Has any one ever ran a skimmer with pure O2? I have a alpha 170 and I am Experimenting with O2. I am running a small diameter tube with 3 liters per hour of O2 into the ozone port. any one try this before?

true...but since it is pretty widely used, and provided by many (praxair, Airgas, etc) there is some competitive pricing

we use the stuff at work, so i will try and get the quotes we have
 
the only thing I know for sure is that it will help with PH. not sure what it will do for the skimmer performance or waste, but its worth a try to see what it does. I dont think 3 leters is enough to oxidize anything, I will increase it tomorrow and see what effect it has
 
I am seeing that my PH is at 8.35. with the normal co2 levels in my house It is usually around 8.2. with windows open it will hit 8.4.. so at 3 leters it is helping the PH after 3 hours
I know that 7 leters for humans is toxic so tomorrow I will see what 4 leters will do. I suspect that it will make my skimmer produce darker skimmate. not quite like ozone, but i think there would be some effect
 
You want to be careful not to supersaturate the water with O2 as it will lead to gas bubble disease in the fish. It will also not do very much for the pH, as it does not directly effect pH beyond any extra turbulence created from the additional bubbles that would increase gas exchange and therefore off gassing of CO2, which would impact pH levels directly ;)
 
I think this could be a potentially dangerous situation. I wouldn't want to use your stove or grill if you decide to do this ... oxygen and fire = bad.
 
This seems foolish to me. You are risking oxygen toxicity and possible pH fluctuations for basicaly no reason. There are much better and more stable ways to manipulate pH.

Stick with the ozone. It is shown to work.
 
I agree that it may have no purpose, but it was worth a try. 3 liters will not over saturate the water with 02. this was attached via ozone port on my skimmer so it is mixing in with regular air. I do beleive that 02 will have a cleansing effect but not to effect of ozone and as far as the effect on PH it could quite possibly have no effect other than the water turbulance exchanging gasses. Maybe an effect on ORP but I am not a chemist so I cant say what it does with docs or any other compounds in the water.

This is no where near any fire sources so I am quite sure there is no fire potential. this is medical grade 02 in a approved container with regulator

I agree, you can't beleive what this stuff will do to enhance a flamable situation.
 
Doubt the OP has the tank next to the stove and there's a amazing amount of people that have oxygen bottles in their home for breathing. Definitely not recommended is smoking with O2 but never stopped my mom with a nasal cannula, now that was crazy.
 
I have also seen many people smoking with 02. go figure.

02 is a fire hazzard, but so is the natural gas we heat our homes with or the car parked in our attached garage. for the record I got the 02 from my father who is a retired fireman with lung damage..... I dont have my tank setup next to my stove or Grill!

The point of the post was to determine if 02 like ozone has any positive effects on a reef tank. I am sure when people started using ozone many years ago it raised safty question or even c02 which is a silent killer in an enclosed area.

I am injecting a very low dose 0f 02 (3 liters) into my ozone port on my skimmer. This will not super saturate the water or cause a fire hazzard as it is mixed with household air from the venturie port. It is no different than using a nasal cannula- it mixes with air as it is breathed in.

Ozone does indeed carry it's own safety issues, especially in large scale commercial applications.

As the effect of O2 vs. O3, it's like comparing water to hydrogen peroxide. The O2 will not have the same effect as the O3, as it's that extra O molecule that is reactive and does the work that causes people to use ozone in the first place. Simple matter of chemistry ;)
 
Good point Bill.. I am totally not a chemist, i will stick to computer networks- much easier!

I did a little research before I tried anything with 02 and found articals that comercial hatcheries were using 02 and the fish were healthier. I couldnt find enough info about what the 02 was doing to improve the health. I dont know if it had a direct effect on the water quality
 
In fish hatcheries it's used to keep fish at a higher density where O2 exchange at the surface of the water would be inadequate to meet the O2 demand of the fish. We're talking stocking densities that truly push the limits of overstocking ;)
