Koi Water

Wednesday, July 5th, 2017

This lifetime exchange of different substances between the koi and its environment goes on through a semi-permeable membrane. Semi permeable membrane stands for that a few substances only can travel unidirectional through the membrane.

Koi can not exclusively select which substances it will permit to pass across the membrane. This semi permeable membrane has been evolved over millions of years and the development has came about in natural rivers and lakes and not in ponds and koi water which means this process has assumed the conditions to that of lakes and rivers. Surroundings in rivers and lakes are well balanced eco systems due to their large size. Large variations in concentrations do not crop up. If it happens then it would be in a very gradual process over decades that allow the koi to adapt or die. But, in a pond conditions can swing decisively in as less as 24 hours leading to destruction and death.

Fluids tend to mix each other whilst they are in close contact. The fact is such that the semi permeable membrane which separates fish from its watery environment cannot avert a case of diffusion. Diffusion is a process which permits the bodily fluids of koi to be greatly influenced by the outside water. So, if you change the habitat, you change your fish. The greater the size of the pool, the more stable it is prone to be. Fish only can adapt to changes in their atmosphere in a controlled fashion and over a small range or tolerance. You may have to face these challenges while keeping koi in a pond. The maintenance of koi water should be stable, predictable and consistent.

There is no difference between koi and other fishes. They need foods just like other animals in that they require vitamins, proteins, fats, minerals, carbohydrates etc. They have restricted access to oxygen which indicates that koi must use oxygen as proficiently as possible.

Since they are in continuous contact with watery environment they also require dealing with the constant osmotic and diffusion processes that happen in watery medium. Osmosis requires energy. It is the movement of water from a place of higher concentration to lower. Energy involves oxygen. A fish also generates its own body heat besides osmosis. Koi simply could not get enough oxygen from water to execute these processes. They are also relied on oxygen from the air.

It is crucial to know that every water substances and properties (such as pH and temperature) in Koi Water tends to be at equilibrium and the state of equilibrium seldom happens in Koi water, but it is very important to note that when it happens things tend to be very hard to get there.

Water, Water

Friday, March 10th, 2017

A report this weekend about Lake Superior is both surprising and a bit disconcerting. The report indicated that over the past five years, Lake Superior, the largest body of fresh water on the planet, has lost 12 trillion gallons of water to evaporation. The news story went on to say that the Lake, representing some 20% of the world’s fresh water, has risen some five degrees in temperature. Once deep waters have become shallow and tankers carry such cargo as coal have had to reduce their weights by around 10% to clear the depleted waters. Local docks have become sandbars and owners are losing the ability to meet dredging costs.

So, where all of this has water gone? The latest weather news may give a clue (this is not scientific but it is related). In Sloth Korea a monsoon has taken six lives; in Southeast Asia twenty six more people have died in flooding in India and Bangladesh; in Uganda whole villages, bridges, farms and schools have been washed away by floods; 15 die in floods in Rwanda; and, of course, we have the damage caused buy Hurricane Humberto. There are also reports from Alaska of villagers fleeing floods as storms surges appear to be putting finishing touches on Kivalena, an Arctic island that will soon be lost to the sea.

The UN’s IPCC reported that within twenty five years, 5.4 billion people will be living in areas where water is scarce. Of course, this assumes that computer models are correct. Recent reports indicate that many of these models are actually wrong and that global climate events may occur at an even faster pace. New factors and relationships keep emerging that invalidate projections and events are proceeding at a more rapid pace.

In a book titled “Save Our Species,” author Robin Greenslade gives a litany of climate changes that have gotten out of control. Among the events he cites are: faster Arctic ice melt, the collapse of Thermohaline Circulation, the faster break up of Antarctica ice sheet, a semi-permanent El Nino, massive forest fires, desertification and flooding, rapid glacial retreat and more. Recent global events tend to support these assertions as floods and fires top many of the weather news stories. Fires in the western U.S., Greece and the heat waves this summer in Europe add credence to the dire predictions.

What is beyond reason is the still apparent lack of sense of urgency on the part of policy and lawmakers. Vice President Cheney still wants to debate the issue and the Bush administration as a whole, while finally coming around, is still reluctant to propose sweeping and drastic environmental and energy policy changes. The recent Vermont Federal Court ruling approving several states’ desire to regulate auto emissions is a start but again, time is of the importance and plans to reduce emissions that are still fifteen years in the future will suffice. As a whole, the American public appears to want change but there is a total lack of the sense of urgency.

