I have surplus Chaetomorpha algae available for sale.
If your looking for some Chaeto for your refugium, I can ship you a quart sized bag priority mail for $20, shipping included.
I have positive feedback shipping Chaeto, and it will arrive healthy and ready to put in your tank.
Chaeto is used in a brightly lit refugium as a natural way to remove nitrates and phosphates.
You can also put it in a filter sock and tie it off in your main tank near the lights if you don't have a refugium.
Chaeto is pronounced "kay-toe" is also called Spaghetti Algae because it grows in strands like a ball of spaghetti. The algae is excellent at keeping nitrates and phosphates out of suspension, and in turn improving coral growth and reducing unwanted algae in your display tank.
Shoot me a PM if your interested.
