| diatomaceous earth |
A fine, siliceous (made of silica) "earth" composed mainly of the skeletal remains of diatoms (single cell microscopic algae with rigid internal structure consisting mainly of silica). Tests prove that DE leaches unacceptable amounts of silicate into the water for fish health. If used as a filter substance, a silicone removing resin should be employed afterwards.

| diatomaceous earth |
A fully inert, non-volatile substance sometimes recommended as an alternative to traditional chemical treatments for controlling a number of insects and other pests, including Soil Mealy Bugs. Diatomaceous Earth (DE) is made from the skeletal remains of diatoms, a microscopic form of algae. When processed into DE, these skeletal remains form razor-sharp particles which cut into the soft bodies of small insects. While controlling insects, DE does not harm African Violets.
