This is the moment thousands of bees that survived the La Palma eruption,buried in thick ash for 50 days, were found alive
600 metres from the volcano, and surviving by sealing their hives with bee glue called propolis
@RileyOhCams Knowing you you probably did this already but check the level of the reservoir if it's empty that would do it. Also if it's really dirty that would do it to. A turkey baster is great for sucking out the old in the reservoir
