Phosphate in Swimming Pool Water - The basis of Algae Problems

Phosphate is quickly becoming acknowledged as the main cause of algae in pools.

Come july 1st has seen a number of the highest recorded phosphate levels in regularly across New zealand and australia. A number of this high level of phosphate has been caused by summer drought related dust fallout, and an increase in the phosphate amounts of several common fertilizers. For several years phosphate and nitrate runoff from farms has become blamed to the deterioration individuals many lakes and waterways, the problem has crossed into our swimming pools.

For pool owners, the greatest concerns from high phosphate levels are rapid chlorine consumption and stubborn, repeat algae problems.

Removal of phosphate from pool water is important to assist maintain healthy water quality. Once it has been removed, regular maintenance can steer clear of the level from being a problem again and in addition assist in better chlorine performance and efficiency, reduced chlorine consumption, and no algae problems.

Phosphate and nutrients are essential by all living organisms, including algae, to live and flourish. It is well documented that raising the swimming pools chlorine level can lead to less algae problems. But how are they related, and just what can be done to eliminate phosphate from children's pool water?

Phosphate is shown pool water from the various sources including runoff from lawns and gardens, pool fill water for example bores, dust, suntan oils and leaves. After a while, all of these sources will cause a build-up and rise in the energy phosphate inside the pools water.

Algae spores are continually being brought to the swimming pool attached with dust and instead gives off. They simply require nutrients and water to quickly multiply and turn into a menace to the pools water quality because of rapid consumption/destruction of accessible chlorine.

For years chlorine was used not only like a pool sanitizer, but it is also effective as being a temporary www.spray-away.eu.

Traditional treatment has included "shock" dosing the pool with less than six times its regular daily chlorine dose; this is good at killing off almost all visible algae.

Even if this effectively kills the algae, it doesn't do anything to cope with the situation that allowed the algae to achieve the first place. If the chlorine level returns to normalcy to algae will become growing again.

Therefore preventing the algae from recurring makes it necessary that the chlorine concentration is maintained with the advanced, the water is slowly removed through the pool, or water the weather is changed to get less favourable for algae growth.

Traditionally, phosphate levels have been ignored, while wanting to remove dead algae by filtration. Given wet algae weighs 1000 times more than the phosphate needed to feed it, it's not the most effective way to do this. Also as the algae are trapped in the filter, it releases a lot of trapped phosphate back into the water.

The most effective traditional treatment solutions are "super chlorination" or much the standard daily dose, effectively bleaching the algae white and killing it. This is as well as a "floc" with aluminium salts, before vacuuming the settled dead algae down the sink.

Getting the club recently, none of the traditional control of algae targeted the genuine cause of the algae problem. Chlorine is definitely named an effective algaecide, however does not treat the main cause of the algae problem.

In private pools there's 2 effective chemical treating removing phosphate from pools: aluminium compounds and lanthanum compounds. In sewage and effluent treatment ponds, iron compounds are employed effectively, however these are undesirable in private pools due to staining they cause.

Aluminum compounds be more effective in pools which has a higher level of phosphate build-up, inside the selection of higher than 1000ppb (parts per billion); however they require vacuuming to waste after treatment. They are going to effectively remove phosphate into 500ppb, but cannot remove phosphate below 100ppb that's needed for effective algae control. Aluminum compounds are relatively cheap, and thus suitable for elimination of lots of phosphate accumulated in the pools water.

Lanthanum goods are a potent and particular phosphate remover. They are best suited to maintaining lower levels of phosphate in pools where performance and convenience are important. These are much easier to use and apply than aluminum products and do not require vacuuming to have after their application. But you are more expensive and best suited to pools with lower than 2000ppb accumulated phosphate. One of the primary benefits of lanthanum is that its capability to form lanthanum phosphate is not afflicted with the pools water balance.

Handful of lanthanum compound will result in the phosphate level to drop below 100ppm, while concentrations of below 10ppb are really easy to maintain.

Lanthanum compounds work by lodging from the pools filter media or cartridge, slowly dissolving to lightly coat the filter media. As phosphate rich water passes within the lanthanum crystals, they chemically attach themselves towards the phosphate - forming lanthanum phosphate. Lanthanum phosphate is just not suitable as a nutrient, and binds into larger particles therefore it can be taken off through the pools filter medium. Lanthanum can be kept in the pools filter in large quanties without causing cloudy water.

To conclude, phosphate removal may be the secret to maintaining algae free, quality pool water, while allowing other chemicals to be effective inside their optimal level.

Additional algae insurance, may be the using a preventative, "long life" copper based algaecide to use along with regular testing for phosphate.

While phosphate will accumulate within a pool naturally, you will find steps pool owners usually takes to prevent excessive levels. - Don't allow runoff from gardens and lawns to go in the pool - Remove leaves in the pool regularly and promptly - Use a lanthanum compound phosphate remover regularly - Have the pools water tested by the professional.
