How Can I Clear Up Cloudy Water?

By testing and correcting the above causes of cloudy water, the cloudy pool water problem should disappear. Always use the proper Taylor test kit or test strips from Taylor Technologies to be assured of proper chemistry readings.


What Is Algae?

Algae are unsightly plant life that comes in a myriad of species and colors. They are by far the most common irritants of swimming pool owners. Algae can facilitate bacterial growth and therefore it is necessary to treat for algae long before it become visible and definitely when it becomes visible. All algae will make a high demand on chlorine. It will cost mush more in chlorine dollars with algae than without. The prevention of algae is one reason pool service professionals are so adamant about keeping your filters clean.


Why Is My Pool Green?

Most likely a lack of FAC Free Available Chlorine and or Algae or a combination of both. If the pool has been low or absent of chlorine for some time there is a good chance the green color is coming from algae. The object is to prevent algae blooms (visible algae). The more algae is visible in your swimming pool water the more green or cloudy the water. Proper water chemistry can help prevent a green pool and prevention is certainly more desirable than treatment. A proper level of chlorine and properly balancing all other aspects of your swimming pool water chemistry is a great algae deterrent.


How Do I Eliminate Green Algae?

Check your filtration system to make sure your filter is operating properly. If your filter pressure is too high, and your filter needs to be cleaned, call a pool service professional. Many injuries and deaths have occurred from filter cleaning. Filters are under pressure and even some professionals have been injured and killed from exploding filter lids. Your health and your life are more important than a few dollars. Always use a pool service professional for pool service and repairs.

After determining and correcting the issue that caused the algae bloom you will need to Shock your swimming pool water. Shock is highly concentrated dry chlorine. Most pool service professionals recommend an algaecice to treat green algae. Always follow the directions on the container if you do not have a pool service professional.

Why Do I Have Yellow Algae?

Yellow algae or mustard algae is usually cause by poor filtration or improper water chemistry. (See “Why is my Water Cloudy”) If you cannot determine the cause of the algae bloom, after the proper tests are performed, contact a pool service professional or take a sample of your swimming pool water to your local pool supply store that have a professional water testing department.


What Is Yellow Algae?

Yellow algae, or mustard algae as it is called by some pool service professionals, are again plant life. They can be resistant to large doses of chlorine and therefore must be treated immediately upon a bloom. Brushing the yellow areas with a pool brush before treatment is necessary for the chlorine shock to be effective. Yellow algae is easily brushed away but can return quickly if not treated immediately.


How Do I Get Rid Of Yellow Algae?

Brush the yellow areas vigorously and add an algaecide to you swimming pool water. Always read and follow the directions on the container.


What Is Black Algae?

Black algae spots occur in a swimming pool when your water has a low free chlorine level and/or the pool chemicals are unbalanced along with debris sitting in one spot to long or not be vacuumed enough. Good circulation is a must! The time it takes to avoid black algae is well worth your time and energy. Once you have a Black Algae, you must continue to treat it as black algae is a spore and continues to grow and must be continually treated and kept under control. Prevention, especially for Black Algae is a must.


How Do I Get Rid Of Black Algae?

Black Algae appears to have slime or shells covering the algae and protecting it from the effects of chlorine and algaecides. The shells must be cracked and the slime must be brushed vigorously before applying Trichlor. Always follow the directions on all containers of chemicals. The best course of action is to avoid black algae. A pool service professional should be able to eliminate the possibility of a black algae bloom by proper water chemistry and proper water filtration. Black algae can spread from other pools.


Why Does My Water Smell And My Eyes Burn?

Most likely you have Chloramines in the water. Chloramines are a combination of Chlorine and ammonia in the water. Chlormaines can be check by a standard chlorine test kit. There is typically two ways to check Chlorine levels. The most often is the free available chlorine in the water and the second method is the Total Combined Chlorine, which checks for Chloramines. They way to eliminate chloramines is to actually raise the chlorine level according to the test kit directions and basically oxidize/burn out the chloramines from the water.


How Do I Get Rid Of The Smell?

You must super chlorinate your swimming pool water. Whenever your water smells like chlorine and your eyes burn, add more chlorine. For the proper amount to add, contact your pool service professional or take a sample of your pool water to your local pool supply store with a professional water testing department. The rule is: when your eyes burn and your water smells, Chloramines are present!


Where Should My Water Level Be?

For optimum filtration your water level should be maintained in the middle of your skimmer opening.(See automatic water fill devices)


Why Am I Losing Water?

Water loss is a natural phenomenon for swimming pool owners. The loss of ½ inch and in some areas as much as one inch during the warmer months can be expected. However, if you are losing more than the fairly normal ½ to one inch per day during the warmer months, and if you continue to lose this amount during the colder months, you could possibly have a leak. To determine if you have a leak, you can perform this simple test. Fill a 5 gallon bucket with water. Mark the level of the bucket. Now mark the level of the pool at the tile level, tape can be used etc. Keep the bucket on the first step of the pool so its sits in the water so the bucket is the same temperature as the pool water. Let the pool circulate and do what it typically does in the normal 24 hours. After the 24 hours measure both the bucket and the pool from the level it was 24 hours prior. They both should have lost the same amount in inches. If the pool lost more than the bucket then you know you have a leak and a leak detection should be performed by a professional.


How Does Leak Detection Work?

Leak detection companies use sonar to detect leaks and their locations. The cost is minimal compared to the expense of digging up different areas of your pool area to discover if a leak exists or to find the location of the leak.


Why Is Finding A Leak Important?

A leak no only raises your water bill and increases your chemical costs, but in some cases a leak can undermine the very structure of your pool and/or pool deck. At the very least a leak can cause cracks in many pool decks.


Where Can I Find A Leak Detection Company?

Contact your pool service professional for a recommendation or check the Yellow Pages or on line for the nearest leak detection company.


Why Does My Plaster Have Stains?

Some minor discoloration is normal in new plaster as plaster is a natural product and has natural marbling that occurs. However, actual staining can be caused by the following:

Stains can also be caused by debris left in the pool. Usually metals escaping from this debris deposits itself onto the pool plaster and creates a discoloring. Items such as a leaf from a tree, if left long enough on the pool floor, can stain your plaster.


How Do I Eliminate Plaster Stains?

Stain removers and acid washing are two examples of how to remove plaster stains. However, a pool service professional should be consulted before any stain removal is attempted. The use of a stain remover and/or an acid washing should always be performed by a pool service professional. The damage that can be done to your pool surface (plaster) by stain removers and acid washing is far more costly than the cost of a pool service professional.


Why Is My Plaster Rough?

Rough plaster or sharp areas in your pool that can hurt your feet can be caused by poor water chemistry. Poor water chemistry can cause etching or pitting and both can be unsightly and irritating to swimmers. Etching, scaling or plaster roughness can be cause by low pH or alkalinity. Either way, we are back to water chemistry


How Do I Stop Getting Rough Plaster?

Make sure your water chemistry is balanced at least weekly. While this will go a long way in helping to eliminate rough plaster, it may not be enough. Sometimes rough plaster is a by-product of a poor plaster job and the roughness eventually works its way out from the gunite to the exterior of the plaster.

Why Do I Have Little Rust Stains On My Plaster?

Rust stains are typically caused from a foreign object that sat on the surface of the plaster. Rust stains can be from a cast iron header of a heater or internal part that is rusting. Rust can also be from rebar beginning to leach through the unite and plaster. Typical topical rust stains can be easily removed by a light sand or wire brush, rebar stains will have to be handled by a professional and determined what caused the rebar to bleed or leach through the plaster.
