    Not all diffusers are built the same -- BRS tested the AP700 diffuser and didn't have many positive things to say -- on the other hand, they loved the Radion diffuser.

    Seneye has PUR as well as PAR, how on the spot it is is unknown to be, but BRS was impressed

    Dana is looking at it as well. It’s an estimate based on corals with general xooox requirements.

    So in theory it won’t work for low light corals or highlight coral.

    So far as much as I can tell , the only way to get it to 100% would be to remove all the middle spectrum we use for visuals. It would look like a pink grow light at 100% pur , if I’m not mistaken. So IMO. Misleading.

    Possible, but aren't some of the peaks in chlorophyll in the reds and green as well? Does that fall into the middle spectrum or not so much?

    In the red yes, G Y O no.

    Red in most corals can be overdosed as well. In some other corals , V and some Blues can be overdosed.

    That's one of the main components behind the AB+ spectrum for Radion -- It's just a hair shy of 18k according to their spectrum slider (it's +1% on the whites, green, and red). And as we know, the AB+ is build on a bulb configuration of 8 blue+ and 2 ABS ati bulbs. THe first time I put in an ABS I was shocked how yellow and warm it was, it looks almost like a freshwater 7k planted light.

    But those who implement them swear by 'em. There's something in that warm spectrum the corals love.

    You are correct.
    This is not 100% accurate (Esp coral to Coral) but it’s a good guide line.

    IMO , that 660 has to include a bit broader range in the animals.

    I also run warm in my tanks. Cuz I like it.

    Also bear in mind you can mix any color temp a number of ways. By adding warmth or subtracting blue. Etc.

    Reads "25% or less reduction in PAR" so probably depends on what area of the tank you're measuring to a point. Also, the reduced light spillage is BS IMO. Regardless, I will be turning up intensity a bit more than I originally thought, but gradually..

    How have you liked the diffusers so far? Has it improved the shadowing?

    I haven’t added it yet but will have the reef up and rolling here in the next week. I will make sure to keep the thread posted of my observations.
