Hi

I have been trying to source a supply of dechlorinator that does nothing but
dechlorinate. According to my LFS the Tetra product only contains Sodium
thiosulphate, but the label says that it will also remove heavy metals.

Does Sodium thiosulphate remove metals as well as chlorine? As I mix my
plant food in with my change water and dechlorinator I think I may be making
the iron etc unavailable in the water column.

Any more info would be much appreciated.

If you can find it, I believe Genesis is pure thiosulfate.

I've never had problems maintaining adequte iron for plants with water
treatments or even carbon or Chemi-pure. Are you seeing chlorosis?
Have you tested your iron levels to see whether you actually have a
problem? Iron in the water column must be chelated to stay in solution
so I doubt that it's available to react with heavy metal removers.
