no dave--i was going to use the powder that can be broadcast and dissolves on contact---my understanding is that it is the least expensive and less chance of messing up with that type of fertilizer (based on ga. prices)--if either of these are wrong please let me know. i will not start until my water clears up some --new pond and is still muddy so i'd rather be safe than sorry. my neighbor uses liquid and mixes it then pours it out slowly as he paddles around his pond--he has had great success (according to him). he uses a golf ball nailed to a stick to measure his visibility. the post that followed your previous post is the sort of thing that scares me. again i don't anticipate much outflow of water in the summer if any so i plan on being careful. thanks
