Peat is GOOD for growing plants.... Chemi Pure is bad, VERY BAD! It is VERY
efficient at removing trace elements. I tried it once (~15 years ago) and it
killed my floating water sprite. Since then, I have not used any chemical
filtrants in any of my tanks.

I am glad that its label does not mention plant tanks!

This is a good indication of the how robust java fern is. I would guess that
other plants with thick rhizomes would also survive chemipure, but only
temporarily!

If you want to grow plants, don't use carbon either.
