Carbon and Phosphate reducing media are great. However, they work exponentially better in an active setting, rather than a passive one such as what you're employing. A phos reactor isn't an expensive item, and forces water through whatever media it holds. Mine holds phosphate media and activated carbon. So much more bang for the buck without spending many! Two Little Fishes makes one, and Kent makes one too. There are others as well.
