		Algae is often a catch-all for all aquatic plants and aquatic plant related problems.
		Filamentous algae are called many things such as pond scum or moss, and they are typically found at the surface in the form of greenish mats.
		Algae is not able to sit at the surface of the water and soak up all the sunlight it needs for photosynthesis and it cannot survive without large amounts of sunlight.

	UV Detective Links Algae in pond
		Using aquatic plants as an algae control requires that a specific number of mature plants are added to the pond to compete with the algae for the available nutrients and carbon dioxide.
		Methods of controlling filamentous algae include increased shade, reducing the frequency of fish feedings, practical water changes, and the use of chemicals or plecostomus (algae-eating fish) during the summer months.
		Filamentous algae may also be harvested and used as a fertilizer in gardens; remove it by hand or with a long bristle brush.

	Filamentous Algae
		Filamentous algae are single algae cells that form long visible chains, threads, or filaments.
		Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants).
		Often filamentous algae floats to the surface forming large mats, which are commonly referred to as "Pond scums." There are many species of filamentous algae and often more than one species will be present at the same time in the pond.

	Algae and UV Sterilization
		Planktonic algae (algae bloom) usually occurs as a result of increased levels of nutrients and carbon dioxide in pond water, combined with the energy of sunlight.
		Using aquatic plants as an algae control requires that a specific number of mature plants are added to the pond to compete with the algae for the available nutrients and carbon dioxide.

	Learn about Algae and controlling it with Coptrol aquatic algaecide
		Algae are generally microscopic organisms, are generally thought of as simple aquatic plants which do not have roots, stems or leaves and have primitive methods of reproduction.
		However some algae display primitive animal features such as motility, while blue-green algae differ markedly from plants and all other algae, in that they have a cellular structure and function that is more common to bacteria than to the plant kingdom.
		Algae live in a wide range of aquatic environments and are a natural component of most aquatic ecosystems.

	Filamentous Algae (Site not responding. Last check: 2007-10-24)
		Filamentous Algae is what most pond and lake owners refer to as ponds scum, it is green to yellow green in color and appears to have the consistancy of cotton candy.
		The ideal time to treat filamentous algae is when it is first forming around the edges, at this time it is not heavy enough to cause any oxygen depletion problems.
		If you are treating and large algae mats have already formed, it is necessary to break up the algae mats so that the chemical can get into the water, if you just spray over the algae mats, the tops of the mats will turn brown, but the algae underneeth the mats will not be affected.

		I also found that the algae eaters that I bought won't touch the stuff unless it is in its baby stage - the little seeds(?) stuck to the side of the tanks they'll eat but not the long stuff.
		The bad forms of hair algae seem to be uniquely sensitive to the bleach treatment, and they don't have spores that float in the air.
		Fortunately it is usually attached to old plant stems and the bottom gravel, and the recently grown parts of thin-stemmed plants that might not survive 4 minutes of bleach are usually free of it.

	ALGAE
		Many of the larger algae are accepted as plants by most people but the absence of highly differentiated cells distinguishes them from the kingdom Plantae and places them in the Protista.
		Nevertheless having developed the basic cell pattern of a green alga all that was necessary for the development of higher plants were variations on this pattern.
		Filamentous green algae are almost weeds, giving trouble in irrigation systems and even on the surface of wet soils and media.

		Algae is one of the most talked about topics among new pond owners.
		String algae, which may coat the waterfall, is a little harder to control.
		Filamentous type algae will flourish on waterfalls and in shallow streams because the sunlight is more intense providing more heat and light than what may be in other parts of the pond and there is a constant supply of nutrients flowing through it.

		Algae have an important role to play in the overall food chain because they convert the solar energy into energy forms that can be used as a food source for other aquatic life.
		Algae also help to increase dissolved oxygen in water during daylight hours but an over-abundance can be a serious problem at night when they remove oxygen from the pond water.
		Algae as living organisms are far too small to be removed in a conventional pond bio filter.

		What appears to some as mere green pond scum masks the intricate and beautiful world of filamentous algae, which is clearly visible to the microscopist and botanist.
		Often an indicator of "nutrient enrichment" (actually, over-fertilization because of excess nitrate and phosphate pollution in contaminated stormwater runoff), freshwater ponds, ditches, vernal pools, and springs are often choked with tangles of this multicellular alga.
		When the algae occur in highly fertile waters in thick mats, wide fluctuations in the dissolved carbon dioxide and oxygen concentrations of the water column can result in rapid changes in the water's pH, causing stress or even death to obligate aquatic organisms such as fish.

		Algae are a diverse group of simple organisms, once considered by scientists to belong to the plant kingdom.
		The green algae are common in lakes and sometimes get attention when certain types form green, stringy, often slimy-feeling masses as the result of high levels of nutrients.
		When large quantities of green algae begin to decay, it can become a nuisance, creating offensive odors and depleting surface waters of dissolved oxygen.

		Filamentous algae, which is comprised of long filaments of single-celled algae, can form dense mats covering a large part of the pond's surface (link to photo of filamentous algae).
		Other types of algae called planktonic are single algae cells, often times free-swimming that can give the water a green color and/or impart taste or odors to the water.
		The result is less algae, healthier fish, fewer toxic gases, less odor, elimination of stagnation and reduction in bottom sludge.

		Unfortunately, algae blooms prevent viewing the fish, so that sick fish can go undetected for days or even weeks.
		Additionally, as the dead algae cells rupture, they can release organic nitrogen and phosphorous back into the water, adding to the system’s nutrient load.
		Which are then available to be recycled, and the algae bloom continues.

	Major blanketweed or string or filamentous algae problem
		Robin (you might remember Robin from a previous article called "You Meet The Nicest People") in Germany wrote to me with his pond problem which is an extreme one in my opinion owing to the apparent severity and rate of growth of what I believe to be a blanketweed problem.
		My lily pads (are still trying to grow out of the winter dormant stage and are still totally under the surface) leaves are so covered with this debris that 3 plants have died, even after I have tried to gently brush this stuff off the once large leaves.
		The result of this is that in time the string algae causes the death "by strangualtion" as it were of the plant Fundamental cause of big blanketweed problem is nutrient excess as mentioned previously.
