Ummm, no I didn't ! That is because I don't have a nitrate test kit (yet)

Thanks for your interesting information Rachel, red-bronze is a good
description of the colour in the amazons that are just slightly affected,
but the two harbii are a real sad red-brown :-!(
I think that my nitrate will also be very low, since there is only a very
small fish population in a big tank and with good growth on some of
the other plants I expect that they are soaking up any available nitrate.
So it looks like I will have to get a test kit this week and try out your
suggestion of KNO3 in little doses to see how things go.
The trouble is that in the archives there has been some discussion about
test kits not agreeing measurements one with another, so I am uncertain
what type to get.
Attention UK members on the list :-
Anyone recommend a good nitrate kit that is available in the UK ?
Or better still, some diy chemistry to cook it up myself ?!
