I am bumping this because the pondweed and algae have already started to come back after a brief winter rest.

From my earlier post in this thread:
"Grass carp and Tilapia sound like good suggestions, BUT...
In my area (Central Coast California) there is a high $ fee and permit required to stock grass carp and Tilapia are unavailable/illegal. Been using Cutrine+ and Reward but it's tough to get ahead of or even keep up with. Any other suggestions to keep the algae and pondweed under control?"

Any experience out there using Nautique?
Before you ask what kind of pondweed/algae, all the common submersed weeds (Chara, hydrilla, F. algae...etc.)
