Interesting quick glace at the articles posted by Bulk Reef Supply on the best carbon. Based on this article
http://www.pets-warehouse.com/carbon.htm
- it states that the best carbons are lignite and rough shaped.
- second best carbons are bituminous
- the worse carbons are all pellet shaped.
Based on the product descriptions of the lignite and ROX:
- the lignite being sold is rough shaped
- the ROX is pellet shaped
- the ROX has both lignite and bituminous properties
Does the pricing and product description contradict their effectiveness in the articles?
