help i dont know what is wrong with my leather

i got a small leather coral about 3 weeks ago and the first couple hours it was fine but the next day the polyps went away and it got smaller. now the tank 2 months old and i have a diatom problem i guess it is because it is a ne3 tank

 

how big is your tank and what are your parameters?, lighting, placement, filtration, feeding, livestock.....everything

 

Welcome to 3reef buddy!

So how old was the tank when you added the coral? What are your water parameters? Based on the info you provided, you added that coral to a 5 week old tank. Probably a little too soon, since your cycle was still in its last stages.

Give us a little more info and we can work this one out. And yes your diatoms are due to the newness of the aquarium.

 

Wow, it could be so many things. They dont like direct flow at them, they love light, what are your parameters?

 

well i have a red sea max which is a 34g tank the lighting are two 55 watt t5 power compact fluorescent i have tried diff. placements in the tank parameters every thing is zero. i have about 40 pounds of live rock in their and i added some damsels early and the tank cycled very quickly and i forgot about the diatoms but the diatoms are going away now.

 

Do you have a pic of the leather. Maybe its shedding...

 

Leathers tend to shrink & close up often... and as baugherb said shedd

My spaghetti and devils hand close up almost daily and shed once in a great while..
A pic would really help...
