It looks like it was filling up with fresh water. They do that from time to time. IMO
Why are you dosing iodine? Also how many leds?
What is your % and light type again?? What is running during most of the day?
How about some more WHITE???
Yup I agree your going to need more white leds. Your anemone looks to be suffering from a lack of light.
I agree with the need for additional white light and caution about adding iodine. Are you testing your iodine levels? You shouldn't add anything without testing first, and iodine is nothing to play around with. It does not dissapate as quickly as some trace elements might and there is a very specific level (.06) that you should not exceed. Adding a "drop a day" to a Nano tank is probably not a good idea. Some people never add iodine ... assuming you do regular water changes you shouldn't need to add iodine at all.
I don't know if I missed this but Ratio , although important wouldn't be my first concern.. what type of leds?? how many watts more importantly?? huge difference if he only has 30 watts compare to 400 watts of LED lighting.
The color on the nem looks fine right now, so it must be strong enough unless it starts to bleach over time..
She has Current USA TrueLumen 10" LED strips-link. 1 50/50, 1 all blue and a extra all blue that isn't and have never been on this tank.
oh wow, that doesn't look like enough lighting for ANY coral let alone an anemone...in that case that's why its reaching out like that... it needs light!
Im not sure how much these thing costs, but why don't you just get one reefbreeders LED, they are only $172.. It looks as if the lights you have are only around 10 watts.. im not sure how anything can grow well under less than 30 or soo watts of leds..
