I tested every tank I dove last week. No CO at all, the only anomaly was one that bounced between 0 and 1 on the analox. Good times!

Meridiano is the biggest there and they do supply many. Several of the larger Ops have their own compressors, and sometime Ops loan tanks to each other. You never know the source for sure.If I'm not mistaken, the vast majority of the Coz ops tanks come from a central fill facility.
I know, it gets boring testing tanks when they all test clean - until you get the first tainted tank.I didn't test every tank, but I tested the first few and then the odd ones here and there. Every reading came out zero.
Who has failed us with tainted tanks before, even after they got a free Analox inline CO monitoring system. It was apparently installed without auto-stuff off - just an alarm that could be ignored.Yep, op was dive paradise. Tanks had Meridiano stickers on them.
I remember a few people getting hurt on Coz one year and they couldn't even find a tester to check the tanks after the fact. .
