    I run primes and love them. Seems two of them is the magic number when tank is 24" or more
    These lights offer nice shimmer and grows everything

    Awesome thx. May I ask how long your tank is? And how deep? How many primes do you have?

    Imo 2 26's on a five foot tank would not be enough due to shadowing, yes you would have one more puck but they are pretty close together on the 26's and at least with Primes you can place the single pucks apart plus you could always add another at a later date if required.
    A lot of people don't realise just how powerfull these little pucks are and totaly underestimate them.
    I've been a Prime user for around 4 years (since release) on various tanks and tend to keep the same sort of stock you are thinking of, i have never had a problem with the light output they give out.

    I have a WB 45.2 Platinum Frag with the dimensions of 24x24x12. I have two AI Prime HD and keep acans, trachophylia, torches, Yuma mushrooms and nfs gorgonian. The lights are great - don’t/can’t use full power. Get good growth. Very happy with Prime HDs

    I ran two ai primes on a 48 inch long lps and soft coral tank for years and had nothing but success. I would get the three for your tank. If you ever want more light you can add a fourth and get much better spread than two 26s would give you.

    So I’m either going w 3 primes knowing I may add a 4th down the road, or 2 of the 26’s knowing u may add a 3rd down the road. Decisions decisions. I wonder if AI has a PAR reading chart at different depths for each of their lights

    I use 4 AI HD Primes on mt 75 Gallon tank. I go have some SPS, but mostly LPS and softies. They will penetrate to the bottom and do good. Picture shows what is happening.

    May I ask how long the tank is? Also, it looks like you have another light above the primes. Or am I mistaken?

    that guy is using the basic bracket mount and then runs a par test at the end using the AB+ settings basically, so that gives you an idea



    and they do some par readings too

    The tank is 48 inches long. There is a fan for cooling, Ehiem Auto Feeder, and Television above the tank. Only lights are the AI HD Primes. Tank is 21 inches deep and 18 inches from to back. It is a Standard Aqueon Reef Ready 75 Gallon Tank.

    If your tank is no deeper than 18" you should be fine. I have a 24x24x24 but I am growing SPS with 2 T5s and a 26HD.
    I have no issues with light but when I had two first version AI Primes I did have issues with enough light. I moved those two lights to another tank that is 18" deep and I have no issues in that tank now. If you feel you need more light than the 3 AI Prime HD's I would look adding T5s it will soften the disco effect and give just enough light but not over power things. If you spring for dimmable ballast that even makes it better.

    I think you will be fine with the 3 AI Prime HDs if spaced properly, I have two AI Primes on a 30 gallon that is 18" deep.
    If you feel you need just a little more coverage add two or three T5s. I have done that an I now have a mixed reef with 1 26HD two t5s on a 24x24x24 cube.

    I’ve really enjoyed learning about most of the aspects of this wonderful hobby. From flow rates to turnover times to fish species and corals, its been fun. But lights are driving me absolutely mental. I’m ripping my hair out over this. Agghhh!!!!

    I run a Hydra 26 HD over a Reefer 170, and run it at roughly 55 watts of power (similar to an AI Prime HD); when I turned up the whites I bleached the @#$% out of a bunch of corals including ones at the bottom. If you ran Prime HD's at max (or close to it) I'd think that 2-3 lights would be fine for softies and LPS. 2 Hydra 26 HD's would also work.

    Look at it this way - it's like a multiple choice question with multiple correct answers! :-D

    That’s encouraging. How long is the tank?
