Does anyone know approx. how much cubic feet of air is lost on a short fill of say 2700lbs. on a Alu. 80cf tank? I have a HP 130cu and read somewhere a fill of 3000lb being 440lb light would only give me approx. 90cf so I wondered if the reduction on a Alu. 80 would be proportionately the same? On a shallow dive I don't mind the short fill but I hate to loose bottom time on a paid charter. I know to tell the shop to fill slower (and I have) but it don't sink in and they won't put the tanks in cooling water. Thanks in advance!
