whats going on with my tort

[kutcha]

Ok so here is a picture of my oregon tort on the back side is it bleaching STN or what the front side looks amazing the only reason i found this was because i had to move some rock work

And here is a picture of the front side i see everyday

interested in this too... could it be a flow thing?

 

[kutcha]

Well if it is then hopefully my rock work change will help

System? Lights, flow, temp, nitrates, phosphates, salinty.

Even the back side of corals should be alive.

What is the white channel on LED set at?

Do you know your alk, calcium and magnesium levels?

What is the white channel on LED set at?

It isnt a dimmable one they are just on and off the white light come on around 11-12 and go off around 6-7

I am almost wondering if it was like that when i got it cause in the picture it looks like there is green growing in the bare spots and it would take it a little while for it to grow

 

[kutcha]

Do you know your alk, calcium and magnesium levels?

Calc 425 or so alk 9.8 and mag is 1600

Is anything stinging it?

This might not be all of your problems, but it is likely very weak from dealing with tons of excess red, green and yellow light from the white diodes. Outputs closer to 30% are more appropriate for corals from deeper parts of the ocean like most colorful SPS. The SPS spends lots of energy reflecting/deflecting that much wrong spectrum. Those type of non-dimmable, non-channeled LEDs do better with shallower water corals that are used to that much red/green/yellow from the sun that does not get filtered out by the water at deeper depths.

Does the picture show the color very close to accurately? It should be deep, deep, deep blue.

Yes this is the color it was when i got it i figured it was stressed and would color up the color has acually improved since i got it but do you think it would do better if i moved it down to like the sandbed in partial shade it would help? I mean its polyps extend out were it is now and no nothing is stinging it

 

[jda123]

I have no idea. Sorry. I don't use LED on my SPS for too many reason that I care to get into to keep this thread on track, but it probably won't hurt to try. You might just be trading one issue for another - less white for less light.

Hopefully in a week or two ill be getting my dimmable unit back from the repair

 

[kutcha]

im goin gto watch that area and see if it spreads if it does i know it is something wit hmy tank if it doesnt then i know it is something that was there when i got it
