So, the PO4 is probably higher than 1 ppm after the water
change/dosing and the NO3 higher than 10 ppm.  I assume you
add the KNO3 a about a day after the water change --
letting KNO3 levels drop for about a day .  So these tanks
are generally running higher than 1 ppm PO4 and 10 ppm NO3
(which are the relatively meager targets I have been aiming
at)?

I'm wondering if some of the green thumb folks can push
parameters farther, yet successfully, than some of us with
paler thumbs.  Of course, it's easy to chalk up others'
success to mystical things like green thumbs rather than
just plain good practical methods.  Maybe the green thumbs
tend to have lots more very healthy plant mass in a given
volume of water and those tanks can handle variations in
levels or increased levels better.

Well, my water change day is Friday, so after the NEC
convention at the end of the month, I think I need to start
trying this technique -- it's just too interesting not to
try.

Thanks,
