How Pond Aeration Can Reduce Pond Weeds
by: Sue McCrossin
Around the United States and other countries in the last few years, a great number of new housing developments have sprung up to house the ever-increasing population. These developments increase the amount of nutrients and sediments that wash into watersheds. Fertilizer, improper waste disposal, and soil run-off find their way into our streams, lakes and ponds and cause the following problems: algae blooms, rooted pond weeds, bacteria, low oxygen levels, increased water temperature, nasty odors, and fish kills.
A normal healthy pond keeps itself clean because it contains an ecosystem with a food chain of organisms that absorb nutrients. At the lowest part of the pond food chain, aerobic bacteria eat nutrients. The natural system in the pond works very well until excessive nutrients and run-off overwhelms the pond’s ecosystem and its ability to absorb nutrients. Once this occurs algae and pond weeds take over. As algae and pond weeds die, sink to the bottom and rot, they add nutrients back into the water, use up the oxygen at the bottom of the pond, and increase the bottom sediment. Then, as soon as sunlight and water temperature are right again, a new algae bloom and pond weed growth occur.
The Wrong Solution to Pond Weeds
Typically to combat this cycle pond owners add chemicals and herbicides to kill pond weeds quickly. Unfortunately this only acerbates the problem by adding more muck from dead vegetation to the bottom of the pond. The decaying plant material further depletes the oxygen levels. Extensive chemical usage can also result in residual build up in the sediments and fish.
The Right Solution to Pond Weeds
The solution is to increase dissolved oxygen levels so that nutrients decompose aerobically. The bacteria and organisms that live in the pond need dissolved oxygen to decompose the organic sediments, and die off if the dissolved oxygen level decreases. A different type of bacteria, anaerobic bacteria, thrive in the environment when there is low or no dissolved oxygen, and these bacteria slowly digest the organic sediments and release toxic gases into the water that kill beneficial aerobic bacteria and insects.
Anaerobic digestion of pond sediments is 30-40 times slower than with aerobic digestion, allowing organic sediments levels to increase.
The ideal thing to do to save the pond, get rid of pond weeds and algae, and increase pond fish, is to stop the new nutrients from entering the pond. Since this is not always possible, the next best thing to do is to add dissolved oxygen to the pond, which will improve water quality, allowing aerobic bacteria to decompose organic matter. This process is called Pond Aeration.
Pond Aeration – The Solution
Pond aeration increases the process of oxidizing or eliminating pollution. The best pond aeration systems work by using special equipment called diffusers. Maintaining the aerobic environment will also reduce or prevent the accumulation of organic sediments. Aerobic conditions at the pond bottom benefit all aspects of the aquatic environment, reduce algae and pond weeds, and prevent sediment build up.

influence of water temperature on fish growth
influence of water temperature on fish growth
temperature affect the survival of fish, ranging from eggs, seeds reached adult size. water temperature will affect the process of hatching eggs and egg development.
water temperature is too low (cold) resulted in the development process in the fish eggs will be slow, to maintain the optimum temperature so that the seeding of the intensive cultivation often use water heaters (heater) is commonly used in the aquarium or the like fiber. water temperature required for hatching the eggs of fish ranged between
25 to 30 degrees Celsius.
the natural rise and fall of water temperature is very influential on fish survival. changes in water temperature that is too extreme an adverse impact on the fish being kept.
consequently the fish become stressed, and when the fish are stressed then the fish will be susceptible to disease.
temperature will affect the growth rate of fish when the temperature is too low then the growth of fish kept will be slow growing, because if the temperature is low, fish metabolism will be slow and the fish will decrease appetite. temperature must be exactly the optimum range of 25 to 30 degrees Celsius

the color of pond water - water color criteria
the color of pond water - water color criteria
Criteria pond water color that can be used as a reference standard in the management of water quality is as below:
1. Color dark green pond water, which means indicate a dominance of Chlorophyceae with more stable nature of the environment and climate change because they have the time a relatively long mortality. Growth rate and relatively fast development is the potential occurrence of plankton boom in these waters.
2. Color brown pond water which means showing the dominance diatomae. This type of plankton is one supplier of natural feed for the shrimp, so the rate of growth and development of the shrimp relatively quickly. The level of stability is relatively less plankton, especially in winter conditions with the high rainfall, so the potential collapse of plankton and if not carefully managed water quality stability will be volatile and would interfere with the comfort level in the shrimp ponds.
3. Color brownish green pond water, which means showing dominance happens is the combination of the Chlorophyceae and is stable diatomae supported by the availability of natural feed for the shrimp.
Standard color of pond water as described above is a practical reference for identifying species of plankton in an attempt detection of water quality problems at an early stage. In addition to these standard colors there are some pond water colors usually found in shrimp cultivation activities, which include:
1. Color yellow pond water, which means indicate a phytoplankton species dominance cyanophyceae. In conditions like these pond waters are usually more pale colored shrimp than is usually accompanied by a decrease in appetite shrimp and if not immediately anticipated may cause damage to the shrimp hepatopanchreas.
2. Color green pond water vanished, which means indicate a phytoplankton species dominance dynophyceae impact is relatively similar to point (1).
3. Color blue-green pond water, which means indicate a dominance of blue green algae relative impact equal to the point (1).
4. Camouflage green color, in this case as if the pond greenish but basically no / less contain plankton. This happens usually in ponds which contain the seeds was very poor but planktonya fertilization activities continue, so the resulting color is the color because of the weather. This incident can be identified by measuring the brightness of the pond waters are usually very high, or to see the color of the water in a water mill was operated.
Identify types of plankton in the waters of the pond in a practical way to see the color of the water as described above to be supported by observation and laboratory analysis on a regular basis to obtain more accurate results. This activity is done by taking water samples and samples of shrimp from pond map map-whether the problem or not affected by the problem, so the comparison can be drawn.
