Hi,
I just received a new bunch of corals.
I am trying Acropora's again after all acros except one died the previous time.
The last time I ordered acros and they died it was probably becous the tin level was 200ug/l due to a lot of new pcv (in Europe tin is being used as a softener in the production process).
Now a year later, after a bunch of cuprisorb and waterchanges the tin is under 10ug/l
So any way yesterday I received the corals and after temprature aclamating I dropped them into a small 10g holding tank with water from my main tank a heater and a power head.
And today 24h later (all still looking fine) I dipped them for 7 minutes in coral rx (12 drops per liter) and put them on a fragrack at the bottom of my main tank.
After 10 minutes one of the acros started losing tissue (ofcourse the nicest one).
I immediately took it out and placed into a shaded area of my lps tank (same water) to make shure it did not spread to other acros.
Now 7 hours later the lights are out and the rtning acro has lost 1/3 of tissue from the base up.
The other acros still seem to be ok.
So I wonder..
Could this be from a light shock?
As I did not have a light on the holding tank (only some stray light from main tank so it went from no more than 10 par to 175 par..
Immediately after I took out the rtning acro I turned down the lights to 20%.
And now I have them in acclimation mode from 65% to 100% in 20 days just to be safe.
The lights are 3x radeon g5 costume ab+ with 50% white at peak at 80% intensity on a 40x26x22'' tank.
My current parameters are
kh 8,5
Ca 430
Mg1500
No3 10
Po4 0,08
Temp 24,6°C
Salinity 1.026
Got Monti's, stylos, birdsnest, alot of lps, Zoas and 1 (not counting the new ones) acro that all do fine and have good growth.
Now I keep my fingers crossed the other acros all be fine
