O2 saturation question

[FowlPlayFarm]

I am having a hard time understanding or converting mg/l to % saturation for O2. I have been measuring between 8-8.8 mg/l for the O2 in my Q tank that is 440' ASL with water temp at 70 degrees. I can not find the formula or an online calculator for converting this to % concentration. I do not know what the top level is before it reaches a super saturation solution. Is there room for improvement or am I about maxed out as to what the water is able to carry at this temperature?

Thanks,
Lester

Hi Lester,

I found some Sites about that in German.

70 degrees, I think that is Fahrenheit are 21° Celsius.

The saturation of 100% at 21°C/70°F are at 8,68mg/l.

So you are around the 100%.

8 mg/l are 92,17%

8,8 mg/l are 101,38%

If you and/or the other users are interessted, I try to post a table abot the temperature and the satutation.

There is a table of all O2 saturation grades from 0°C/32F to 40°C/104F.

There will be a correction factor of several percent for altitude as well.

Thanks KSL and Bekko that is what I was looking for I am trying to dial in my TT to conserve heat and do not want to drop the saturation to low.
