them organized for you. cardinals that stay on the puppy keep a minimum of two weeks in the past you purchase them have a miles far far extra advantageous danger of surviving the 1st week or so on your tank. they do exactly no longer return and forth nicely. good success
