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.”

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.
