Per the SEClear Algaeide label you should only treat ½ of the pond at a time, as there will be oxygen loss when killing off the algae and weeds. To prevent harming the fish you should begin your treatment along the shore and move outward in bands so that the fish can move into untreated water. Wait 14 days and then treat the other half of the pond.
