Will the 20" sunpod hqi 150w be enough light for my 30 gallon rimless jbj biocube? i have lps and sps coral there is also a 120w full spectrum led i was looking at.

I currently have a jbj unibody 54watt led and my corals are starting to bleach.

Could be too much light. Are they dimmable at all?

 

[Flowin]

Ya there dimmable but i looked it up and it says that i should have more than 54 watts.

If they are bleaching, that means they are getting a lil too much light, try dialing it back a lil bit. Also its hard to judge leds by wattage in comparison to other forms of lighting. Their efficency is higher then others therefore it throws some old calculations and guidelines out

 

[Flowin]

Oh alright the 54 watts are fine just dim it down a little?

 

[Dav3]

Yes. Try 50%. If they continue to bleach after a day or two go down to 25%.

Also, you may want to turn the whites down lower than blues.

And after having them dimmed for a while and corals start to turn brown you can turn the lights back up. But just a few degrees a week.

From what i understand, leds usually have hogher penetration power than other light sources. So you dont need as much power to keep your coral happy

Alright thanks i was pretty confused haha i will post some pictures after work of the corals and light.

 

[Flowin]

My corals look like there dieing out and bleaching and my anenome is grabbing for light.

 

[Dav3]

Takes time for lighting changes to take affect. Weeks or months sometimes. They will decline faster than they recover. Move the corals that are the most bleached to the sandbed while taking each coral's flow requirements into consideration. Anemone will move if it needs more light or move whatever it is attached to higher.

And I wouldn't worry about the toadstool(first pic) as they are very hardy.

Alright thanks ill keep the jbj unibody and just dim it for awhile
