iodine question

i recently purchased a pulsing xenia colony and a small frag from a fellow reefer. it was pulsing in his tank, but wen i bought it home and put it in mine it doesnt pulse. it comes to life, meaning its open waving with the current and the lil feathers stinking way out, just no pulse. i heard something about iodine, do i need to get iodine? wat brand would u receommened? also i guess i need a test kit, any ideas?

 

Never ever ever add iodine to your DT... What are your params, Lighting?, placement?

 

iodine can be dangerous and is generally regarded as unnecessary for dosing... particularly if you do water changes.

these things pulse in one tank and not the next... I believe this is still an unexplained phenomenon...

 

125g
ph 8.0
nitrates and nitrates at 0
lightin=t5
i have the frags place as high up as they can, with medium to high flow, and yes i did turn off the powerhead and they dont pulse

o really? i heard iodine was the problem... wat about calcium? im new to coral but this is the only coral i plan to keep i am definitly not buying any other
also its been in the tank for about a week, mayb it jus needs time?

As Peredhil stated Xenia can be funny , dead easy for some it grows like a weed and needs constant pruning , yet in other tanks it wilts and dies off

I have done a lot of reading into this subject and cant find any definitive solutions
sure some suggest low iodide levels can cause this . Iodide is the safer form of Iodine used in some reef tanks ( and Ill say if you have a test kit then dosing Iodide is a possible option for you - Carbon removes it so if your using Carbon and have the test kit, its worth considering just dont add if your not testing for it )

I have also read that PH lower than 8.2 will cause a previously pulsing Xenia to stop pulsing , but dont have any personal experience to support that.

yea wat about iodide? should i add some? and yea i plan to get a test kit also
n no im not running carbon

 

why is the iodide safer to use than iodine and will the carbon remove the iodine as well?

This is very good reading on the subject have a read of this and consider.

o wow dat was a good article, so i guees iodine is not such a good thing, does that go for iodide also?

 

Yes carbon will remove Iodine

Im not a chemisty expert, but have read that Iodide is the most bio available (its the Ion that is utilised) by the organisms that use it

and if this guys says its safer, Im happy enough
