How to Avoid Scaling in a Plaster Salt Water Pool System

What You'll Need
Water testing kit
Soft water or tri-sodium phosphate
Scale inhibitors
Sodium bicarbonate
Muriatic acid
Sodium bisulfate
pH balancer
pH strips
Pool brush

Over a period of time, scale deposits in a salt water pool system become more and more apparent. One of the main reasons why there is a buildup of such scaling is due to the water imbalance inside the pool. Moreover, pH differences and the calcium content of the water are other contributors to this problem. These scale deposits become extremely difficult to remove, especially if a regular cleaning and maintenance pattern is not followed for your salt water pool. The section below will emphasize ways in which you can avoid such scaling in a plaster salt water pool system.

Step 1 – Take Necessary Precautions

It is best to keep in mind a small number of safety instructions since you shall be dealing with various chemicals when carrying out this activity. First, it is best to keep on hand a pair of rubber gloves and eye goggles. This will ensure that your skin and eyes are protected from the materials being utilized. Moreover, it is also advisable to wear a pair of old clothing when performing this task.

Step 2 – Use Water Testing Kit

One of the first steps in this regard is to conduct a water test of the pool. This will be done using a water testing kit, which is easily available from home maintenance or pool stores. Follow the instructions written on the kit and test the alkalinity level of the water. Ideally, it should be between 80 to 120 PPM. In the case that the alkalinity level turns out to be considerably higher than 120, add a small amount of sodium bisulfate or muriatic acid. On the other hand, if the alkalinity level is lower than 80, add in a small quantity of sodium bicarbonate. Make sure this step is carried out before testing the pH of the water in the plaster salt water pool.

Step 3 – Test pH Level of Water

Now, the next step is to ascertain the pH level of the water. This can easily be done by using a pH strip test. Follow the instructions on the pH strip and determine the pH level. Ideally, the pH of salt water pools should be around 7.2 to 7.6, meaning it should be a neutral pH level. However, if the level is either too high or low, adjust this by adding in a small amount of the pH balancer.

Step 4 – Add in Calcium Inhibitors or Soft Water

Given how scaling is also caused by high levels of calcium in the water, it is best to keep it in check as well. From time to time, add in small quantities of soft water or tri-sodium phosphate into the pool in order to keep the calcium levels balanced. Scale inhibitors available at home maintenance stores can also be utilized

Step 5 – Develop Regular Cleaning Schedule

Lastly, in order to avoid future scaling deposits building up in your pool it is advisable that you develop a regular cleaning schedule for your salt water pool. When carrying out such a cleaning, make use of pool brushes to clear off the scaling from the tiles and floor of the pool. However, do make sure you clean your pool regularly to avoid a buildup of scales.
