Feed all fish a quality fish food for good health. Submerged oxygenating plants and surface-leaved plants work to clear and balance the water.

This will cause large nutrient blooms and threaten the aquatic life in your pond. Part One deals with construction, plants and care. Part Two is devoted to the wonders of lilies and lotuses with full-color photos. Written by Perry Slocum, one of the best authorities on water gardening, along with Peter Robinson of England and plantswoman Frances Perry of the Royal Horticultural Society. The 160-page book tells how to plan and maintain a healthy water garden also helps troubleshoot problems.
