We do a lot of large landscaping waterfalls & koi ponds with state of the art filtration systems to reduce the maintenance & keep your plants & fish in good health. The new hot thing in water features is the core drilled or bubbling boulder water feature. These are very popular because they radically reduce the maintenance associated with water features, but still give the sound that many clients are after. These features do not have plants or fish to take care of & are much less expensive.
