Ask away and I'm happy to answer....and excuse the bare tank...its a new tank build too


Thought some folks might be interested in some PAR readings from my build. Recap:
120G 4x2x2 Oceanic Tech tank
36" fixture
18 Cree CW
6 Cree NW
50 Cree RB
MW HLG 120-42B running the whites and 6 RBs
MW HLG 185-42B running 44 RBs

THERE ARE NO OPTICS ON THIS BUILD

Overall I am very happy and i think in the perfect range and in fact all my corals are responding very nicely...no burnout or bleaching! With optics there is no doubt the top of the tank would be too high. Thats not to say I couldn't add some 60 degree lenses on the very front row and the ends to focus a bit more on the sand and the sides of the tank.

The bottom row of measurements are on the sand next to the glass with the end readings in the corners so well away from the fixture. The ends of the center and top rows were taken just outside the fixture ends but the middle is under the fixture. I also am led to believe that the sensor reads the RB ~20% low due to the narrow spectrum but who knows.

Here they are
You have the same tank as I have and you are running a very similar led build!! I have 13 cw, 13 nw, 4 blue, and 39 rb running of 5 eln's all retrofitted into a 48 inch fixture, no optics, about 4 inches over the water. Works awsome.