If the world is to turn these apparent negative climate changes into an advantage, action needs to be taken now. The mass migration of populations to coastal cities, as reported by the UN, is a death march. Concentrating our efforts on bio fuels in the absence of a sound food policy is suicide. Time is rushing by the Nero and the fiddle story cannot be repeated if we want our children to live in a habitable world.

Regulating Water Temperature in Fish Tanks

Thursday, August 18th, 2016

If you are thinking about setting up a fish tank to enjoy either at home or at your office, you can expect to put forth a little more effort beyond simply filling a tank with water and tossing in some fish. There will be some special equipment required if you plan to keep the fish healthy and the tank clean for a long period of time. Most set-ups will need something called an aquarium chiller which primarily keeps the water in the tank at a consistent temperature. During the heat of the summer months, aquarium chillers are especially needed to control the water temperature and help prevent the spread of disease and algae growth. You will most definitely need one if you will be running a marine tank that will contain coldwater fish.

The system works basically like an air conditioner or refrigerator and the same principles of gas expansion and contraction apply. A thermostat control unit can be set to the appropriate temperature and when the water temperature rises above the desired setting, the cooling unit turns on. When the refrigeration gas gets compressed, it becomes cooler and the cool gas is directed to a heat exchanger where it absorbs heat from the tank water, which has been pumped through the exchanger. The excess heat is carried by the gas back to the compressor and across an expansion valve. The valve allows for a sudden pressure drop which results in the heat being transferred to the radiator, which releases the heat into the outside air by way of a fan. Finally, the cooled water is returned to the tank and the whole process continues until the tank water is at the specified temperature.

There are a few different types of water cooling systems. Thermoelectric styles are quiet, energy-efficient, and are meant to be used with smaller freshwater and saltwater tanks with a slow water flow. They are not effective on large tanks with a fast water flow. Drop-in chillers are available in a variety of sizes and horsepower. No plumbing is required so it makes the drop-in models perfect for tanks that have limited space. In-line models are used for larger systems with in-line filtration because they cool water after it has already been filtered. In-line styles require plumbing and are available in several sizes, so they will work with several sizes of tanks and are used mostly with saltwater setups.

When choosing a cooling system, one must consider the size of the tank, the additional equipment, and the temperature requirements of the fish. Marine tanks in particular often utilize equipment, such as lighting and water pumps, which generate heat that raises the water temperature. Without a system to lower the water temperature, the water can warm up too much where it can no longer hold enough oxygen to sustain the fish. The cooling systems themselves produce a considerable amount of heat, so be sure to plan for sufficient space and adequate ventilation to avoid adding heat to the tank water.

Connor R. Sullivan has been researching a type of aquarium chiller online for his office aquarium. He found aquarium chillers for a reasonable price online.

Good Water Pressure All the Time

Tuesday, May 31st, 2016

There are a number of things around the home that can really annoy you. One of these involves low water pressure. No one likes having a shower and discovering that the water has reduced to a mere dribble. And it is a waste of time standing waiting for the sink to fill slowly with water. Luckily, you can easily sort out these water pressure problems and ensure you have good water pressure in your home.

If it isn’t the supply from the water authority, then it could be one of the pipes bringing the water from the main supply across your property to your house. If you suspect this, then get in a plumber to check it out. Unless you are certain of the job it is smarter to have a plumber examine these pipes. it may be that there is dripping or it could mean that the trees are getting too big and there roots are penetrating the water storage. It may be that the piping has aged and they have began to deteriorate. Either way, they will be either causing a blockage, or increasing the friction, and the result will be a lower water pressure. If it is the base of the trees then be sure a contractor is hired to eliminate the roots and prevent this problem in the future.

If you have always had low pressure, then it could be that you have thinner pipes. The tinier the piping the more friction and the less quick the water. If this is the case, then you may decide after talking to a plumber, to replace your pipes. This is not a cheap option, but may be the only one available to you. You’ll find that if your pipes are only a ½ inch in diameter, you are more than likely to have lower pressure than if the pipes were ¾ inch or one inch in diameter. Talk to your plumber, figure out how much water you use daily, and decide on what is the best solution.

It may be a clog as the result of a substance similar to calcium. If this is the case, then have a word with the plumber when they come to clean or replace the pipe and discuss whether it be worth your while to purchase a water softener or other water purifier so that these chemicals aren’t leaving deposits in your pipes, and at the same time you will improve the quality of your drinking water.

And, finally, if there is a problem with just one of your fixtures, such as your shower, then chances are there’s a blockage in that particular fixture rather than in your pipes, in which case you will need to clean or replace the parts so that the water can freely run again.
