I have tried lots of carbon. We have the best luck with activated rox carbon from brs. I run a cup and change it every 2 weeks for a 200 gallon sps tank. I buy a 5 gallon pail and last a few years for $227 pretty reasonable. Only down fall if it compacts so easy so need to keep an eye on this stuff or it wont churn nicely.
