Hi all newbie alert here....Long story short I have a prettg good size pond that consists of a lower pond and an upper pond with a short river conecting the 2 together. Last night my kid found a bunnch of what would appear to be mosquito larve in my river. I mean ALOT! I bought some of those doughnut looking deals in the past,but if I recall right the larvae have to eat those for them to work??? I was thinking maybe some chelated copper??? Any sugestions here?? Thanks in advance... Kreg
