Chinese blackbox led settings

[Sexytang]

I have a 165W blackbox led and just can’t find the spot. It’s hanging around 20” above my 27” tall tank. There’s a few bubble tip anemone and mushroom, zoa, Kenya tree, toadstool corals I have the blues at 100 and whites around 20 I’ve tryed moving it down to like 10” and 50/5 but nems closed up. What’s a good height and setting for this tank plan on adding some sps soon

Mine are about 8" above the water line. I would put them around there and turn the power down, slowly ramp it up to where you want it over time

 

[Sexytang]

Can I see pictures of your tank and what b/w setting you have them on

 

[Gernader]

I have mine at 100% blues and 10% whites mounted about 12” on a 75g. I’m growing SPS, anemones, hammers, etc.

Mine are now Frankenstein versions of the black boxes, I've swapped out a bunch of the let's over the years.

 

[Sexytang]

How far down are the nems

 

[Sexytang]

Is 24” above waterline way to high

Sounds like it's "spot lighting" which it's common. Pulling the lenses may help and allowing you do drop the fixture some. This will allow more adjustment up or down in intensity.

This is my bb and brs tested it mines at 21” if I move it down corals get ticked so im gonna keep it at 21” if everyone things it’s ok. Would like to try growing a monti cap and birds nest soon

Mines at 12" above waterline on a 125 gallon tank that's 21" tall. I don't have a nem, but I can grow just about anything with them. I do have most of my lenses pulled.

14” above water
Use caution, many CBB push very hi par.
I have not been able to get past 60%

 

[Sexytang]

Would it not almost be the same with me at 100 blue at 22” and you at 60 at 14

 

[Uncle99]

Not necessarily.
Ton of things stand between PAR and PUR
Just start low and move up monthly.
I didn’t get much beyond 60% on the Visparspectra, before corals started to get unhappy,

Hi flipper, what intensities are you running your lights?

I have my vipar spectras at 68 blue and 18 white. My anemone was at the bottom of the tank and has since moved right to the top of tank. it was settled for like. 3 weeks and went through a period of moving for a week. Had to move some corals and got really annoyed with it. Now my clowns are showing interest it. So all is well.
last time I checked I was pushing like 350-425 par in that area. Mine are 9” above the water. I have 3 of them on my 60” 120.

also above my centre brace I have the light up to 100 blue but I don’t remember the white channel. I have glass braces in the centre of the tank

 

[Sexytang]

I just moved mine to 7” off water and 100 blue and 20-30 white. What’s signs I need to watch for

 

[Sexytang]

I pulled my lenses a few days ago how far above tank should I go with blues at 100

 

[Sexytang]

Atm I have it 6” been messing around with it had it 11 earlier nems seem happier at 6 but I don’t know if I gave them enough time to adjust at 11.

Man I use 6 of them on my 180 both channels at 100%, I grow sps on the bottom of my 180. they are hanging 14in above waterline. Problem im having is color of the actual tank is too white for my liking. Been running this for over 2 years now.
