Our lake corporation uses Cultrine Plus in a 15 gallon electric sprayer that we bought from a farm supply store. We have it rigged up with a boom for the getting it put down in a hurry and have it tee off so we can use a wand sprayer when the water gets shallow and we can spray about 20 feet away. Hope this gives you an idea it has worked for us for two years with not problem just remember to drain it in the winter.
