Keep-A-Live oxygen infuser wanted

[Tony M]

The Keep-A-Live outfit out of Florida no longer sells them, takes calls or email and clearly is no longer in the fish oxygenation business.
I’m looking for a cheap used Keep-A-Live (compressed oxygen) rig for a bass boat livewell, expecially that stainless steel O2 regulator they were selling. If you have 1 for sale or know where I can get 1, please speak up.
Thanks

These are commercial, adjustable fish oxygen regulators:

Homemade Oxygen System
Homemade Oxygen System
This homemade fishing oxygen system entrains pure oxygen into a Rule, Inc. electric water pump through a venturi devices on the inlet side of this Rule water pump to make “millions of micro-fine pure oxygen bubbles.” *IMPORTANT – See Rule, Inc. opinion https://oxyedge-chum.com/oxygen-electricity-bait-pumps/


If you go back and look at our discussions on O2 injection on this forum, you should see the link to the UT report. it list several sources for injection components.

Thanks for the info churly,

A few interesting points about the references you offered:
I contacted Southern Aquaculture Supply, Inc. http://southernaquaculturesupply.com/store/regulators.shtml and spoke with their sales staff, This is what I learned with just phone call and a few minutes of research.

Actually this reference you provided is not an oxygen diffuser used for compressed oxygen service. Many fishermen like you are tricked by the slick marketing tactic confusing air diffusers with oxygen diffusers. The price is the 1st knock-off, the tricky wording in sales literature is a warning. If you can blow through a diffuser, it is NOT an oxygen diffuser. O2 diffusers require substantial gas pressure, Buyer Beware.

“Windbells air Stone Disc Aquarium Fish Tank Bubbler with Control Valve Oxygen Diffuser [actually a large bubble air diffuser] for Hydroponics (Air Pump and Pipe not Included) $17.00” Actually this is a large pore air diffuser, not an oxygen diffuser air diffuser used with a low pressure aquarium air-pump.

This regulator is used with compresses air: Fish Farm Regulator

Our fish farm regulator is designed for everyday farm use where compressed air is involved. Great for moving fry and larger fish around on the farm. This regulator is a single stage regulator rated at 0 to 100 psi.

A fisherman may ask, what difference in gas regulators used for compressed air vs. compressed oxygen?

*The CGA-590 valve fitting is for compressed air only.

*The CGA-540 valve fitting is for compressed oxygen only. Fish Farm Regulator #OR-01 - $90.00

The CGA 870 valve configuration is used for compressed oxygen only.

Hey Tony, I wasnt tricked by anything or anyone, I dont belive. I followed the link from the original info I posted a couple years ago. I used their recommended components including their diffuser. It is a porcelain stone and it takes quite a bit of pressure to get the fine bubbles going (regulator was showing 1500 psi when I used it last weekend). But even if I am using the wrong stone, its working. Thanks to a friend, I was able to access a O2 meter. I was able to attain 100% O2 saturation in a matter of about 30 minutes.
