in a pond can a water plant turn the water green?

Answer 1

The key to healthy clear water is to achieve a balance between the various inhabitants. The plants absorb mineral salts and carbon dioxide from the water and, in the presance of sunlightr, create food materials and oxygen. The fish absorb oxygen and release carbondioxide through their gills;apart from their aesthetic attraction they feed on such pests as water-lily beetles,aphids and caddis flies. They also fertilize plants with their excreta.
So long as the plants- particularly the sub emerged oxygenators get plenty of light and have to compete for minerals, the microscopic algae that make the water murky will have little chance to thrive. On the other hand there must not be too much light in relation to the number of oxygenators. It is vital, therefore, to carefully work out the number and size of the pools inhabitants. There cannot be too many under water oxygenators, especially in the first year or two; after that, any surplus can be removed. But floating and deep water aquatics such as waterlilies must never cover more than about half of the ponds surface, so as not to create too much shade.
A common problem is the growth of algae. You can easily remove the filamentious type - blanket weed by hand or with a stick, and flooding over the pond gets rid of brown or green floating scum. But the murky green water indicates that there are too few underwater oxygenating plants to compete for the available light and minerals or that too little shade is cast by water lilies. Correct these causes of imbalance, and then if necessary use permagnate of potash to clear the water. Make a saturated solution by shaking the crystals in a jar of water until they all dissolve. Stir in a maximum of one teaspoon full (5ml) of solution for every 50 litres (2cu ft) of water in your pond. The water should not turn more than the very palest shade of pink for more than a few days; if necessary repeat later on in the season.

Answer 2

No not at all, plants absorb nutrients from the water and co2 which is needed for most plant growth if the water is green it is a simple sign of good water enabling algae to grow freely. Adding a sufficiant uv filter will kill most bacteria passing through using uv light in turn making algae growth extremely difficult. Also try adding some snails to the water to eat the algae but most fish will eat small snails. Plants have nothing to do with the algae growth.

Answer 3

Go to your good local garden center and ask for something called "Auquashade" It works good. It turns the water a blue color and keeps the suns rays from penetrating too deep causing your alge bloom. Also, the surface of your pond should be covered at least 30 to 40 % with plant material. Try water hyacanth. They are cheap and grow like crazy. Too much covreage? Toss some out. They are annual in most places so after frost, get rid of them. By the way, alge in your pond is a indication that your pond is extreamly healthy, it is just ugly to look at. Good luck.

Answer 4

Algae algae algae algae nutrients not light mmm not too sure many plants can grow without both !!!
UV is a good suggestion, plus dont refill with tap water as this adds nutrients, common mistake, 70% surface cover ie lilly pads should stop the algae, feel free to put in what ever you like, plant wise just dont over do it as this may cause a fish kill during the night if the pond isn't aerated as plants take in oxygen at night.

This must surely be the best answer....

Answer 5

No, Microscopic Algae turns the water green if there aren't enough plants to compete for nutrients and there's a lot of sun-light.

Answer 6

Its usually the sun that makes algae grow and turn the water green.

Answer 7

*No!!!
Its the algae growing at the bottom of the pond, that render that color to the pond-water !!!!!

Answer 8

Too much light causes it, too little and brown algae will form.

Answer 9

yes

Answer 10

depends on how many you put in
