...RED SEA PRIZM HANG-ON PROTEIN SKIMMER.....

RED SEA PRIZM (HIGH EFFICIENCY HANG-ON SKIMMER)

Skimmers extract dissolved organic waste products (proteins) from the aquarium by mechanically removing them through foam fractionation. Efficient Skimmers such as the Prizm, remove proteins before they breakdown and pollute the water. Skimming enhances the quality of the aquariums environment as well as its appearance. The Prizm combines an efficient 18-blade Turbojet air injector together with Red Sea's patented convergent-divergent flow technology reaction chamber, resulting in exceptional skimming performance.

Features:

Skim-enhancing, convergent-divergent reaction chamber with triple-pass air flow

18-blade "turbojet" air injector - generates a constant stream of micro-bubbles in a homogenous air/water mixture

Flow regulator optimizes the skimming action for all aquarium conditions

Includes external water pump

Ideal for both new and experienced marine aquarists

User-friendly operation and set-up

COMES WITH A YEARS  GUARANTEE

please note this product has always been sold for years saying it will do a tank upto 100 gallons however red sea have recently revised this and now state it will only do upto a 40 gallon tank for fish and 15 gallons for hard corals even though the skimmer has not changed at all and is exactly the same.

please find listed below red seas explanation and so then you may decide for yourself

Further to your query regarding our Prizm Skimmers.
In keeping with the most modern research into protein skimming, Red Sea has recently led the way in defining the capabilities of its skimmers.

All of our skimmers are not rated according to the water/air throughput and the water flow through the skimmer in relation to the volume of the aquarium.

Our testing has shown that the following ratios should be adhered to:
Fish Only tank: Volume of aquarium should pass through the skimmer once per hour
Soft Corals: Volume of aquarium should pass through the skimmer 1.5-2 times per hour
Hard (stony) corals: Volume of aquarium should pass through the skimmer 3 times per hour
This rating was introduced with the Berlin X2’s and for the new C-Skim. We also implemented it into the Prizms, and re-packaged them as a result.

The specification and performance of the Prizm remains unchanged, but the rating more fairly reflects our recent lab tests. Unfortunately most skimmer manufacturers still rate their skimmers according to the theoretical throughput of the supply pump, which is largely not realistic.

We understood when we did this that we would be down-rating our skimmers. For example, the new Berlin X2’s are 50% more efficient that the original Berlin yet we recommend them for smaller aquariums.

I hope this clarifies the situation.
