What are the three types of filter media?

The three types of filter media are mechanical, chemical, and biological. Mechanical media remove particles, chemical media target impurities like toxins and phosphates, and biological media support beneficial bacteria that help break down waste.

What type of filter media is best for saltwater fish tanks?

The best filter media setup for saltwater tanks includes a combination of all three types. Using mechanical media for debris, activated carbon for toxins, and ceramic bio-media for bacterial colonies CREATEs a healthy, well-rounded filtration system.

What filter media remove phosphates from saltwater tanks?

Phosphate removers such as granular ferric oxide (GFO) or phosphate-absorbing resins are effective chemical filter media used to reduce phosphate levels, helping prevent algae growth in saltwater aquariums.
