I have a pond about 3 acres in size with an ave. depth of 6 ft. Chara has taken over about 30-40% of my pond. About half remains submerged all year while the other reaches the top. What is a good technique to kill both. What chemicals are cost effective and in what form (liquid or granular)?

Chara is probably my LEAST "favorite" aquatic pest to challenge. Its presence indicates that you have very hard water (so I'd rule out the use of copper sulfate - period). A chelated copper (eg CUTRINE PLUS GRANULES) may be useful in knocking the chara-population back for a short period. However, if you continue to have ultra-clear water (my bet is that your water is crystal clear - ???), the chara will very likely return in fairly quick fashion. So, I'd also suggest implementing a plankton-inducing fertilization program (to reduce sunlight penetration) following the chelated-copper treatment. The sooner your water clarity is reduced, the less problem chara will present in the deeper areas of your pond.
