It's Week 24, and this week we are talking chemical filtration which is the practice of using various medias to remove unwanted elements from the tank like color pigments, odors, phosphate, carbon dioxide, ammonia, heavy metals, accidental toxins, and a variety of other contaminants. We'll explore activated carbon, GFO, resins, CO2 removal media, and zeolites . We will share what they are for, some performance data as well as some of the various methods of implementing them in the aquarium. All of these medias are effective and safe but almost every experienced reefer will tell you limiting the amount of medias to those you find particularly valuable are generally a good idea for the tank because they all have some unknown or unintended effects on the water chemistry. for the most part there just isn’t a better replacement for a solid water change schedule but these medias have some undeniable results and why so many reefers use them as part of a large component of overall tank maintenance schedule. So follow along and let us know which chemical filtration media you would run in the comments area below! *Legal Stuff* The purpose and content of this video is to provide general information regarding the products and their applications as presented in the video.
