New technologies like â micro-LNG ,â which allow production of natural gas for markets without pipeline networks, add to the need for regulators to get a firm grasp on the changing natural gas landscape. Please check this page often as we will update with the latest fracking news and research.
Temperature varies in ponds and lakes seasonally. During the summer, the temperature can range from 4Â° C near the bottom to 22Â° C at the top. During the winter, the temperature at the bottom can be 4Â° C while the top is 0Â° C (ice).
Monthly can suffice for well filtered ponds. It is better not to change too much water at a time - 10-20% is the norm. You need to be aware of the potential temperature change you will create. For example, if the pond is 10 degrees in Spring, a large 50%+ water change can be performed without ill effects.
