right i am converting a 2ft juwel into a nano and i am confused on the light side of things lol

currently the tank is setup with a single t8 unit and takes a 15w tube

tank is 70ltrs and is 15g uk/ 18.4g in us

so in this will give me either 1w per gallon or .8w per gallon

now the tube i have installed at the mo is a daylight tube and has a 10,000k colour temperature (think this is the correct one)

but is this enough for the tank ?

also what is this blue tube and how does this work or what does it do

not looked at corals as i am unsure about the lighting

would leds work better than a tube for the white or the blue as you can get the moon lights in strips

sorry if this seems a bit dim but it is confusing me as it is my first marine

i am not an expert by any means but if you are looking for a quick maybe right answer i'd say that if you are planning to keep coral you are going to have to upgrade the lighting... if you want LED's e-bay has some good deals on it... they usually recommend PC lights, T-5HO or MH for coral keeping..

btw blue is the color corals use at deeper levels in the tank because the other light doesn't reach that far with enough intensity...

so i dont need blue tube at all then as i am not looking to keep coral but was looking at anemones

Anemones need a mature tank, and often even more intense lighting than many corals. I would not advise keeping an anemone in a nano.

Hubby and I have a 2 ft. 20 gallon with 130W (2x 65W bulbs) PC lighting. It is sufficient for many corals, even some SPS. We could probably keep an anemone but don't want to due to their ability to roam around the tank and sting coral.

you could put twin or quad T5's in the hood and then IMO you could keep quite a wide range of corals including anemones.
