EasyPro's AquaFalls Series are top-of-the-line biological waterfall filters designed to maintain the health of ponds and provide a foundation for waterfalls and streams. AL2 Large AquaFalls: For larger ponds, up to 15,000 gallons, the AL2 Large AquaFalls delivers robust filtration performance. Similar to its smaller counterpart, it offers an inlet hole on each side, providing convenient options for water intake. The installation process is hassle-free – attach the lip to the filter without the need for intricate foaming of the rock lip. Like the AS2, the AL2 is designed to be discreetly hidden in the ground, maintaining the natural aesthetics of your pond. The comprehensive package includes a faux rock lip, stainless steel hardware, and three Matala filter pads (1 green, 2 blue) with a support stand. It goes a step further by offering six mesh media bags (MB21), two 3" bulkhead fittings, a 3" PVC male adapter, a 3" PVC plug, and black silicone. Both AquaFalls filters utilize high-surface-area filter pads and media, trapping suspended debris and promoting the growth of beneficial bacteria for effective biological filtration. Promote your pond's health and aesthetics with the AquaFalls Series – the state-of-the-art filtration for crystal-clear, healthy water.
