I sent Bob a bit of K2HPO4 to play with:

Well if you read the Sears/Conlin paper they say limit, not drop to zero and
they had low light. They deserve more credit as do many others. I just
happened to pick up the ball and run a few yards. I added more CO2 and light
and PO4. The main thing I did on purpose was add a little more CO2. Then K
then NO3. I always had PO4 in my tap (got lucky on that one).

I'm so very sorry:) Send the stuff back if your this unhappy.

Careful. Neil has reminded us that we(well okay just me,) have becomes pious
plant zealots that have run amuck. Some folks only want one sword plant in
that 75 gallon tank or enjoy stunted plant growth.
Stunted plants growth, using a P limited approach is STILL very effective
but the P is not meant to go to zero just low relative to the other

I'm not sure if your helping or hurting the Tom and Neil issue.
Neil's very correct on many issues.
It may scare many less intense plant folks off. I do not want to do that
ever. I want more folks here and elsewhere to have a plant or two or packed
to the gills.
More examples of good tanks, the better. The folks with one or two swords in
their 100 gallon(this was exactly me a long while back) tanks sometimes grow
into the planted tanks well after some time.
Glad your going to town.
It is a bit freaky when you have grown plants like Bob has for a long while
then use KH2PO4 for a little while.
