How old is the tank?
What are your water parameters (with numbers)?
Salinity?
It looks like you're going through a bit of a cycle there, and you want your tank to be as stable as possible before you put an anemone in there. If it were me, I'd want one more rock on the top to put the anemone in, and yes, I mean "in". If you want to make sure for your anemone to not move around, one thing that is many times overlooked is a suitable foot "hole". BTA's like to have their foot in the shade, head in the sun.
Also, from my experience, for the T5 bulbs you can put in an aquablue plus to give you the actinic look while still getting considerable more PAR from the bulb than an actinic can put out.
