Hey guys
have anyone of you tried mixing light spectrum in planted aquariums? if anyone of you have tried it, what spectrum did you use?
what spectrum will look good with 8000k?
thanks

Hi Neil,
you may want to speak with essabee on this, he has mixed a few spectrums and found great results.
warm regards

| I've seen many tanks that use 6500K + 8000K combination. I used to have a fixture with 5200K MH x 2, 6500K T5HO x 3 and a 8000K T5HO x 1. 6500K should suffice, 8000K just provides more light penetration. |

actually i observed that with 8000k, plants look more reddish. so want to experiment with lighting.
about 6500k + 8000k, if i had to use 6 t5s, would 3 of 6500k and 3 of 8000k do? or i need to reduce the number of 8000k tubes? |

| Remember one thing. There is no hard and fast relation between the Spectrum of the light coming out of the bulb with the kelvin rating of the bulb always. |

I believe the plants look redder due to the higher amount light that penetrates when using 8000K, the plants should also exhibit the same red when given high intensity lighting at 6500K.
Either 3x 8000K or 2x 8000K should be fine. If your tank is 2' deep, get 3x 8000K. You can mount 2 towards the front of your tank and the third toward the back. This will allow more light to reach the shorter foreground plants.
Sorry, I don't have a picture of my tank with that fixture, but the light had a golden-yellow colour with the MHs were on. With just the T5s, it was more bluish-white. I couldn't make out too much of a difference between the colours of the T5s but that's probably due to the ratio being skewed towards the 6500Ks.
It sounds like you're going for a high light setup, just a word of warning: Be prepared to spend a lot of time fine-tuning the setup and also maintaining it. The high tech, high light tanks aren't very forgiving |

| Using 8000 K alone will increase the blue end of the spectrum disproportionately. Excessive blue has a tendency of making the water look misty. |

just 8000k works just fine for my plants. my 7gl with Sakura and Fire Reds has 2x8000k tubes running on it. super bright but my riccia just LOVES it.
this is the one with 1x8000k tube and 1x15000k.
