Excel killing my Anachris

Since the regulator for my CO2 system is on order, and the tank is at my house, I went in and pulled the Anachris, trimmed the little bits off the end that still looked healthy, and replanted. Then I did a large water change. Hopefully they'll survive and start filling the tank again when I get the system up and running.
 
Well, i too have anachris in my tank and am using excel. they arent melting persay, but they surely are not healthy looking. kinda off-to-light green in color, some browning spots here and there. I cant get the **** stuff to stay in the gravel though, it constantly frees itself and floats on over to my filter intake. grrr. all my other plants look fine so far. only had my tank planted for about 2 weeks though, so we will see. Any ideas on making it stay put? Also, this may be a silly question and possibly due to the Excel, but do anachris shed leaves fairly often. Even when I can get it to settle down, seems there is always a leaf or two free floating. Drives me batty. Thanks.
 
Mine didn't shed leaves at all before I dosed.

After I started, the green color faded to an aquamarine. Then within a couple days the leaves became transparent. A couple days after that the leaves were gone completely (it seems to work from the stem up... the last inch of each plant was salvageable). A couple became brown and rotten instead of the previous progression, and none of those were salvageable.

I have sand and eco-complete in my tanks. It does a fine job holding them... if you can't get them to stay, bury a little bit of the plant going sidewase under the substrate. In gravel, just keep sticking more of the plant down in there until it stays put, but gravel sucks at holding plants anyway.
