{"product_id":"hiblow-adjustable-height-pond-diffuser","title":"Hiblow Adjustable Height Pond Diffuser","description":"\u003cp\u003eThe Hiblow Adjustable Height Pond Diffuser holds its two medium-bubble diffuser sticks anywhere from 11.5 to 35.5 inches above the pond floor. The air pump only has to push against the water above the sticks, so raising them lets a Hiblow linear diaphragm pump aerate ponds up to 13 feet deep. In Hiblow's test tank, the diffuser read about 1 PSI less at its 36-inch setting than at 11 inches.\u003c\/p\u003e\n\u003ch3\u003eWhy raise the diffuser\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIn a pond deeper than 10 feet, raise the sticks so they sit no more than 10 feet down. Linear diaphragm pumps lose flow and wear out sooner when the diffuser is deeper than that.\u003c\/li\u003e\n\u003cli\u003eFor winter aeration, use the top setting. The bubbles keep a hole open in the ice without mixing the warmer water at the bottom, where fish spend the winter.\u003c\/li\u003e\n\u003cli\u003eOver a mucky bottom, raised sticks leave the muck alone. Lower them later as the muck level drops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo 12-inch medium-bubble diffuser sticks spanning 25.5 inches\u003c\/li\u003e\n\u003cli\u003eSix height settings from 11.5 to 35.5 inches, using three screw-in PVC extenders\u003c\/li\u003e\n\u003cli\u003e8 lb stainless steel base plate, 21 x 18-1\/4 inches, heavy enough to sink and stay put without gravel or bricks\u003c\/li\u003e\n\u003cli\u003eCheck valve installed on the base plate\u003c\/li\u003e\n\u003cli\u003eHose barbs for 3\/8, 1\/2 and 5\/8 inch ID tubing, plus a hose clamp\u003c\/li\u003e\n\u003cli\u003eRope for lowering the diffuser and pulling it back up\u003c\/li\u003e\n\u003cli\u003eNeeds at least 40 LPM of continuous airflow to aerate properly and keep the sticks from clogging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSetup notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLower the plate into the water on the rope.
