Hi, I'm a relatively new diver who has about 20 dives logged and am an advance d open water. My buoyancy is improving which I'm happy with but I'm having trouble with it when were close to ending the dive. I can use my breath to get down and use it as and when needed during the dive to control myself. The problem I'm having is when we come up to the 5 meter safety stop I cant seem to control it. I struggle to stay at the safety stop for the specified time and find myself floating up. I realise the importance of the safety stop and enjoy diving and want to get up to dive master but I can't figure out what I'm doing wrong and its frustrating. Any advice would be greatly received
