Depending on function, filter media falls into three main categories:<\/p>\n<ul>\n<li aria-level=\"1\"><strong>Mechanical filtration<\/strong>: Removes visible debris such as fish waste, leftover food, and dead leaves (e.g., filter pads, sponge foam)<\/li>\n<li aria-level=\"1\"><strong>Biological filtration<\/strong>: Provides surface area for beneficial bacteria that break down ammonia and nitrite (e.g., ceramic rings, Seachem Matrix, lava rock)<\/li>\n<li aria-level=\"1\"><strong>Chemical filtration<\/strong>: Removes dissolved substances, odors, water discoloration, and toxins (e.g., activated carbon, Purigen)<\/li>\n<\/ul>\n<div id=\"attachment_15339\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-15339\" class=\"size-full wp-image-15339\" src=\"https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-1.jpg\" alt=\"C\u00e1ch ch\u1ecdn v\u1eadt li\u1ec7u l\u1ecdc cho b\u1ec3 th\u1ee7y sinh\" width=\"600\" height=\"400\" title=\"\" srcset=\"https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-1.jpg 600w, https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-1-300x200.jpg 300w, https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-1-150x100.jpg 150w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-15339\" class=\"wp-caption-text\"><em>Choose Filter Media for Planted Tanks<\/em><\/p><\/div>\n<p>Choosing the right type of media is essential to create a stable, long-lasting aquatic ecosystem. That\u2019s why it\u2019s important to know how to choose filter media for planted tanks correctly.<\/p>\n<h2>How to Choose Filter Media for Planted Tanks<\/h2>\n<p>There are many ways to approach filter media selection.

So your filter media needs to match those specific needs.<\/p>\n<ul>\n<li aria-level=\"1\"><strong>Planted tanks:<\/strong> Prioritize biological media (such as Matrix, Substrat Pro); avoid activated carbon, which may absorb essential trace elements for <a href=\"https:\/\/terrariumvibe.com\/en\/Product-categories\/terrarium-plants\">terrarium plants<\/a>.<\/li>\n<li aria-level=\"1\"><strong>Fish tanks<\/strong>: Combine mechanical media (filter sponges, pads) and biological media. You can also add chemical media to reduce water discoloration or odor.<\/li>\n<li aria-level=\"1\"><strong>High-tech planted tanks (with CO\u2082 and strong lighting):<\/strong> Use filter media that ensures stable water flow and has a large surface area for beneficial bacteria.<\/li>\n<\/ul>\n<div id=\"attachment_15341\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-15341\" class=\"size-full wp-image-15341\" src=\"https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-2.jpg\" alt=\"Ch\u1ecdn v\u1eadt li\u1ec7u l\u1ecdc theo lo\u1ea1i b\u1ec3\" width=\"600\" height=\"400\" title=\"\" srcset=\"https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-2.jpg 600w, https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-2-300x200.jpg 300w, https:\/\/terrariumvibe.com\/wp-content\/uploads\/2025\/05\/cach-chon-vat-lieu-loc-phu-hop-cho-be-thuy-sinh-2-150x100.jpg 150w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-15341\" class=\"wp-caption-text\"><em>Filter Media for Different Tank Types<\/em><\/p><\/div>\n<h3>Choose Based on the Filtration System<\/h3>\n<p>Different types of filters have different capacities and flow rates.
