I bought a big bunch of healthy, green chaeto about 10 days ago and placed it in my new HOB refugium. The refugium has good flow. Lighting is a 60 watt, 6500 "daylight" spiral flourescent in a clip-on desk lamp placed DIRECTLY over the chaeto. I've been leaving the light on 24/7 (I know there's controversy about this). Lately the chaeto seems to be "shrinking," getting limp and turning a bit brownish on top. Nitrates are 10. Phosphates 0. All water testing parameters are good. I'd really appreciate any advice or suggestions.
Thanks!

The very tops of chateo nearest the surface sometimes brown. i think you will be fine.
