I personally would cover the tank with orphek light bars or nicer BB – and I mean cover the entire tank! The reason being is that I would want to cover as much of the tank's surface area as possible. I am a fan of orphek v4 but the cost to cover that tank I would probably elect for the bars – however after owning AI, ecotechs, kessils, orpheks and various BB I think nearly the entire surface area should directly have light over it. I would get the 36” bars (to run front to back - the width of the tank) and put them about every 1ft give or take with the ability to add more and put them closer together if needed. 11 bars x $120 each for 1,320 to start with. Then can check PAR and add more and scoot them closer easily if using something like 80/20 mounts. I might end up wanting to have them every 6 inches. You can even have custom layouts done if you want it. Seems like a good way to get nice coverage. Can also pick different optics if you wanted to hang them higher or needed more penetration. 45w for this size of bar each.
