Corals wont open?

I got a galaxia, some pipe organ and duncan coral about 4 days ago and they still have not opened up in my tank? I have them in low to medium settings....added some iodine and calcium...my levels are good....all params good....did a 10% water change? I am wondering do they usually take a few days to get use to my tank and will they be ok?

 

takes some time getting use to new home

 

they wont die right? bc they arent getting any light?

 

Corals will take time to adjust to their new surroundings, this may take a few hours to many days. The reason for this is that the coral came from a LFS (local fish store) and we don't know what their water parameters are. It would be too extensive to change our parameters to theirs every time we buy a coral. However, knowing your water parameters will help. The basic ones for corals would be; Calcium,Magnesium,Alkalinity,Ph and Nitrate and Phosphate levels) along with Temp. of your tank and Sg (specific gravity).Size of tank and what type of lighting (Metal Halide, T5, or regular florescent). If I knew those basics I would be able to tell you if something was out of the "normal range" and by correcting the out of range one(s) this would help the coral adjust.
So, let me/us know and I will be glad to help.

 

also amount of current hitting your corals.. some like alot of flow some dont..

 

why not gettin any light?

 

my lighting is listed below....1.027...dont know mag...calcium is 400-420ish...0 amon..0nitrate...0nitrite....ph 8.4.......90 gallon

 

also if you are adding iodine are you testing for it?

 

i saw your lights on your sig. was asking the question because earlier you asked bc it isnt gettin any light. so i tried the 2+2 thing. and if your adding supplements , you should be testing for them also. if not, things can get severley out of whack.

 

i do test for iodine and my levels are at .04-.05
