In general, persistent algae problems involve nutrient loading in ponds. Control measures without nutrient reduction are usually only temporarily effective. Examples of nutrient reduction are exclusion of manure and fertilizers, elimination of sediment, and decreasing overabundant ducks and geese. Algae in small ponds or isolated areas can be manually removed with nets, screens or rakes. Triploid grass carp are sterile, plant eating fish.

If you are getting too much algae in your tank cut down on the lighting. Algae cannot grow without light. Plecostomus, common algae eaters and otocinclus eat algae as well as several other fish and snails.

The easiest way to permanently rid your Dissolution lab of an Algae problem would be to go "bathless". If this is not feasible and controlling Algae growth is the objective then we recommend the use of Sodium Azide.

The best thing we can do is to reduce or eliminate the amount of nutrients (phosphorus and nitrogen) from man-made sources such as lawn fertilizers, faulty septic systems, soil erosion, and phosphorus-rich detergents.

The primary type of algae found on rooftops - Gloeocapsa magma - thrives in humid environments, often appearing first on the north slope of a roof where extra shade and moisture support its growth. Algae can derive mineral nutrients from fillers such as calcium carbonate in asphalt shingles. Increased use of moisture attracting calcium carbonate fillers cause asphalt shingles to retain moisture longer, thus promoting algae growth.

The organism Gloeocapsa produces a dark-pigmented sheath to protect itself from ultra-violet rays. By the time the black streaks are noticeable, the algae usually have been growing for months or years - the result of generations of dead algae cells built up over time.

You can use ultraviolet light to control floating algae, by pumping water through a tube containing a UV light source. UV light at the appropriate wavelength and exposure actually damages the DNA of algae cells, preventing them from reproducing effectively. Since individual cells typically only live a few days, they die off by themselves without reproducing, so the water clears. HOWEVER, the use of UV light to control algae can mask an underlying problem.

lt;I would look into the possibilities outlined above. As stated previously, such algae outbreaks are common in new systems, so don't be discouraged. Continue to manage nutrient export processes (i.e.; aggressive protein skimming, water changes with good-quality source water (RO/DI), careful feeding, general good husbandry habits, and a healthy dose of patience! You can and will get through this phase if you think along those lines.

All it means if you have green water is that there are too many nutrients in the water. This can be caused by too many fish, overfeeding the fish, the wrong kind of fertilizer, or lots of rotting vegetation. To combat algae, simply add more plants, decrease the number of fish, feed the fish less or add a filtration system. Don't replace all the water with fresh water... this just gives the algae a fresh supply of nutrients. Adding plants takes away the nutrients the algae needs to survive.

There are no proven damaging effects of algae accumulation on shingles. However, the dark algae streaks are the number one appearance-related problem reported to roofing contractors. Consumers commonly mistake the dark stains for faulty shingles, leading them to complain to the contractor or manufacturer about a shingle's performance.

When environmental conditions are right for algae development, the problem rapidly expands, covering an entire roof. Once algae are present in an area, airborne spores are carried from rooftop to rooftop, infesting whole neighborhoods. All roof types, including wood shakes, concrete and clay tile, and asphalt shingles are susceptible to algae infestation. Cleaning is the most commonly used homeowner defense against algae build-up on asphalt roofing shingles, but at best, it's only a "quick fix.

In some moist areas, algae can grow on shingles. Although the algae has no proven effect on shingle life, it does stain or discolor the shingle. Commonly called fungus, this algae staining can be unattractive. The algae-containing stains can be dramatically reduced by the use of special copper granules.

For pre-existing conditions we recommend Shingle Shield Roof Cleaner, which is specifically designed to clean roofs prior to application of the roof protector strips. Other cleaning solutions may not be effective against these organisms, and may harm your roof or plants.

Nutrients - Nutrients come from fish waste, over-feeding, decaying plant matter, and dirty filter pads. Remove all leaves and other dead material from the bottom of the pond by hand or with a net. If you are not successful, use Pond-Zyme to encourage the breakdown of materials in the pond. Use marginal plants, water lilies, and floating plants to cover approximately 50-60% of the water surface. The introduction of plants also battles the algae for nutrients and will ultimately choke out algae.

In most cases algae is actually beneficial. Some theories point to algae as a more stable filtration method. Algae serves as food and as bio filtration sites. It may have many other immeasurable benefits in the aquarium. Some exceptions do exist in saltwater aquariums and should be dealt with on an individual basis.
