Nice light

How has your Chaeto been with this light?

I've tried twice getting Chaeto to grow with this light and both times the chaeto has started to brown out and fall apart on me. (Not sure if it's easy to see, but I've attached a pic here.) I'm started to get bits and pieces of chaeto coming up through my return pump into my DT now.

Curious if anyone has any ideas on this.

Hey! Yea my chaeto has been growing very well! I use the LED light on the side of the refug and then the regular desk bulb light on the top for about 12 hours at night. I have a mix of chaeto and calupura.

Delilah maybe you don't need Chaeto?

When I built mine I modeled it after the Kessil H380s Spectrum. Ideally you'd have Photo Red, Red, Royal Blue and Violet (400-440nm). The UV/Violet LEDs are expensive so I just skipped them. Chaeto is growing well for me with mine.
