My substrate is about 50% flourite and 50% inert gravel. It varies in depth from about 2 and 1/2 inches to about 5 inches in the deepest spots. I have Malaysian Trumpet Snails to keep the gaseous pockets from forming.

My problem is that I just did a heavy replant/rescape last weekend with some great new plants that I got from some awesome PTFers in the S&S. Some of my stem plants just keep popping out of the substrate. Every day I replant them and some of them are floating the next day. How deep can you plant them?

I would say plant them as deep as you can, of course if they're tall enough to stick above the substrate. I always cut down few leaves at the bottom of the stem and plant it as deep as I can get with tweezers.

It helps if you plant them at an angle so the undergravel part is closer to horizontal. That seems to anchor them better, and the growing plant quickly straightens out to grow vertical anyway.

If you leave a couple of leaves under the substrate it will help the stems stay planted. The leaves act as a kind of baffle. They will eventually rot but then the plant can use the fertilizer so it works fine.

OK,

Thanks for all the tips. I think I'm heading in the right direction now.
