Don't hate me! But I don't believe in selling Chaeto that I would normally throw away (it's like charging for grass clippings from my yard to me). I will sell though for $2 each bag to cover the cost of the ziploc bag and we will call it "transportation and handling" lol. Quart size bags. 99.9% chaeto but other inert contents may include but not limited to, snail eggs, various pods, asternia babies, small shoots of calurpa,,,, you get the idea,,,, if you dont want those rinse the chaeto well before placing in you sump/refugium PLEASE 1 bag per person PLEASE!
