How does pond matrix do more then other products? The microbe lift has some kind of nitrifying bacteria already in it? Sounds like a joke to me but?
Amazon had it listed az 7lbs. Of product (which now that i think about it a 5.3 gallon bucket full of 7 lbs. Of ceramic media is a rediciuolis notion)
matrix doesn't have bacteria in it, it has to be cycled. actually double cycled. first for the aerobic bacteria, then for the anaerobic. it's supposed to reduce nitrates because when the aerobic bacteria colonize the outside, anaerobic bacteria colonize the inside. they use nitrates for energy production instead of O2.
when I look at amazon's listing for a 5G bucket of matrix it says-
Product Dimensions: 12.5 x 12.5 x 19.8 inches ; 22.4 pounds
Shipping Weight: 47.2 pounds
I don't know where they get the 22.4 lbs from but the shipping weight is pretty close to what I weighed it at.
and it is made by seachem, the logo on the bucket is too small to see in the pics.
and it reduces nitrates?? Lol thought only plants and wc did that, matrix looks and feels like rocks, obviously it will hold bb but when compared to ceramic or chem stars Imo its no contest!
matrix may look and feel like rock, but it isn't. it's sintered glass. it's hollow passages throughout the entire media. which allows multiple types of bacterial colonization. which is why it's so light.
Matrix is just a cheap solution to house media, it works fine but there are better materials out there.
interesting info, I'd like to see your sources.
give this a read.

according to that, matrix in the same volume as the compared substrates, has much more surface area. granted, it is put out by seachem, but I don't see anything similar from fluval or eheim. the chinese spec sheets for ceramic media that I've seen back this up with lower surface area numbers and higher densities.
