No luck with Chaeto.

[Kanshi]

Any recommendations on a macro other than Chaeto? I've had Chaeto in my refugium for over a year. Looks good, nice bright green, but doesn't grow. I have highish phosphates and nitrates which is why I got it. I see people harvesting weekly or biweekly, mine just won't grow. Have led 12 hrs mostly red and blue.
Thanks.

Similar situation here. Not completely impressed with the refugium idea, BUT! I purchased an Algae Scrubber (Ice Cap) it’s constantly growing algae. Have now done both…stickin with AS.

It took me almost a year before my Chaeto took off. I wouldnt give up on it just yet.

Raise the chaeto to the surface with rock or eggcrate. Use a bright pink horticulture light like this:
Waterproof 100W LED Grow Light Full Spectrum, New Technology COB LED Grow Light, Natural Heat Dissipation Without Noise, Suitable for Plants All Growing Stage Indoor or Outdoor. https://a.co/d/9qnCUlY
