New here and have never tried to work out rig buoyancy as I always just had a small point and shoot housing and ambient light. I got a kraken smarthousing which I thought would be fun to shoot with. When i tested it is is very front heavy with my macro wetlense on and very negatively buoyant. I bought a tray and arms to put it on so I can get a video light going. When i searched to buoyancy on it I keep coming up with the buoyancy float arms which are pushing me past what I want to spend right now. Does anyone have any DIY buoyancy advise I can use?
