Acan Lighting

[Jpaul]

I recently bought an Acan LED A104AC, I have a few acros, a birds nest and millipora, some have started to bleach. All my levels are pretty good, Ammonia, nitrite,nitrate,phosphate 0. Alkalinity 12 Calcium 480 and Magnesium 1400. I believe I had the lights on too high intensity, 100 percent. I have dropped it down to 75. Does this sound like it could have been the problem (they are white in spots, not the whole thing) and can they grow back if not all bleached?

yes turn them down !!!!!!!!!!!!!!!!!!!!!!!!!!
i would start off at 45 and rise it vwery very very slow to 100

 

[Jpaul]

Ok, got it. Didn't know how high to put these things up!

 

[jerl77]

100 is way to much but what the hell do i know i run t5 but i know that lighting is no joke so i would start very low and bring it up slow

 

[Jpaul]

Good advice, I just hope I learned it not too late.

 

[jerl77]

if they are whit its to late sorry to tell you the bad news

 

[Jpaul]

Well, there are only white spots at this point, they are not all white. Does it mean they can't come back if they only have spots that are dead?

 

[jerl77]

cut it off and it will regrow

 

[Jpaul]

Will do, thanks for the advice!

 

[jerl77]

I have the same fixture for 5 months and at this point the highest I get them to is 85%. I'm sure you know they are adjustable 5 different settings bring them up slowly throughout the day. I must say they are great fixtures IMO.
Good luck

 

[Jpaul]

I know they are adjustable, I just have had no idea on what to set them on!

 

[jerl77]

on low ha ha ha 35 % to start mABEY

 

[Jpaul]

35% it is!

 

[jerl77]

I lust purchased the A104 fixture for my 210, I love them. I started mine at 75% and everything seems OK so far?

I got a 101 on my tank and I had sps on the bottom doing great I moved them to the middle and they all bleached in a day and I was only running at 30-35% I dropped it down to like 25% so I would say start very low on the settings and keep the sps towards the bottom for now so you don't lose more. I lost 2 huge ora birds nest colonies and some other small colonies as well =/
