250w; 10k vs 14k

[Ban]

Hi anyone care to help.

Planning to keep SPS. Therefore need to upgrade 2units x 250W MH from 2x150w(14K). But not sure whether to get 10k or 14k light. I hear 10k, SPS will grow faster than 14k. But a little yellowish on the light. Whileas 14k is produce more white light than 10k, which look better in eye sight. Then how about aglae grow?

Anyone, care to advise me whether to get 10k or 14k light? Tks.

10K is suitable for yellow, red, pink acros & 14kk is for blue, green, purple acros.

so if u wan to hv twin MH..i will go for 1 10kk & 1 14kk. so u can place the acros accoding to the lighting zone to thrive. just my 2cents. to balance off the yellowish color get more actinic t5. just my 2cents.

hi jleejk,

Tks for your advise. Btw, you using 2 units of mh & T5 blue light?

If yes, mind to share with me what time u on/off the 1st mh, 2nd mh & T5 blue?

If you are using actinic supplemtation, there is no need to use a 14K light. 10K would be better for you. Personally, for most bulbs, there is not that much difference in a 10K or 14K light in terms of blueness, unless you go up to 20K.

bro i dun agree wif u... i hv seen XM 10kk...more yellowish color, blv 14kk crisp white...i m personal using hamilton 14kk is crisp blue. so kenot say which is blue or yellow ..but comparing temperature kelvin but need to consider the brand too.

s ofar XM 10kk got the highest par according sanjay joshi...but to me damn yellow man....definitely need lots of actinic to eliminate the yellow color.

hehehe actually now i m using single 250W SE hamilton 14kk wif luminrac supplement wif single t8 6500k bulb. i on the 6500k 1hr b4 & off 1hr after my mh is off. i switch on my mh at 3pm & off at 11pm.

u can power ur MH 8-12hrs daily. depends on ur tank needs. so far mine is ok. i might wan to increase further. FYI using only t8 6500k the algae oledi grow like crazy...i cant imagine reefer using t5 or mh for 6500k. but i notice my poccilora edouyxi & verucosa red color has enhance after my t8 6500k supplement.
