Add You - Can You Have Too Much Oxygen In Your Tank?
Myth: My spouse and I shouldn't talk about money because it only leads to fights. Truth: You can't have a great relationship until you can communicate and agree about money.Larry Burkett, noted financial author, says, "Money is either the best or the worst area of communication in our marriages." After years as a financial counselor and working with marriage counselors, I know that money and money fights are the number one cause of divorce, no

Henry's law determines the maximum solubility of a gas under a given set of physical conditions, and this is the saturation level. The solubility of a gas depends on the temperature, salinity, atmospheric pressure and the mole fraction of the gas. Reference Material Download

Public speaking, whether it’s to small groups or large audiences can make a significant difference in many personal and professional fields. Many experts on the subject provide a detailed list of do’s and don’ts, and these can be useful for helping avoid some of the faux pas that some beginners (and sometimes experienced) speakers commit.I’m instead going to provide just three primary factors that will greatly improve the chances of speaking success. They are knowledge, passion and style.
Controlling the dissolved gasses is one of the most important parts of water treatment and quality. The four principal gases dissolved in water are, Oxygen (O2), Carbon Dioxide (CO2), Nitrogen (N2) and Argon (Ar).
A balance is maintained of all bulk gasses, when air is in contact with water, this is called saturation. Changing that balance between air and water results in either super-saturation and under-saturation of any of the given gases. The critical controlling factors of dissolved gases in water are temperature, pressure and salinity.
The physiology of the crayfish and fish we introduce to the water also produces super or under-saturation. If a species consumes O2 then under-saturation will occur and produces CO2 creating a supersaturated environment of CO2.
The ideal environment in aquatics is saturation, being the balance between air (not O2 but the air we breath, air only contains on average 21% O2) and water. Or super-saturation of the primary gas the species needs, in this case oxygen and for plants this would be Co2
The key question now is; How do we achieve a saturated environment that is constantly changing with the addition of feed and the species growth? Taking into consideration the larger the species grows, more feed is required adding to suspended solids, more O2 is needed (BOD we will talk about in another issue) and more CO2 is produced?
First we need to deal with the bulk gases we dont want (nitrogen and argon) and then we need to look at species requirement and tolerance.
To do this we will rely on the basic principals of gas transfer. This theory relates to the process where the gaseous form of a compound is dissolved into or driven out of the water. Firstly the gas moves to the gas-liquid interface where the gas molecules diffuse through the laminar gas and laminar liquid films. After this the gas is completely disolved and becomes part of the water or liquid.
The rate at which gas is transferred from air to water or out of water is proportional to the area of the gas-liquid interface and the difference between saturation concentration and the actual concentration in the water. This dictates the direction and rate of gas tr4ansfer at the gas-water interface.

Networking and making business contacts is one of the toughest aspects of running a home-based business, but also one of the most successful to develop your business. One must constantly find creative ways to meet new people and introduce them to your product. If you are working from home with small children around this becomes even more difficult. Networking online may be the answer.There are several ways to network online. One of the most inexpensive is to visit message boards (for an exa

I realize too many adults who discovered the Internet late in life, I am preaching to the choir in this article. Please simply ignore it if so.If you are one of the ones who, like me, found it hard to “find oneself” early in life or to even know what my “voice” was, then you might be able to identify.I had not been a good student in school and was working, unhappily, in my father's real estate business in a small Mississippi town. It was not a good scene for me.I somehow stum

Pharmaceutical product development covers a wide spectrum from preclinical test to clinical development, on to product launch issues and other activities related to pharmaceutical product development. There are various unique pharmaceutical product development programs, for large pharmaceuticals, small pharmaceuticals, biotechnology companies or medical device companies. With a large-scale infrastructure, committed project teams, cross-functional therapeutic units and new technologies, there are

Hydroponic gardens consist of raising plants in a growing medium other than soil. Most times, this means suspending a plant's roots in a tray of water that is concentrated with nutrient solution. The roots then absorb the essential nutrients that they need in order to provide maximum growth. Because of this, hydroponics gardening plants generally utilize the nutrients more efficiently and then produce bigger blossoms and larger yields. By doing some research online, you can find several successful

From Henry's Law we can determin the rate of dissolution of a gas into water is proportional to:
The difference between actual and saturation concentrations of the gas in solution
The area of the gas-liquid interface
The thickness of the liquid film
The volume of water into which the gas is entering
The diffusion coefficient.
So, in the end of all that I believe that you can have too much Oxygen in your water which will create an imbalance of the other gasses which in turn will mess up the chemistry.
For example; The more Oxygen (o2) you have in your fish tank the less room for Carbon dioxide (Co2). Which means that the Co2 will gass off or be "pushed" out of the water and the result will be your pH. will rise. Also this type of environment is not ideal for your favourite aquatic plants.
The opposite also applies in general without quoting the exact sciences. I may do another article regarding the relationship between Co2 in your tank and the pH. next week.
So stay turned!
