PRO-O2 GUIDE FOR USE OF RECREATIONAL OXYGEN SYSTEMS
- When installing the regulator on the Pro O2 Oxygen Bottle, make sure that the fitting is “Wrench Tight”. The fitting should be snug so that Oxygen does not leak. Open the bottle with the top handle and make sure that the air pressure gauge is between the red “Refill” and the green “Full” marks. Based on where you get your bottles filled will be the determining factor of how much O2 is in your bottle. The gauge is an accurate representation of the pressure within the tank.
- All the Aluminum Bottles have marks stamped on the tanks themselves. There is a DOT-3AL105 stamped on the bottle and this is referring to the Department of Transportation. There will be the serial number of the bottle stamped and then there is a date in the form of two digit month “triangle” two digit year. This is when the bottle was manufactured or tested. These bottles are good for five years from that date then they will need to be tested or re-certified.
- As you turn the dial on the regulator from 0 to the setting required, you will begin to see a fine bubble emanate from the stone’s pores. This almost looks like smoke in the water based on how fine the bubbles are. We sell Fine Pore and Ultra Fine Pore diffusers and like anything, the finer the pore the higher the cost.
- The setting on the regulator will depend on a few conditions. How large is the live well, how much bait or fish you are keeping, and the water temperature? When the water is cooler, less oxygen is required. This can be controlled by adding ice packs to the water or by ambient temperature.
- We recommend the following as a guideline. Your water conditions will vary and you must work out the settings that are right for your situation.
- 2 Quarts of shrimp or 2-3 dozen croaker 1/32 liters per minute.
- 4 Quarts of shrimp or 4-6 dozen croaker 1/16 liters per minute.
- Bait over recommendations 1 and 2 should be 1/8 – 1/4 liters per minute.
- When the water is warmer than mid 70’s, increase the oxygen flow double the recommendations. You should never have to use more than 1/4 liters per minute. Make sure to add fresh water to the live well from time to time to allow for the displacement of ammonia that is built up over time from the excrement of the bait.
- Always try to keep saltwater off of the system and rinse with freshwater when possible. In addition, try to keep water from getting into the relief holes on the regulator as this leads to internal corrosion. We recommend a gallon bag placed over the top of the regulator and valve when possible keeping the exposure of the saltwater to a minimum.
- When installing the ultra fine diffuser we also recommend using silicone to adhere the plastic base to the bottom of the live well. This helps prevent the stone from bouncing and possibly cracking when exposed to rough conditions or road travel.
- HOW LONG WILL MY CYLINDER LAST FULL OF OXYGEN?
This depends on the amount of O2 that is transferred into the bottle at the time of filling. Most shops only put 1000 to 1500 lbs of O2 into a bottle. The Cylinders are rated for 2015 lbs but you will rarely find someone to fill that much. Based on our experiences, the chart below can be used as a guide for the real world.
- D Cylinder (Most Common)
- Flow Rate of 1/32 – 100 hrs,
- Flow Rate of 1/16 – 50 hrs,
- Flow Rate of 1/8 – 25 hrs
- CAN I USE A MEDICAL CYLINDER FOR MY SYSTEM?
A person can do whatever they want but, if the cylinder has a medical grade (standard CGA870 post valve) the common practice is to require a prescription to fill. Since most welding and bait shops do not carry medical grade O2 or fill these types of bottles. We do not advocate anyone to use these types of valves for recreational Oxygen Systems. We only sell Standard Industrial CGA540 valves.
