Natural Chemistry Pool

Phosphates, nitrites and nitrates in pools. What are and what they do:

Phosphates and nitrogen are 2 natural elements in nature. Phosphorus is mineral and nitrogen is a gas. In nature, no cause or contribute to the problems of the pool. However, when they are "added" to the pool water, Problems can arise – especially in a situation of poorly maintained. The two most important problems are of moderate to severe algal blooms and demand chlorine. Both are essentially created as a buffet table for any algae just come, eat and thrive.

Phosphates tend to enter the pool of products lawn care, fertilizers, aerosols, etc. phosphates can also come from dead skin cells! (So, another good reason to shower before entering the pool.) These lawn care products can be brought to people walking on recently treated areas where they are literally walking in the pool. They can also "drift" in when sprayed or simply because of a windy day. Remember, phosphates, may come from your yard, garden your neighbor or even someone who does not even know who lives 3 blocks away. Phosphates (or forms of phosphorus) were added directly in the pools (yes!) In the form of "remove metal 'and' control slick" chemicals – all pool kidnapping or products containing phosphorus binders.

Nitrogen also can enter the pool of products for lawn care, but more typical is a case of sweat (shower before using the pool) of urine (use the facilities before going to the pool) or other types of ammonia (ammonia is composed of nitrogen and hydrogen – NH4). If your local water supplier uses chloramines to disinfect water after large amounts of ammonia and nitrogen are therefore entering the water. Algae loves both nitrogen and phosphates (phosphorus).

Here is the typical situation with nitrogen. Nitrogen enters the water and combines with oxygen to form nitrite (NO2). Nitrogen normally have the oxygen of HOCl (hypochlorous acid – the form of chlorine that kills bacteria and algae), resulting in chlorine demand. You will have a difficult time maintaining chlorine, algae grow, the water will become cloudy, etc. Once you have taken nitrites and nitrates become more oxygen (NO3), which are there to stay. The only way to remove nitrates from water is to drain and refill with fresh water hopefully not contaminated with nitrites. Contribute to a powerful oxidizing some degree. Nitrate (NO3) can live with, Nitrites (NO or NO2) are causing the problem.

With phosphates, nitrites or nitrates, as long as a good, remains solid and the level of chlorine, bromine, is not usually a problem. However, when chlorine is stressed due to high bather loads, parties, storms, etc, or if there is a problem of demand for chlorine, phosphates and nitrates only feed right into any of those present and the algae problem worsens significantly.

In performing side by side in order to prove the importance of phosphate in pool water in pools treated the same (time of execution of the filter, chlorine in the skimmer, algaecide every week after the initial dose, weekly pool surprised to oxidize organic waste, the water balance of good quality), there was no difference (phosphates were almost irrelevent in the case of pool water problems) in water quality and clarity among the control group and that adding the pool phosphate made regular water (as fertilizer). Conclusion: follow the 4 steps of the good chemistry of pool water: 1. maintain a constant level of disinfectant (chlorine, bromine, biguanide, etc), 2. Clash of the pool week to oxidize organic waste and the environment 3. Add weekly algaecide to prevent algae growth, 4. Maintaining adequate levels of pH, total alkalinity, calcium hardness.

Addressing the problem:

1. Maintaining the balance of good quality water – PH of 7.4 to 7.6, total alkalinity 125 to 150 ppm, calcium hardness 200 to 250 ppm.

2. Maintain good residual chlorine or bromine in the water.

3. Shock Pool (BioGuard Burn Out Extreme ® Smart Shock ® & Oxysheen ® – especially bromine – are good products) and add algaecide (BioGuard ® Back Up ®, Algae All 60 ®) per week.

4. Get a chlorine demand test done twice per season. If there is demand for chlorine, to treat thoroughly and aggressively.

5. Make sure that the swimmers and swimmers shower before using the pool.

6. If you know or suspect that phosphates have been introduced into the pool, Chemistry PhosFree ® Natural ® is a great product that removes phosphates from pool water, thus depriving the algae of a major food source. Some customers how to use this product for "peace of mind".
