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.

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.

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.

Luckily, you can easily sort out these water pressure problems and ensure you have good water pressure in your home.
