PMDD & UG Filter

I have two questions for anybody willing to respond, but first I
would like to point out that I don't have access to the WWW and I am
therefore unable to search past posts (at least I don't know how to
do it with e-mail).

1) What is the "NEW" PMDD formula? I don't know which one I have, but
I'd like to check before I mix up a batch.

2) I have a 20 gal tank with a bunch of "low tech" fish, one 18"
flourescent tube (Gro-Lux), a bunch of "low tech" plants placed
beside a North-West facing window. My gravel has some crushed coral
sand (to raise my pH). What would happen if I shut off my undergravel
filter? I was just wondering because some people have mentioned
plants do better without it?
