Pond Boss Forums INTRO Questions & Observations Aqua-shade?

Some advise stocking GC ahead of time as a preventative, some wait to see if a problem will occur. If I were you I would not worry about getting GC this year, I would plan on putting 1 or 2 in next Spring. If you are already seeing a noticeable amount of submerged plants, perhaps get the GC this year. Similarly sized ponds near you may give an indication of what to expect; this could be really useful if some have GC and some don't.
