No such luck. My tapwater has virtually no phosphate,
no Potassium, 0.30 ppm Iron and 30 ppm alkalinity.
Nitrates are less than 0.50 ppm.

I can't seem to find the palm sticks. I've looked
everywhere--Lowe's, Home Depot, Wal-Mart, two Ace
Hardware stores, even a few local mom and pop
nurseries. The lowest PO4 sticks I can find are the
Miracle Gro spikes, with a 6-12-6 analysis. These
make the lilies in my pond bloom like gangbusters, but
when I added about 1/3rd of one to my aquarium (4th of
July weekend), I got a mess.

I have about 2-1/2" of substrate (Turface topped with
gravel) in the back of the tank, with about 1" in the
front. Should I build it up, you think? I have
plenty of gravel. ;)

At this stage of my foray into keeping a planted tank,
basic is about all I'm brave enough to try. I'm still
excited, satisfied, puzzled and horrified by what I'm
watching. ;) Almost nothing I've done yet has gone as
expected, but I haven't killed anything yet, so...
