re: hard water plants

Mr. Miller,

I checked again for NO3, results are 0ppm.
My test kit isn't great though, I am ordering a better NO3 kit along with a
phosphorus kit, something is better than no kit at all I guess.

I assumed having phosphates because I have  increased fish load over the
last weeks to a moderate level and tried not to underfeed flake food, which
is a habit of mine.  Not sure what the deal is with as much food as the fish
can eat in 3 or 5 minutes, if mine do not eat the food in 30 seconds or less
I believe I am overfeeding, you think?

I do have a couple Jobe's in, couple under chain sword, amazon and Nymphaea
Stellata.  These plants are doing ok, but not healthy and pearling the way
they should.  The Jobe's are only 13-4-3 though, or something like, may not
be able to get their fill on anything but N with those.

BTW, I can get some Flora Care Plant Gro, is that Hagen?

Phosphate can very quickly fall out of solution in hard water.  As

it just acts like a generic "nutrient problem".  Aphosphate shortage

phosphate the difference was evident inhours.The only aquarium fertilizer I

phosphate, and you can use those to treat specific plants.  The reactionfrom
plant spikes isn't usually immediate.Roger Miller
