Balanced water protects your pool structure, tiles, and equipment, and keeps the water safe for swimming. Poor water chemistry can damage the pool, reduce equipment life, and cause skin or eye irritation.

The main things to test are chlorine level, pH, calcium hardness, alkalinity, and salt level (if you have a saltwater system). Each plays an important role in keeping water clean and safe.

We recommend testing at least once a week. If you have a saltwater system and your pool is used often, you may want to test every 2–3 days.

The ideal range is between 7.2 and 7.6. This keeps chlorine effective and protects both swimmers and pool surfaces.

If the pH is too high, add pH Minus. If it’s too low, add pH Plus. Always follow the manufacturer’s instructions and adjust gradually.

Use a pool water test kit or test strips. For a chlorine pool, add chlorine manually. For a saltwater pool, adjust the salt chlorinator’s output or the pump runtime.

Use a salt test meter or strips. Most salt systems work best between 3,000 and 4,500 ppm. If it’s low, add pool-grade salt.

Turn off the pump, set the filter valve to “Backwash,” and run the pump for 2–3 minutes until the sight glass water is clear. Then set to “Rinse” for 30 seconds before returning to “Filter.”

This applies only to saltwater swimming pools. Most salt cells are self-cleaning, but if you notice any scale buildup, it’s best to contact our technician for advice. In some cases, the cell may need to be removed and cleaned with a mild acid solution, but this should be done carefully to avoid damage.

We test and adjust pH, chlorine, calcium, and alkalinity; check and adjust the salt chlorinator; vacuum the pool; brush the walls and waterline; skim surface debris; backwash the sand filter or clean the cartridge; clean the pump basket; inspect and clean the chlorinator cell; and check the automatic refill system.

Keep the pool free from leaves and debris, run the pump daily for the recommended time, and check chlorine and pH weekly. If you see cloudiness or algae starting, contact us immediately so we can prevent bigger problems.

Most chemicals we use in the pool are safe to swim in immediately after they are added, as long as the water is circulating. The only exception is chlorine shock treatment — in that case, you should wait at least 8 hours or until chlorine levels return to normal.

Most pools need the pump to run 6–8 hours daily. In very hot weather or with heavy use, you may need to run it longer to keep water clean and clear.

Keep the water balanced, run the pump daily, brush the walls weekly, and don’t let chlorine levels drop. A monthly service program is the easiest way to avoid algae.

No, most cleaning is done with the water in place. We only drain a pool for major repairs, resurfacing, or if the water quality is beyond recovery.

First, check your chlorine and pH levels. Run the pump longer, clean the filter, and remove any debris from the pool. If the water doesn’t clear within 24–48 hours, contact us for service. We will arrive with the right chemicals to adjust the water balance and clear up the water. We will also advise you about the correct running time for your pump and filter, and if needed, check the condition of the sand inside your sand filter..

Yes, we handle all pool equipment repairs and replacements, from pumps and filters to chlorinators and timers.

Yes, in saltwater pools the pH level often rises over time. High pH makes chlorine less effective and can cause scale on tiles and equipment. During our service visits, we always check the pH and add the right amount of pH Minus to bring it back into the correct range.

Calcium hardness needs to be balanced. If it’s too low, it can make the water “hungry” and cause it to dissolve calcium from the pool surface, damaging tiles and grout. If it’s too high, it can cause scaling on tiles, pipes, and equipment. We check calcium levels on our service visits and adjust them by adding calcium increaser or by diluting the water if it’s too high.

Black algae is a stubborn form of algae that grows into cracks and grout lines. It’s hard to remove once established. We use a special preventative chemical during service visits to stop it from growing, especially in pools that have had black algae problems before.

Yes, water with high iron content can cause brown or rust-colored stains on tiles and surfaces, and can also lead to scaling inside pipes and equipment. We have special chemicals that bind to the iron and prevent it from causing damage.

A strong chlorine smell usually means the chlorine is “locked up” as chloramines from dirt, sweat, or sunscreen in the water. This is a sign the pool needs a shock treatment, not that too much chlorine is present.

Yes, heavy rain can dilute chemicals, lower chlorine, and change pH levels. After rain, it’s important to test the water and rebalance if needed.

Zelbrite, also known as zeolite, is a natural volcanic mineral used as premium filter media. Compared to standard sand, it offers much finer filtration, capturing particles as small as 3 microns (versus around 20 microns with sand), resulting in clearer water and fewer chemical adjustments

• Less backwashing needed — saves up to 50% water because of its higher dirt-holding capacity.

• Improves water quality — helps remove ammonia and chloramines, reducing odors and skin or eye irritation.

Many commercial facilities and swim schools choose Zelbrite to deliver top-quality water and reduce maintenance costs.

No special equipment is needed and no modifications are required. Zelbrite works in all standard sand filters. In fact, because of its superior filtration capabilities, you’ll typically backwash less often, extending the time between cleanings.

A variable speed pump can run at different speeds instead of just on or off. For normal daily circulation, it can run at a much lower speed, which uses far less electricity, and only run at high speed when needed for cleaning, backwashing, or special features. This can reduce your pool pump’s power use by up to 50–70%, which means big savings on your electricity bill. It also makes the pump quieter and can extend the life of both the pump and other pool equipment.

Yes, in many parts of Thailand, especially in rural areas, the electricity supply can have voltage drops or sudden spikes. These can damage pumps, chlorinators, and other pool equipment. To prevent this, we supply our pump room control boxes with built-in voltage protection. This helps protect your investment and keeps the system running safely even when the power supply is unstable.
