Standard airline tubing floats when air pressure drops, pulling diffusers off the bottom and aerating at mid-water depth instead of the deepest point where dissolved oxygen is most needed.\u003c\/p\u003e\n\u003ch3\u003eAerating at Full Depth Protects Fish Through Summer and Winter\u003c\/h3\u003e\n\u003cp\u003eOxygen stratification in deeper ponds creates a warm, oxygen-depleted layer at the bottom during summer and a gas-accumulation zone under ice in winter. A diffuser positioned at full depth addresses both conditions by circulating the full water column. Weighted tubing gets the diffuser to the pond floor and keeps it there through flow changes and seasonal handling without requiring permanent anchoring.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e3\/8 in (9.5 mm) ID\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e25 ft (7.6 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCore\u003c\/td\u003e\n\u003ctd\u003eWeighted for bottom sinking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible With\u003c\/td\u003e\n\u003ctd\u003eAquascape Pond Aerator Pro and standard 3\/8 in barb diffusers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eFlexible PVC with weighted inner layer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cp\u003eConnect one end to the aeration compressor outlet and the other to the diffuser barb fitting. Lower the diffuser end slowly into the pond while the compressor is running to prevent air locks in the tubing. The weighted core will pull the diffuser down to the bottom once slack is released. Confirm the diffuser is bubbling evenly before leaving it in position. For ponds deeper than 7.6 m (25 ft), join two lengths with a barb coupler to reach full depth.\u003c\/p\u003e\n\u003cp\u003eIdeal for ponds deeper than 60 cm (24 in) where standard airline tubing fails to maintain diffuser placement at full depth, and for winter aeration setups where the tubing must stay anchored at the pond floor beneath the ice layer.\u003c\/p\u003e","brand":"Aquascape","offers":[{"title":"Default Title","offer_id":52698328793407,"sku":"AQ-61011","price":66.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/8260\/9215\/files\/aquascape-aeration-lake-default-title-aquascape-weighted-aeration-tubing-3-8-x-25-43287391797567.webp?v=1776379013","url":"https:\/\/pondsonline.ca\/products\/aquascape-weighted-aeration-tubing-3-8-x-25","provider":"Ponds Online","version":"1.0","type":"link"}
