Meadowlark,
I would say if they are half as good for most as they are for you, they sure beat nuking your pond with repeated applications of copper products that build up in your sediments, and end up marching up the food chain. If that means you end up with copper in your system because you eat the fish in your pond I'll take a biological solution any day! 
OK, now the subject broadens to �biological weed control�, rather than simply tilapia and/or grass carp and goats.
Yes goats�!
I asked my DIL this week who had mowed and weed eaten the � acre pond on the back 40? No weeds � no willows � no cattails
She said the Boer goats keep it clean.
Since �our� ponds belong to my son, and I am the lowly sharecropper, they allow NO chemicals in the ponds.
So, the next step is to fence off the house and turn the main pond into another goat pasture. The goats don�t like the water so no problem as with cattle.
I am in agreement with Cecil as to biological weed control.
