The fuge half of the sump in my red sea reefer is getting jam packed with chaeto. Teaming with pods and no containing no pests. I grow mine under a kessil h380 (which is awesome) and it grows densely with a healthy green color. I can ship a quart/sandwich bag full via USPS for $15 (essentially as much as I can stuff in there). I’m shipping from Florida. Add $5 if you need a heatpack. I'm only going to do a couple of these right now.
