The problem probably isn't your fertilizer - it's probably the Amazon's
themselves. You've probably had these plants for some months now, correct?
They were likely a healthy green when you planted them too...

Amazon's are just one example of plants that are not accustomed to being
submerged year-round. In their native habitat, they are used to being
flooded for months at a time, but not all year. As a result, they grow
yellow and weak and eventually die out completely when kept submerged.

You may want to try some true aquatic plants instead. I found this great
website that lists some of the species and gives good general info on plant
health: http://www.trueaquariumplants.com/info.asp

Remember, just because your LFS sells plants, it doesn't mean they are good
for keeping underwater! Don't feel too bad about it though - I've been
through the same thing myself! Putting Amazon's underwater is generally a
death sentence for them!

Hello all,

An Amazon Sword plant of mine appears to be suffering from
nutrient deficiency, so a few weeks ago I picked up a pack of plant
fertilizer tablets. They only had tablets marked for use in ponds, but
after carefully reading what was in it, they had all the good stuff, so
I gave them a shot.

Two or three weeks has gone by now and I haven't noticed any
change since I started popping these near the crown of the sword plant.
The tablets are large, so I've been cutting them in half before I bury
them.

The tank is a 20 long with a twin-tube 40 watt fixture. No CO2.
I add less than half the recomended dosage of Kent Freshwater plant
supplement and half the dosage of Seachem Flourish Trace when I do a
water change (each week or two). Do I just need to order better plant
food or is it something else?


The analysis by weight from the back of the tablets' package:
Total Nitrogen 20%
Water Soluble 7%
Water Insoluble 13%
Phosphate 10%
Potash 5%
Calcium 0.5%
Magnesium 0.5%
Sulfur 2%
Boron 0.02%
Copper 0.05%
Iron 0.5%
Manganese 0.05%
Zinc 0.05%
