Biological Filtration Media

Biological Filtration in a saltwater aquarium is essential for a successful reef tank. Your biological filtration system will actually do more work than any piece of equipment in your saltwater aquarium. Ensuring you have a healthy biological filtration system doesn’t take much work, but there are a lot of products that can help increase its effectiveness. From simple liquid additives like Vibrant Aquarium Cleaner from Underwater Creations to Blocks of ceramic biomedia from Brightwell Aquatics and MarinePure, you can create ideal conditions for many different types of biological functions within your aquarium, leading towards happier coral and fish.
