Thanks for the response. It's in a 20 gal high that been up and running for 18 months. I do a 10% water change weekly. I've had the anemone for almost 5 months. Lighting is provided by an AI prime HD. Everything but red, green and white are at 100 to 110%. Red, green and white are at 10%. Lights run from 8 to 8 with 2 1/2 hour ramp up/down. I'm sans test kit so not sure about paramaters. Ler me know if i can provide any additional info other than the parameters. Thanks in advance.
