The Reading Genie offers teachers a simple way to teach students about blends. Teachers can use a picture or small replica of a playground slide and have the sounds slide together to form a word.
Pond Chemicals. Our pond chemicals and pond treatment products include: algaecides (kills pond algae), herbicides (kills pond plants and weeds) and many different water chemistry products, pond dyes, pond chemical surfactants (makes the chemicals stick to the pond weeds better instead of being washed off).
Copper sulfate is a commonly used algaecide, but it can be lethal to fish at concentrations necessary to achieve algal control. Trout, ornamental goldfish, and grass carp are particularly sensitive to copper sulfate, and alternative algaecides should be used in ponds stocked with these species.
