No white dots or spots and they actually opened back up the next day and have been open sinceCan you turn off the blue lights? Are there any white dots/spots on the polys?
It’s been in the tank about 2 weeks nowhow long has this frag been in your tank? agree with @diana a - a picture under white lights will be easier to see.
No changes at all tank stays pretty consistent I actually just sent a sample out to ATi and ordered new test kit because I have a horrible oneAny change in tank parameters lately.
