Selling an Innovative Marine 9W light specifically designed to grow chaeto. Bought it from Algae Barn three months ago. Lightly used and have original box as well as hardware that goes with it. Paid $70 for it but looking for $35 plus shipping. It is great for small spaces and you can mount it horizontally or vertically using either the velcro or mounting hardware. Has 45 LEDs with specific wavelengths for optimal algae and other plant growth. Dimensions are 6.7” x 1.85” x .39”.
