That depends on how it is mixed. Most fill with O2 then add air. If it isn't blended before filling you do need the tank to be O2 cleaned. Even if using a 32% mix the pure O2 is used first. Do they not bank nitrox in your area? Regardless, you'll have to find somewhere that does PP blending EVERY time you fill your tank or that O2 clean sticker will be worthless after the first place that doesn't do it... |

For me having my tanks O2 clean is serious peace of mind. |

Depends on your AO, but PP is very common here [TC/WPB], not an issue. I like getting the max benefit best mix for a particular dive. |

26ish tanks didn't happen overnight. Mostly steel tanks PST 72s , 95s, 104s, Faber 75s and 80s from the 1980s . Some AL 80s ,50s, 30s,40s,19s,and 6s. Have my own Bauer Capitano 6cfm 5000psi compressor. Bought on EBay , CL, yard sales ,and word of mouth. Wow! Sh&&ton of tanks. I just picked up a LP72 for $10. Norris galvanized. Forgot how pleasant they were to dive with. Last one I owned was in the 90's. No compressor, but fortunately, my shop gives me healthy fills. Now I am searching for a companion for it. 2 AL100's 2 AL80's 1 LP72

Up here in North Florida, everybody banks 32% and leans it out from there with regular air. If you call far enough ahead, a lot of places will mix up whatever you want and have it ready. My deco bottle is O2 cleaned for when I take my ANDP class early this year, but everything else is not. Whenever I get to the point where I'm using 80's for deco too, they will be O2 cleaned. I couldn't tell you the last time I dove a gas mix other than 32% here lol |

I couldn't tell you the last time I dove a gas mix other than 32% here lol Don't get me wrong, no problem with banked gas. There is one shop here banking 34%, which is the preferred mix for local diving. I used to get 38-40% and top off with air for subsequent dive, yielding 30ish%, but that initial fill was too limiting. Oh, and to keep pertinent, I picked up another LP72 today for $30. The same source has another 3, but I cherry picked it for now. I know, in the back of my hobo mind I will be back 
I think these things are finding me, not the other way around. |

I prefer a leaner mix too if I'm going closer to 130, especially being that 99% of my diving is cave diving. Kinda paranoid about CNS hits honestly. |

3 steel HP 100
1 steel HP 120 3 AL 80 I have a steel LP 72 that needs a hydro I use the 100s for nearly all of my diving for 30-80 fsw. The 120 gets used for deep 80-120 fsw or spearing/lobstering. When I'm lobstering in less than 20 feet I get 2.5 hours of bottom time with the 120. The steel tanks always get nitrox. Having the larger capacity allows me to actually take advantage of the increased bottom time that nitrox allows. I do not do deco diving. The Aluminum tanks get used for teaching in the pool or shallow check out dives. When I had my own boat I kept one on a down line at 20 feet |

10 to 12 free fills is common. Quote HistoryQuoted:

Question: at what point does it make more sense $ wise to buy your own tanks, via renting? My dive shop does free fills for life on any tank bought from them. So buying makes sense. Deals like that aren't uncommon. Interesting. Will have to ask about that at my LDS. 10 to 12 free fills is common. The shop I'm out of does free air fills for a year or $6 nitrox fills. |

I know of a few that will refuse to fill them. Just making a list of who does and does not locally for when I am rambling. |

Cheap way to get into steel, fill problems aside. I paid $10 for one and $35 for the other - both had been dormant for 20+ years with some rust inside - no pitting. Born on dates are early 70's, Norris tanks. I put newer K valves on them, peeled off most of the old timey tank insignia that scream 'don't fill me I'm ancient" My shop has another facility in wpb, so I have some options. I am switching to these for now. |

If they are clean and pass hydro, I don't see the problem.

Old steel is fine if it hasn't excessively corroded. Old Al is fine too if it isn't the bad batch of luxifers. Most shops can eddy current the neck on AL's anyways and detect any micro cracks, that should be a part of the annual viz check. Don't ever let them try and eddy current a steel tank neck with a set-up for an Al tank. They will all appear to fail when they are fine. |

They will all appear to fail when they are fine. it's not about whether the tank is current or not, it's simply someone not understanding what 3aa is. The ones that will not fill old steel tanks will lump the 3aa with old aluminium tanks and simply will not fill - their shop, their rules. I understand reluctance to not fill old aluminium [not talking about the problematic luxfers]. Refusing to fill a current, older steel tank is ignorant, but their shop....blah blah. |

I don't have this problem, I am buds with the city FD and I fill my own. I haven't got a shop fill in over a year and that one came with the hydro.
