Review on 🐠 Seachem Matrix Bio Media 250ml: Optimize Aquarium Filtration with Top-Performing Media by Lynn Martinez

I bought this product after using 3 or 4 different brands/types of media and this is by far the best. The pebbles are larger than I expected, but the bottle says it never needs to be replaced and it can be rinsed out without depleting the entire bacterial culture. I used MicroBacter 7 to cultivate the medium for two weeks and had absolutely no problems with nitrate or nitrite levels. When it gets dirty I rinse it off with cold tap water and it doesn't seem to mind at all - it still detoxes well after rinsing. Highly recommended.
