Power Head Fish Protection

Is there a piece that is supposed to fit over the pump intake to distribute the water flow to where it won't kill my critters?

I have two 802 Power Heads that I use for circulation in my 90 gallon saltwater tank. These were originally purchased

The Power Head concept was originally developed as a technology to be used to radically improve the efficiency of an Undergravel filter. By removing the noisy air pump and replacing it with a much more powerful water pumping technology, the actual biological capacities are massively increased.

When a Power Head is removed from the Undergravel Riser Stem, it does become an efficient water pump within the aquarium creating strong currents and helping keep waste materials in the water column longer to allow other filtration to capture and remove it. However, in this configuration, the input is not protected and the strong intake suction can cause fish and weaker organisms to be drawn into the impeller well. This is not a design flaw, since this is not the original purpose of the unit.

When a Power Head is to be used as a water pump to create currents, the input should be protected for the fish and the impeller as well. The easiest way to provide this protection is to use a Quick~Filter (A-575) to add extra mechanical filtration while protecting the inhabitants from a bare intake. This is much better than the addition of foam or nylon mesh over the bottom of the unit which in many cases will not reduce the input suction and trap or kill smaller fish and other inhabitants.

The use of reverse flow units might present another opportunity for water circulation since both have reverse circulation capacities. The water flow channels change when the lever is moved to reverse circulation, the water is actually pulled in through a grid at the rear of the Power Head. Although we do not manufacture any filter or dispersion method, a piece of foam cut from one of the AquaClear inserts (most economically an AquaClear Mini) can be used to cover the rear grid. We suggest you ensure the foam is safe for aquatic species. This foam can be used to cover the grill and protect inquisitive specimens while allowing a downward driving current from the unit.
