Pennies in the pond

A friend gave us some water hyacinths for our pond.  Sammy plucked them for us and I put them in our pond.
Then another friend said to put copper or copper pennies in the pond to help control the algae so Sammy sorted through some old pennies for pre 1980 pennies and then he put them in the pond. 
Also the pump went out today so we have a new one on order. 

Sammy found a tadpole.  Actually there are tons of them in the pond.
