Hi Paul, Thank you for the help.  I would replace the Chemi-Pure on an 
average of every 3 to 4 months.  The company claims it is good for 6 
months.  There were times that I left it go for almost 6 months before I 
replaced it.  Per advice from the list I am not using the Chemi-Pure at 
all now.  This Chemi-Pure thing has me thinking.  I can't remeber it 
consuming the GH is this tank when I used it in the past.  Maybe since I 
have put more plants in my tank recently the plants consumed the GH?  Is 
that possible?  I don't know.  I am trying to think of everything.  The 
problems I am having with this tank are frustrating.

I have made three water changes since I stopped using the Chemi-Pure.  
They were 50%, 50%, and 75% water changes.  The GH of the tap water I add 
to the tank is 3 to 3.5dh.  Yes, the Chemi-Pure was new when I had it in.

The Aquarium Pharmaceuticals Plant Stimulant is labeled for Pond use, but 
the company told me it is also good to use for an indoor plant aquarium.  
How true that is I do not know.  The directions say to use one teaspoon 
full ( 5 ml ) of this product for each 100 gallons of water every 2 weeks.
Now, because I have 120 watts of light and CO2 for this 55 gallon tank, 
should I be adding this fertilizer more frequently?  Like everyday, or 
every other day like the PMDD?  Should I be confident with the ingredients 
that make up this Aquarium Pharmaceticals fertilizer, or is it missing

I agree this tank gets very little light, but I can't argue with the 
results.  I have two swords in this tank that have lived under these 
conditions for 5 years and they are beautiful.  I would like my 55 gallon 
tank with all of this new (120 watts ) light and CO2 to be like this tank.
It has been suggested to me that I add one drop of iodine per 12.5 gallons 
of water to this tank everyday.  Is iodine safe for plants and fish? What 
will iodine do for the plants?  I do not know what the liquid measurement 
for one "drop" would be.  Thank you for your help.
