LED help

Roggio · 02/01/2012, 11:43 PM

I recently downgraded all of my livestock from a 70g with two 150w MH down to a 34g solana due to a impending move.

I have a custom 15 LED fixture I made. 4 Cree 3w CW 1 Cree 3w NW and 10 Cree 3w running at 700ma. The first day the corals got blasted by 100% lighting for about 4 hours before I realized my APEX was not running correctly. I went ahead and bought a variable wattage DC charger at the store to serve as a temporary dimmer. I currently have the lights running at 30% power for 4 hours a day.

My hammer coral and even some polyps have not opened since. I imagine they are stressed from the blast. I'm new to the small tank world and have ALOT of live stock and do not want to kill them.

Suggestions?

Current live stock
2 black clowns
1 Mandarin
3 pepperment shrimp
arrow crab
2 scarlet shrimp
6 hermits
15 snails
1 huge snail (larger than a golf ball)
12-15 large colonies of SPS
Hammer
Chalists
hundreds of poyps
A few leathers
RBTA

Another thing I changed was running activated carbon. I also have macro algae growing in the back. I use the term growing loosely; I don't think it's grown at all in a month. The PH is also a little high due to a broken probe on my apex. I added some kalkwasser when I should not have. ( I plan on doing another water change this weekend.

The coral has only been in the tank a month and I did a 50% water change shortly before putting it in. Ammonia, Nitrates and nitrites are all at 0. the temp stays at 78' and the salinity and temp was all the same at the time of the water change.

I know it hasnt been long and I've made some big changes. I'm just looking for suggestions or maybe someone experience on acclimation timeline.

Thanks!

i would say keep it at 30% for a few weeks. I ran 14 cree leds on my 20 gallon cube at 50% and they all closed up, and the orange cap bleached out. I cut it back to 30%, after a week all the corals start opening up again. Seems like yours is a bit high so i would just cut it down a bit

Thanks for the help; it puts my mind at ease a bit.
