Pond Algae

Pond algae can turn water green, and also constrict the amount of oxygen the plants and animals are receiving.
Having a proper balance of plants and fish is an important factor. Fifty to seventy percent of the surface of the pond should be covered with plants. This will block the sunlight from reaching the bottom of the pond, and sunlight is what algae feeds off.
Submerged plants will also help slow down algae growth as they help balance the nutrients in your pond. Fish create bacteria and algae is more likely to grow in bacteria filled environments, in fact algae feeds off on fish excrement, so don’t have more fish then your pond can hold and don’t overfeed your fish.
Try using a UV sterilizer or a chemical treatment to get rid of algae.
Evil algae

algae is formed because of (needs) high temperatures, sunlight, warmth, stagnant water, things to let it grow on and carbon dioxide.

Because the plants at the bottom cannot make food (may be due to too many floating plants ) no rain...cold temperatures ... ... the plants cannot photosynthesise .. and thus not enough oxygen for fishes /tapoles and all on surface of pond ... and because of too many floating plants ... the plants that are fully submerged and cannot photosynthesize and it will have more carbon dioxide for algae to grow ...

solution: (ignore the problem ... he hex )
jun jie said put sucker fish
can also put algae eaters
tell mr sam (just kidding , can't think of anything else )
pluck out some floating plants ..

The Algae Problem.

I found out a few solutions for the algae problem:
1. Add in prawns as they eat algae( very SLOW!!)
2. Add a sucking fish( if possible i donate mine)
3. Add in air pump/Filter(need electicity)
4. Use chemical( Able to buy from fish shop)
5. Add a UV light sterilliser( Very EXPENSIVE! And need electicity!)
6. Add covering to block direct sunlight

Algae growth need 3 key factors:
1. Strong sunlight(we have that)
2. Lots of Food like fish poo, thus creating ammonia( food for algae)
3. Carbon dioxide(the pond does not have enough oxygen)

Hope this would help............

master chief loves friends

i think tha t friends are super important because they support you most when you are in the darkest times.i have learnt many things about friend ship.first of all,friends do not need to stick to each other.even married couples do not do that.second of all,secondly,we must give each other some"my special alone time"time.And last,we must not bully others by saying light hearted words over again. light hearted words+ repeating=mess with mind=bullying=unhappiness.

anybody by the name of WESLEY AU please decode this:it is ok wes i am sorry too.but whats the meaning of"plight"?

algae algae and more algae!!!

Things needed for algae to grow so rapidly:
-lots of sunshine (above 39 degree celsiuos)
-stagnant water
-water
well, i think that the algae did not grow rapidly it is just that we did not discover it. I said that, because the condition seems unfavourable, the teperature within these few days is lower than 39 degree celsious about 32 to 35 degree celsious. But stagnant water is provided for the algae to grow as there is no raining for the past few days.
