BTA's under Leds

[Ardeus]

Anyone else is using Leds to keep BTA's?

I have a flame BTA for almost 2 years but she has lost almost half of the colour.

That happened during the first couple of months and since then, she's been growing but not recovering her colour.

In the first months I used the fixture full power and then I reduced to half power. I've been been slowly increasing the light power since then.

I keep her under a Maxspect 160W led fixture. Can the leds be responsible for that?

I don't know if it is necessarily the LEDs, but it sounds like the light change certainly affected the NEM.

Im sure there was a change in spectrum and a change in intensity. What were they under previously? Those maxspects are very bright.

They were under a 150 Watt MH + T5 actinics.

But the nem has the same pale orange colour for over a year.

List all params/specs.
FWIW my avatar is a RBTA under LEDs, and I had 4 other BTA's under them as well in the same tank and they all did just fine.

my RBTA has been under LEDs for around 3 weeks now and has seemed to really like them

I don't control most parameters often, only salinity (1.026), pH swings and kH (8).

Calcium usually around 380 and Mag around 1200.

I run carbon and Ultraphos on the skimmer (deltec mce600)

I do a weekly 15% PWC with natural sea water. The tank has a volume of 170 litres.

3/24 - under PC lighting

Under LEDs (after like 3 weeks under them, picture taken yesterday)... there's a lot of flash in this picture... I can get one without flash if needed.

looks like it has a lot better coloration to me, and it's not stretching for more light... and that's with the LEDs turned down.

I've been using a 12xLED DIY setup in my mad-scientist experiment tank for nearly 17months. This 12gal Aquapod houses a GBTA with the color only darkening after moving from 250W of MH. I vote for light shock.

Have you changed your photopoeriod since the switch from T5? I would play with photoperiod and intensity since you have dimming capability.

When I first recieved the Led fixture I used it in full power too soon, I guess and when I noticed it was too much for some corals I reduced the power a lot.

But I've been increasing the period of 100% light and until now the anemone doesn't try to hide. She's been on the same place for over a year and growing slowly, although I feed her at least 2 times per week.

Patience... that's what this hobby is mostly made off.
