Looking for Macro Algae

[RCFA]

I think Mermaid fan and shaving brush are both calcifying algaes.

I have some caulerpa prolifera if you want to try it. It has never released spores on me, but no guarantees.

Quoted on the Reef shop website:

DESCRIPTION:
Shaving Brush Plant (Penicillus capitus) grow in sandy substrates via rhizoidal "root balls". Its elongated stalk and green grass-like upward branches make a nice contrast against other natural decorations and corals in the home aquarium. Like the Halimeda Plant and like Coralline Algae, the Shaving Brush incorporates a hard Calcium Carbonate skeleton within its living tissue. This Caribbean-Atlantic native is functional in that it helps in the removal of organic nutrients because it consumes many waste by-products in the aquarium. This easy-care marine plant does well in a variety of conditions. Medium light and water-levels should suit it fine. Calcium and iron are beneficial in overall health and growth. Individual specimens are 3 - 4 inches.

I would suggest some of the brown or red algae. Halymenia and certain sargassums are sometimes available locally.

Check out http://live-plants.com/ for some options. Unfortunately they don't ship to Canada, but it will give you an idea what's available.
