Review: Best BIO media if sizes fit your needs - There are many levels of active bio media. Just like socks they come in all sizes, materials, thread count, thickness and etc. What I mean is some aquariums can do just fine with average performance bio media while others need above average performance for their sensitive fish and heavy stock tank. I fit in the later. I wish to avoid all the "my stuff works better than your stuff" and just state a couple of facts. 1. MarinePure is the only manufacturer that provided scientific proof of their claims when I did research on 5 major brand name products which I choose to accept as valid. 2. MarinePure is one of few products that offer rock shape items and undergravel 1 inch block. Why because this product can replace "live rock" IMO if you seed the bacteria properly for salt water. I have used this product in salt water and in fresh water and it is nothing short of amazing, reliable and predictable IMO. I have used it with Seachem Stability and could not ask for better results. In salt water I just laid them in the sump and in fresh water I placed them in the trays of canister external filter but being somewhat large I filled in small spaces with EHEIM Substrat Pro for maximum volume in the canister. I have used Seachem Matrix, Fluval Biomax, live rock and etc. This is my "go to" first choice now every time, It's performance has proven it's value to me.
