Duuno other than I keep mine in a mix of coarse sand and fine sands,
in a 60 gal tank . The substrate is 2-3 inches deep, 96 watts PC
lights and as far as PH I could not tell you...... I do run some
pieces of drift wood and also peat in the filter to get the water like
it would be in the amazon basin reigon.....Its huge, and its been
doing fine for a number of years now.....I am not much into test8iubg
waters all the time as if I do not make changes and its all fine for
moneths and years on end, then odds are it must be right....so why
take and waste time testing. Thats my view on water testsing anyhow.

I also have a madagascar dwarf lilly actually a very common miniature
water lilly that grows super in it as well. Previously I had 55 watts
of light over the tank when it only had the amazon sword, but the lily
did not do that good, so I increased wattage to 96 and now all are
happy campers. I think the sword also benefited form the increase in
wattage as well.

Can anyone tell me the best substrate, the depth of substrate and the water
conditions required for an Amazon Sward Plant?
