I stocked tilapia one year but found they mainly ate the fish feed more than the algae.
I had a bad experience with TP when I did initial stocking. Not much algae, so they dined on the FHM I'd put in there to feed the bass. By the time I stocked the bass, most of the FHM were gone. Bass stunted due to lack of forage, except for those relative few shooters who turned into cannibals. A costly lesson, and not just in dollars.
