Backyard Waterfall and Koi Pond Features

Use Pond Substrate Instead Of Ordinary Soil

Some first-time pool owners make the mistake of using ordinary garden soil during the construction of their ponds, and also for their aquatic plants. Ordinary garden soil is not good because it is quite dirty (it easily “pollutes” the pond), is very porous, and contains the “wrong” nutrients which can promote the growth of the algae that gives ponds a greenish coloration and “blocks” sunlight. Use pond substrate (the mud-like material found in the bottom of most ponds or streams and rivers) instead; they are less porous, are chemically “neutral”, and are most conducive to “friendly” bacteria growth.
