BTA lighting.

[Ishy]

Can anyone tell me the ideal lighting spectrum and intensity for BTA's please, using LED's.

any reef spectrum is good. 10,000 kelvin to 20k.
prob the min Par would be 100 to crazy high 500 + id try to stay in the 100 to 250 probably

Ok, thank's so do you think the blue's are more important or the whites?

 

[saltyfilmfolks]

imo no. I set my led ratio to taste by eye. make the tank look good to you.
depending on what kelvin your white is(probably 8,000 to 12000, although some are less) you should have enough blue in that. adding blue increases the color temp. and thats fine.
I do believe you need at least 8 to 10k. so its likely the led is already set for marine animals.

so if you dont have a par or lux meter. set the ratio by eye, and slowly increase the intensity and acclimate.

You will also find that you nem will move to where it is happiest with the lighting

My bta moved to the bottom area of the tank with low flow and he's never moved since. I originally placed him with higher light but he moved himself there.

They are not that picky imo. Just go with what looks good to you. I also consider them to be happiest in medium to high light.
