I have had poor growth in my tank - more or less from the start. I have had
a CO2 system in place for a month now (Nutrafin fermentation type) and I
have always used Seachem flourish additives. Lately also the pellets in the
substrate. My water #'s are fine (I think) PH 7.8, Ammonia and Nitrite 0, KH
0
GH 19(!). I have a deep 2-3" gravel bed with a layer of the fine red stuff
(name escapes me, but was recommended by LSF for planted tank) and a top
layer of coarse gravel. I have 14 red-eye tetra a dozen cardinal tetra, one
RAM and one Angel, one Siamese algae eater and one sail fin pleco.
The tank is 50 gl and the fish are doing fine. So are some of the plant,
particularly after the CO2. I have saggataria - very long and broad, Anubias
and cryptocyrenes. They all are doing reasonably well, but Amazons are not.
I attach a picture of some new ones I just added. A few days later the
leaves all had holes in them. What can I do to rectify this? I have always
used properly conditioned tap water - is it time to switch to RO?

Any advise is appreciated.

Thanks
