Light combination

[hsloo]

Hi,

For a 4*2.5*2.5 ft tank, do you think 2*250W 10K and 1*150W 6500K in the center is a good combination? There is a plan to put SPS after the tank is mature, and of course chiller will be in placed too.

It's interesting know why you choose this combi.

10000K are white and will be influenced by other bulbs, so adding a 6500K will only make the tank yellowish but not as yellow as 6500K alone. For a more interesting colour, you might want to consider using a blue bulb instead of 6500K in the middle. This will give your tank a bluer look which is more pleasing to the eye.

Hi,

If i were to add 2*ATI T5 Actinic Blue - 54 watts, then it should able to reduce the yellowish colour further, right? The main purpose i want to use the 6500K is to have a better growth of he SPS, if i'm right.

well 10k is enough for growth for sps...

if i were you I will choose to go for the centre 150w mh to be 20k

plus since u mention about better growth in 6500, yes true but dont forget your centre one is 150w only.. will be of no use unless your sps is at the top

The antinic blue will cancel out the yellow making it whiter. Provided in suficcient amount.

Why not use 2x6500K and 1x20000k?? (Cheaper also) the 20000k will make the color white instead of yellow. using 2x10000k is white but add one 6500 will make it a bit yellow.

Be careful of light banding. It'll spoil the look of the tank.

Having a blue MH between 2 yellow ones is a bad idea! Unless you buy three seperate pendants and raise the middle one with the 20k much higher so the reflector can spread wide enough to cover the whole tank.

I suggest you get 2 x 10k MH and supplement with enough blue/actinic T5s along the length of the tank for coverage.
