It has been sometime since i bought new media to try. Currently my system uses Biohomme Plus, Eheim substrat pro, biomech and Lav. On the pond, i uses bacteria-house taro rolls.These current set up is as good as it gets and the water quality is pristine.
Of course what attracted me to this new product was the recommendation on certain forum in US about its effectiveness and most importantly its modular shape. All my media are loose forming and have to be housed in nets stacked in the sump or media housing. This one however comes in a squarish cinder block and have a variety of sizes. no need for any net but you would still need a mechanical filter on top of it.
So far i tried it for one month and i must say the results are quite impressive and certainly impressive enough to surpass the king of media- Biohomme plus. As for the price of $60 SGD for an 8x8x4 block, it is pretty pricey. of course it is a relative new product and if well received, we should see prices at around $48. It is currently running in a 1200L tank with an 400L sump. Fish load is 18 large clown loach. The trick to this media is that the surface bacteria does the job before passing it to the internal bacteria of the media. check out literature on anaerobic bacteria dynamics and you will know what i am talking about. It is extremely porous and you could literally blow your breath through the block!
So my verdict is ...I will add 3 more Marine Pure to my system because of its attractive modular shape and its more than reasonable effectiveness as compared to my usual setup. Here are the pictures
