Chaetomorpha is a great way of managing your nutrients in your tank. It is very effective at removing nitrates and phosphates from your tank water. It is also a safe haven for beneficial critters like copepods and amphipods. This is the good stuff. It grows very thick and stringy like spaghetti noodles. Price includes shipping. I ship this USPS Ground and it will arrive in 1 to 3 business days depending on your distance from Michigan. It will ship Monday through Wednesday so in most cases it will arrive before the weekend and not cause additional delays.
