hey i have a bubble tip anemone i had gotten a year ago. It bleached when i first put it in and now its white and still eating about every three days to every other day. is there anything i can do to improve its chances??? by the way lighting is supplied by a PFO 250 watt pendant running a XM 10 000k bulb. All water specs are within reef levels. calcium is a little high at 480ppm but everything else is good. when expanted its about 4 inches across. Still with green tint on tips of tenticles.
