NEW LIGHTING SET UP

[Spur2]

I was amazed how much light i have now with 2 400w SE luma max reflector compare to my 3 250w DE hamilton Reefstar Deluxe system. I don't have anymore shade spot in my tank. But i have a few question

To get the light work effectively, how far from water do you recommended? I have it hang approx 10-12" from the water.

Will i have enough flow with 1 tunze wavebox and 3000gph return pump split into two return?

what size tank?

The reefstars suck. I actually had Hamilton ragging me through some friends of mine for me commenting on that in "another" board, but the reality is that the reefstar is a terrible DE system. That being said, any DE system is much more "focused" as a light source vs the Lumenmax.

OOps, tank dimension 5x2x2. Trust me i am tire of Reefstar. Yesterday after finish installing my luma max reflector and fired up the new 20k radium bulbs, i try to remove the hamilton ballast. That darn thing shock me.

I have my 400 10 in above the water in a Lumanarc mini and get great spread on my 2x2

I should lower my lights a little. I should keep it around 8" from the water level.

hey do they cover a 3x3 area ?

I was actually told by Pacific Garden Supply that the Lumenarcs cover a 4x4 area, but that may be will a 1000W ballast.

im just wondering i wanna get rid of one of my 400w mh and stick with 2 of them on my 180

I didn't know that. Is that because the bulb has to be fitted close against the top of the reflector?

Yeah that can happen with MH gear. Last week I was screwing in a new bulb while the light was switched OFF and was holding the metal part and BANG!

That is the exact reason why I prefer SE bulbs now.

LAIIIs are rated for 4x4 (as are the lumenmax) with a 1000w ballast in horticultural use. They got those 5000k bulbs....yech.

Mine (the reflectors themselves are about 8" off the top. Seems to work well.

Same thing happened to me orion76. 400w is really strong huh

I think you might not keep any LPS in your tank now.
