How do you test for nitrates and phosphates in water?
For phosphates you can use molybdate solution but be careful it contains sulfuric acid.
Do phosphates lower chlorine in pools?
Phospates do not reduce chlorine. Ortho-phosphates become algae food and should be removed. The best amount of phosphates in a pool is zero. Below 200 ppb is acceptable. Phosphates above that level can contribute to algae blooms when chlorine levels fall, it rains heavily or water becomes unbalanced. Pool & Spa
What happens if there is too many nitrates and phosphates in water?
When there is too much phosphate in the water it causes algal blooms. When the decomposers try to break down the phosphate they use up all the oxygen, leaving none for the other organisms. when this happens all the organisms end up dying.
What are nitrates and how do they get into your water supply?
Nitrates are a major part offertilizers, so when we use fertilizers they get in the soil and from there to the underground water supply.The reason they usually get past the purification at the water plant is that nitrates are very soluble in water and very hard to separate
How do you raise phosphate levels in a pool?
You don't normally want to raise phosphate levels in your water. Phosphates are food for algae. You want to keep the phosphate below 125ppm to help prevent algae from growing in your pool. GO TO JACKS MAGIC WEBSITE AND READ DR. NEIL LOWRY'S PAPER ON PHOSPHATES. YOU WILL KNOW ALL YOU NEED TO KNOW.
What can you do about eutrophication?
Try to stop phosphates and nitrates entering the water
How do you test for nitrates and phosphates in water?

What happens to water systems when nitrates and phosphates increase?
Plant and algae growth increases
Can you swim with high levels of phosphates?
In a word, Yes. Phosphates are really a non issue. Phosphates are an algae food but IF YOU ARE MAINTAINING PROPER FREE CHLORINE LEVELS for the CYA level in your pool they are a non issue and you will not get algae. Phosphates are also often not the limiting factor in algae growth. Nitrates are also algae food and the only way to remove nitrates from pool water is by water change. There is not a nitrate remover that a pool store can sell you so nitrates are not normally tested. Phosphate removers have become big business and big profits for pool stores and chemical distributors but they are an entirely unnecessary product 99% of the time if proper pool maintenance is followed. High phosphate water is perfectly safe to swim in.
How do phosphates affect oxygen levels in water?
By eating chickens
What is considered to be the safe levels for nitrates in drinking water?
10mg/L
What has the author David C Reutter written?

Reutter has written: 'Nitrogen and phosphorus in streams of the Great Miami River Basin, Ohio, 1998-2000' -- subject(s): Environmental aspects of Fertilizers, Environmental aspects of Nitrates, Environmental aspects of Phosphates, Fertilizers, Nitrates, Nutrient pollution of water, Phosphates, Pollution, Water
What causes scientists to be concerned about the quality of lake water?
High levels of nitrates.
What products can make plants grow better?
Nitrogen,Potassium,Phosphorus (sulphates, nitrates,phosphates as fertilizers plus humus and water in a clayey/alluvial soil.)
What happens when there are too many nitrates and phosphates in a pond?
Nitrates and phosphates are fertilizers, and therefore if you have too much of them in a pond, it will become choked with an excessive growth of algae.
Why would algae come back two days after it was all cleaned off if there is enough chlorine in the pool?
You should get the pool water tested for 'phosphates' and 'nitrates', both of which can encourage algae. Common problem these days. Easy to get rid of if too high (phosphates max. 125ppb, nitrates max. 25ppm). E-mail me if you need more help.
How do lakes become eutrophic?
Eutrophication Eutrophication is usually the result of fertilisers being washed into a body of water e.g. lake or river. 1) farmers add fertilisers (containing nitrates and Phosphates) to their crops to help them grow. 2)Heavy rain washes the fertilisers off and the nitrates and phosphates dissolve. 3) The nitrates and phosphates that aren't taken up by plants are washed into a stream or river. 4)The high concentrations of phosphates and nitrates encourage rapid plant and algae growth. 5) surface plants (in the body of water) block sunlight. so plants in the water can't photosynthesize and die (so no more oxygen is being made through photosynthesis.) 6) the decomposing bacteria that break down the dead plants thrive (because of all the dead plants) and use up more oxygen. 7) oxygen concentrations in the water decreases and animals (e.g. fish) die due to lack of oxygen.
