Crystal Clear Water... By Deep Blue Sea on 12/22/09
Deep Blue Sea would recommend this product to a friend
I use this product in a large media reactor (1000 gal+ system) sandwiching two layers of carbon (large particle) with a layer of GFO in the middle (so the GFO doesn't escape through the top of the reactor). The combination keeps the water in this system crystal clear. The tank is just short of 30 feet long and when looking through one end, I could read a book at the other end and I'm not joking.
As there is a lot of dust that gets sent airborn when loading in large qty's it's a good idea to load up your media reactor in a well ventilated place (ideally outside). Highly recommended for efficacy and $ value.
