    Hi guys

    I've recently put in a lot of effort time recreating my hood in order to make it more practical and friend - aluminium frame, light switch etc.

    I numbered the lights in the attached picture. There is 6 80watts and 2 34watts.
    Up until now I ran 3 20000k's and 3 10000K's. They are around 12 months old. I replaced 2 of them with a 12000K and an actinic- Both reeftek.

    The actinic is much more blue, actually purple and not as bright as the 20000K.
    The 20000K gives a more vibrant colour to the corals. Is it not suppose to be the other way around ? Or am I just seeing things ?:D I think I expected more from the actinic - it's not pure actinic btw.

    What do you guys recon is the best configuration. I really like the colours Tony and Preshan is achieving. It's much more blueish than what I have now.

    Cheers :1:

    Hi dude why didn't you do 2 x 80w then a 39w another 2 80W with 39watt next and lastly the 2 more 80watt - would give you more balanced colours in the tank?

    Your configuration is great if you're going for colouring up of corals. I you want the corals to grow I would leave the two 39W actinics then stagger one white one blue which will leave you with three blue lights and four white collectively.

    Thanks Tony & chikaboo! Chikaboo, the reason why I didn't placed them as you said is because I were afraid that it will light up the middle of the tank much more than the sides. I forgot to say that the 39w's it's one 14000k and one actinic (from what I can see - those lights are way due to replacement). To keep the balance I'm going to use the same lamps for both the 39w's. Creating one long lamp.

    Tony I'm trying to bring out the colours primarily and then enhancing the growth. I know it should be the other way around... :$

    So this is what I have: Black is lamps which are being replaced.

    1. 14000K ---- 2. actinic
    3. 10000k
    4. 20000k
    5. 12000K
    6. actinic
    7. 10000k
    8. 20000k​


    So this is what I have:

    1. 12000K ---- 2. 12000K
    3. Actinic
    4. 12000K
    5. Actinic
    6. 12000K
    7. Actinic
    8. 12000K

    I think with the 10000K's replaced with the 12000K's it will already give a more blue effect

    Some stuff I'm still uncertain about after hours of googling.

    1. what is the main differences and advantages between actinics and 20000k's?
    2. Is the Reeftek aquablue equivalent to a 20000K?
    3. Why is the 20000K brighter than the actinics ?
    4. Why is actinics more expensive than 20000K ?
    5. Which is better for corals ?

    I'm going to paint my back panel later today, it's having a beige wall background atm :D Do you guys think it will make a noticeable difference to the colour effect ?

    Sorry for all these questions about such a repetitive topic, there is just so much options to go with.

    I forgot to ask another thing, if the blue lights are mostly there for aesthetics do they also need to be replaced every 11 months ? I understand when the spectrum shift with white lights a red or yellow tint in the colour can be noticed but with the blues it look almost exactly the same as brand new lamps.

    Thanks :)

    Actinics are purely for aesthetics and wont really contribute to coral growth

    Personally, I think Actinics dont need to be changed so frequently.

    IMO Actinics are a waste of time in a T5 only lighting system. They work well in MH systems.

    If you want colour stay with the 20000K and mix it with 12000 & 10000K

    Too bad I bought an actinic :( I'll fill the rest of it up with 20000K's then, so will the 20000K contribute to coral growth, obviously not as much as a 10000K but more than an actinic ?

    Yes, IamAClown. Indeed. Remember the following: the higher the Kelvin rating, the blueer the white, and the more coloration pop, but the less the growth. The lower the Kelvin rating, the less the coloration pop, but the more the growth.

    Hi guys, I've found this article about PAR ratings for different lamps & kelvins.
    The difference in PAR ratings between a 10K & a 20K is smaller than I expected it to be. The actinics though, have a very low PAR reading.
