Is there a rectangular fish pond in our backyard?

Fish ponds, rockeries, and water features are indispensable items in gardens. Water is wealth, ponds are places, and fish (surplus) are spiritual creatures that store wealth. The water quality must be guaranteed to be clear and pure. To raise fish well, you must make the water in the fish pond "alive". The fish pond must use living water so that the fish pond can play the role of blocking evil spirits and attracting air. The water in the garden must be living water, removing the turbidity and leaving clear water, so that future generations can benefit from the blessing of their ancestors and have a long family fortune. There are fish ponds in gardens, but they are not living water. The water quality is turbid, turns green, smells bad, and the fish cannot survive. Over time, it becomes a failure of the garden landscape. Hengyun Garden adopts the German Kalijing ecological fish pond filtration system, which specifically adopts systematic and radical methods to deal with unclear water quality, many leaf impurities, odorous water, and fish that often get sick.
