plant tablets (terrestrial stuff)

Hello rob:

If your aquarium has any fish or other animals, they will generate
more than enough nitrates and phosphates.  It will not be necessary
for you to add any.

On the contrary, adding these compounds may cause algae problems
since the algae appear to take them up in preference to the
higher plants which you want to encourage.

You did not say what brands of tablets were involved, but
I would not use them.

If you need to add trace elemsnts (e.g., iron) there are products
which will do this without adding nitrates or phosphates.
