Seachem Matrix Bio Media 250ml

Purchased it to help treat the new tank syndrome. It really helps to limit the ammonia level and helps to clear up my cloudy water faster.

I used since longtime looks like doing nothing. waste of time money and space in filter.

came in this little bottle very misleading

Very nice so far, its not as big as I thought

This is approx. 10mm pieces of pumice which is one type of volcanic rock mined in western USA states. If you live in those areas it’s very inexpensive, but living in eastern areas of USA, shipping can be extremely cost-prohibitive. I use pumice for my succulents (I have amassed an extremely large collection—hundreds). I order it in 3-gallon bags from General Pumice for around $30–the majority of that cost is shipping which is included in the price. That same 3-gallon bag would cost approx. $6 if I lived closer to where it is mined. It comes in a variety of forms—almost powdered tiny granules for making your own DIY exfoliating products (just add it to your body or face wash and viola!) and many other sizes and forms. So if you have a lot of tanks, this will save you a lot of money. I’m not affiliated with the company in any way; I’m just a grateful and loyal customer. In my opinion, these tiny jars are a huge rip-off. It’s a great product, just exorbitantly over priced.

works great!

Best filter media by far. Get a media bag!

Looks like pumice but much better. Great bio-filter that can support anaerobic beneficial bacteria colonization. Controls ammonia, nitrite and nitrate. No need to replace. Just rinse it of gently as needed. You wont disturb the bacterial colonies

I bought this and I dont see much results. I think Im going back to the usual dark charcoal filters.

best price than any other store
