I know absolutely nothing about this product but I checked out their website and have these comments:
If you look at the thing....it hangs INSIDE THE TANK. According to the website, you need the pro model which measures 24" x 7.5" x 4.5". Are you sure you want some black box that big inside your tank?
The picture tends to indicate that the magdrive pump is sending water up a pipe which has a "T" in it. If so, that means that some dirty water gets sent straight out to the tank without ever touching the protein skimmer
Additional point on the protein skimmer. This unit is feeding the protein skimmer water from the bottom of the tank. Where are the majority of the hydrophobic skimmable materials going to be? Obviously, at the surface of the tank. This appears to be a second major design flaw. I could easily see a problem with protein scum on top of your water blocking both light and Dissolved Oxygen because this unit has no way of taking the dirty water from the surface.
Points 4 and 5 are laughable.
Point 4....It is best to run carbon actively. However, not everyone can do that and are forced to run it passively. This carbon pack is probably the most passive design that I could imagine. The whole back of the pack is stuck against the back wall of the filter....how can water flow through?
Point 5....Biological filtration
. Yep, that will work. Detritus will accumulate on the sponge and rot producing Ammonia. Bacteria will convert it into Nitrate, then other bacteria will convert the Nitrite into Nitrate. Then because it looks darn near impossible to clean that sponge, you have put nonstop Nitrate factory into your tank. The goal of Biological Filtration is to absorb Ammonia that your fish and inverts produce....not create it's own Ammonia.
