Pool Stains

Stains on your pool plaster can greatly reduce the aesthetic of your pool. There are several chemicals available that claim to rid your pool of stains, however we find that these are generally used to prevent stains, especially in areas with high concentrations of metal in the water.

Here are a couple of links to products that are designed for stains.

Sequestering agents and or “stain out” are very commonly used right after the initial plaster job to aid in the balancing of the pool and protect the shell against staining.

These products are pretty pricey, as you can see these products can run from $15-$30 for 1 qt as a result they are mainly used when the pool is initially installed or plastered.

The prices for these products online are usually pretty competitive and sometimes better then retail and can be purchased and administered per the directions on the bottle. These chemicals can be purchased and administered, however in my experience I haven’t found them to do much once there is a stain. Once staining occurs the most effective solution in my experience is to perform an acid wash. You can spend all the money you like on a barrage of chemicals with no guarantee as to whether they will achieve the desired result. Over time you will inevitably need to acid wash and replaster due to the nature of chemicals coming into contact with pool equipment and plaster, and each pool is different with respect to this issue.

Here is a little more information on the above:

Sequestering agents. A sequestering agent is a chemical that combines with metal ions to help keep them in solution and prevent them from falling on the pool’s surface and leaving a stain, according to NSPI.
These products, which can also be used to control scale buildup, are used mostly for prevention. They won’t remove old, existing stains (that’s a job for a dedicated stain remover), but they will work on potential stains and keep them from becoming visible.
Source water can sometimes be rife with metals, so the use of a preventive sequestering agent is critical, say service professionals.
“In some of our rural areas, our customers have well water with naturally occurring metals,” says Suzanne Heim, marketing director at Classic Pool & Spa, a retailing/service company in Gladstone, Ore. “So we have to do a lot of metal control.”
Eastergard notes that metals often are a problem even if they’re not in the source water. For example, iron can find its way into a pool if there is a notable amount of construction in the area or if old pipes are being dug up for renovation. He points out that a sequestering agent will keep the staining at bay, which is important because iron can wreak havoc on a pool’s surface when certain chemicals are added to the water.
“If you get iron in your water and then shock it, it will turn the steps yellow-brown,” Eastergard says. “Then the customer thinks they’re dirty and you’re not cleaning the pool. This stuff just plates onto the shell material, and it can plate onto the plastic fittings.”

Swimming Pool Draining Procedure

Swimming Pool Draining Procedure
The storm drain system and sewer system are two completely separate drainage systems. The storm drain system flows directly to the Los Angeles River, which eventually discharges the water into Long Beach Harbor without any treatment. The sewer system takes all household wastewater from toilets, showers and sinks and routes it through your plumbing system into the Los Angeles-Glendale Water Reclamation Plant. Once there, it receives three levels of filtration treatment before being discharged into the Los Angeles River.

Therefore, the preferred method of draining your swimming pool is to the sewer system because the water will be treated before it is discharged into the Los Angeles River. Oftentimes, homes are equipped with a sewer clean-out which can be utilized for draining your pool.

If the sewer system is not accessible, then pool owners should dechlorinate their pool water by allowing the water to sit in the sun and not add any chlorine for 10 or more days and verify the following prior to being discharged to the street:
• The residual chlorine can not exceed 0.1 mg/L (ppm)
• The pH is between 6.5 & 8.5
• The water is free of any unusual coloration
• There is no discharge of filter media
• There is no discharge of acid cleaning waste
• Any pipe connection to the storm drain system has permits from the city or county having jurisdiction

Compliance with these guidelines can be verified using a pool testing kit. In addition, if time does not permit allowing the water to sit 10 days in the sunlight, you may purchase dechlorinating chemicals from local pool supply companies.
By ensuring compliance with these criteria, you will make a significant contribution toward keeping pollutants out of Los Angeles County’s creeks, streams and receiving waters and help to protect organisms that are sensitive to pool chemicals.

Foul Weather

During periods of foul weather (rainfall, strong winds, etc.) we are often forced to alter our normal maintenance procedures. While we do service your water system during these periods, we may not vacuum if we cannot see the bottom of the pool due to heavy rain or winds. We will not take the chance on clogging your plumbing or your equipment with unseen objects that may be at the bottom. Chemical and all other service functions will be performed to the extent that they are possible or necessary.

Once the Foul Weather has subsided we will clean up any resulting mess in your water system. In the instance of heavy amounts of debris, we will take the majority of the debris from the water with a device called a Leaf Bagger. This is a water-powered device that will remove leaves and debris from your system without clogging your plumbing. After this is done, there may still be a large amount of small debris suspended in the water. We will vacuum this up on our next scheduled visit (assuming that the debris has settled to the bottom).

It generally takes at least double the amount of chemicals as well as twice as much labor to clean up the mess resulting from Foul Weather conditions. Except for extreme cases we do not charge extra for this. If you are willing to have the mess cleaned up during our regular weekly trips, we are willing to do it as a part of your regular service. Customers who desire quicker clean up without additional expense should arm themselves with a Leaf Rake, Skimmer Net and Telescoping Pole. We can deliver these to you or you can pick them up at the nearest pool supply house.

At times you may need the pool cleaned up sooner that your next scheduled visit. For this situation, you may call us to schedule an Extra Service Day. It may take one, two, or three extra trips. All you have to do is call.

As always, if you have any questions or comments regarding scheduling, performance or other services we offer please feel free to call our service center at 213.999.7665. Saturday Sunday and evenings, you can leave a message on our voice mail and we will respond as soon as possible. We are dedicated to being your #1 pool service company!

Spa Draining

Periodic complete draining of spa water is the most important component of proper spa water maintenance. High bather loads and the hot water conditions cannot be handled over long periods of time without draining the spa. The following is a dumping formula that is a good guideline to go by.

First, divide your total spa gallons by 3. Divide this result by your Bather Load, which is the average number of bathers per day. The final result is the estimated number of days between water changes recommended for a properly maintained spa or hot tub.
Example,

Residential:

600 gallon spa / (Divided By) 3
___________________ = 100 Days

2 People per day bather load


Once you have determined how often your spa needs to be drained you may perform the draining on your own, or you can have LA Pool Guys perform this service for you at an additional cost. If you choose to drain your spa on your own you can purchase a sump pump at a local hardware store to speed up the draining process.
