Hello! Plz Help Quick - Pond Products In Tank

[ConcreteWaves]

Hello there, I bought API POND Simply Clear w/ Barley  and API POND Stress Coat - I didn't realize they were the "POND" products until after I used them in my freshwater tropical fish tank. I didn't overdose at all infact, maybe underdosed - i used enough for a 20gal tank, and mine is 29gal. Please let me know if I should change out the water, or if everything is going to be fine. Can I continue to use these products in my tank?

Pond products are generally the same as freshwater just much stronger. Too strong for smaller tanks without dilution.
 
As long as you read the bottle to make sure there are not pond specific elements, some skin products cannot be used with plec's as example, and you dose to the quatity properly your fine, my LFS told me to look for pond products as the quantity of some water treatment brands you would need for a 300L tank like mine and bigger would be ridiculous.
