The main objective in a pool Start-Up is to clear or get rid of the plaster scale (dust), and to balance and stabilize the water chemistry in the pool as soon as possible. The first 30 days of plaster curing are the most critical. The need for proper water chemistry and maintenance continues for the life of the pool. The following are some of the "do's and don'ts" for starting up a freshly plastered pool.
The Source of Water
Before adding any new water to the pool, make sure you know the quality of the water. This is recommended because water quality is not the same everywhere. You may find that your local source water is not suitable for filling a freshly plastered pool. It is recommended that all water chemistry reading be written down for future reference.
Determine The Water Gallonage Of Your Pool
You may want to take a meter reading if you are filling from one source with a water meter.
Filling The Pool
After the pool has been plastered, the plaster crew should leave a house in the pool to fill in with water. This hose should have a clean, soft cloth tied on the end of it to diffuse the water so that it does not whip, protects the pool surface from being marred be the end of the hose, and to catch any debris that may be in the water system. Do not add anything but portable water. Make sure the fill is not connected to a water softener.
Test The Water Again
You may find that the water is substantially different after filling the pool than when first tested. Write the chemistry needed for calcium, water must contain a minimum of 150 ppm of calcium. Insufficient amounts of calcium in the fill water fill force the water to draw calcium from the fresh plaster material, creating surface conditions which may not be able to be corrected.
Starting The Equipment
Due to the varying differences in source water chemistry, it is up to the person who is doing the Start-Up to evaluate the water conditions present. It must be perfectly clear that the person administering the chemicals should be aware of the power and effects of each chemical and the possible reactions of each chemical. It is the sole responsibility of that person to administer the chemicals in a calculated and safe manner.
Adding Stain Preventative And Water Clarifiers
These chemicals are extremely important. They help minimize normal staining. Do not add these chemicals until after the pool is filled.
Cleaning The Scale (Dust)
You may notice plaster scale (dust) on the bottom of the pool. This is normal and will go away with proper treatment and brushing. The main objective is Starting-Up a pool is to clear or get rid of scale (dust) and to balance water chemistry in the pool as quickly as possible.
Start-Up Do's and Don'ts are designed to provide basic new plaster Start-Up information. There are other Start-Up techniques and procedures available. Please consult with your plasterer, service technician or other pool professional.
