Re: [AGA-Member] Potassium

["Craig Lison" <dutch_rg@yahoo.com>]

Salt and chloride is generally not good for planted tanks, silicates can 
also be problematic, the magnesium will raise the general hardness + the 
carbonate will raise the alkalinity of your water (can be good or bad 
depending on what plants you keep and what your target GH/KH is).

I would suggest some potassium sulfate instead.

I have determined that I need potassium in my tank.  Nitrate and phosphate
are at acceptable levels.  Probably have a little more nitrate than I need 
as
I have some algae.  Because of a suggestion from an article in a magazine I
got some lite salt.  I want to confirm that I can use this in my tank as it
has more than just potassium chloride.  It also contains: mostly salt,
calcium silicate, magnesium carbonate, dextrose, and potassium iodide.

What does anyone think or know?
