What is the best light setting for a reef tank with an anemone and zoanthids

[JulieZ]

My husband and I just bought this 90 gallon tank off of someone on facebook for $250 dollars about 2 weeks ago. The tank came with all of the corals, fish, stand, and equipment. We do not know which brand lights they are and do not know how to measure the best intensity for the bubble tip anemone. The gauges range in 25 power increments (as shown in an attached picture). It says wattage is 55×3. It's hard for us to read the other information because the sticker with the information is below a bar that covers it. I've read bubble tip anemones like high lighting but I dont want to over do it and "burn" the inhabitants.

try starting out at 50%. the anemone will move based on how much light it is getting either toward the light or away from or to a shaded area. i added a light and removed my glass tops to increase the light and the RBTA hid behind a rock. the Zoa i had didnt want to open. i lowered the intensity and the zoa has started opening again and the RBTA has come out where i can see it.. anyway one recommendation that i have seen is to start low and increase the light over a few days or weeks so that the corals and livestock can become accustomed to conditions. good luck!
