I agree with the "get better training" part. This is basic stuff that you
should be able to figure out on your own.
In the meantime, take a look at the intro article
How To Scuba Dive | Scuba Diving Training & Certification | Scuba Diving
under the section "Staying Longer". You'll find that decreasing your depth slightly,
say to 60 feet, is likely to extend your NDL and leave less "excess" air in the tank
(while sticking to the rule of thirds).

When diving a 32% mix using a AL 80 @ 3100 psi diving between 85-115' I get about 22-25 min before I start getting into caution zone on my computer. With a 3 min safety stop I surface with about 1200 -1400 psi.My dive partner usually does a little better than me.we're leaving a good bit of gas in our tanks.
Since running out of gas isn't the problem, how can we increase our bottom time? We would like to increase our depth too, 122-130'.
Any pointers?
