Sorry if I came off too strong.. I like the description on how you tired/held it down now.
When you just said tied down I pictured it wrapped up with fishing line like some hog tied cattle 8O
And I was not and did not mean to direct the water quality, mature tank statement at you, I was just making a blanket statement based on many posts on this forum.
So many people just buy these anemones after a LFS
tells them its ok to have them in a tank and they do not research it before hand.
Again sorry for the miscommunication Brisco.
