Web alarm clock for 6:18 p.m.
You are finishing the last milkfish pen at 6:18 pm, rinsing away the loosened algae and gathering your gear before leaving the pond. Set the alarm for the time you need to stop, so the final checks do not quietly stretch past 7:00 pm. That gives you a clear end point for securing the netting, putting tools away, and heading home.
Because you will leave after cleaning the milkfish pens, keep this browser page running until the alarm sounds. If you close the page or browser, the milkfish-pen alarm will not alert you; it can also be missed if your phone goes to sleep. Keep the phone awake nearby, with its volume high enough to hear over water pumps and evening activity, and use a separate phone alarm if you cannot leave the screen active.
After working around the ponds in the warm Philippine afternoon, water is the practical choice before you pack up. Take a few steady sips while returning the cleaning gear, rather than starting a full meal with wet or dirty hands. Save merienda or dinner for after you have washed up and left the pens; a small sealed snack can wait in your bag if the trip home will run beyond 7:00 pm.
