Maxi-Jet PH pump and power head is ideal for powering undergravel filters or creating internal water movement from its fully rotational output. The Maxi-Jet PH incorporates a venturi aeration device to provide optimal aeration and gas exchange in the aquarium. A silencer keeps the venturi aeration device operating quietly. An adjustable air filter permits the user to fine-tune air volume and water mixing as desired. The intake tube adapter with prefilter screen prevents gravel or loose material in the aquarium from getting into the pump.
Showed up in practically no time and exactly what I expected! Totally oxygen-filled tank again. Reason for replacement: Power Head was purchased a very long time ago, but while away, caretakers did not replenish water level to the tank, so malfuntioned. It probably would have lasted another ten years! Thanks Folks...
