Hi All:

We have used Diatom Powder for a Diatom Filter for our Aquariums for many
years. (at least 20)     I have also used it in the garden as I really
couldn't see any difference other than twice the price.

Just wondered if that was the same as the pool DE?

I simply use egg shells around most plants in early spring now.
