As we say, it is better to prevent than to cure. You need to keep your swimming pool or hot tub clean for a safe bathe.

For that, you would need to test your water at least 3 times a week. You will not only have a better control on your pool but you will also use less water treatment. 

Leaf Skimming

Leaf skimming removes debris before it sinks to the bottom of your pool. Debris becomes much more difficult to remove and can also cause staining if it reaches the bottom of the pool.

Use a long-handled leaf skimmer to remove leaves, insects, and any other debris floating on the pool surface.

Vacuuming

A weekly vacuuming is essential for keeping your pool consistently clean and maintaining sparkling clear pool water.

Vacuuming removes debris from the pool floor as particles that are left at the bottom of the pool can cause staining. If your vacuum attaches to the skimmer or to a designated vacuum point, be sure not to allow any air into the hose. In order to do this, submerge the vacuum head and hose underwater before connecting it.

Brushing

Regular brushing of pool walls and bottom prevents the unwanted build up of dirt, dust, leaves and dead insects. This debris can cause stains on your pool surface.

You should use a brush to remove loose dirt, dust and soil that has collected on the sides and bottom of your pool. Direct the collected dirt to the main drain so that it can be caught by recirculating currents or easily vacuumed. If your pool does not have a main drain, you should vacuum immediately after brushing. Concrete pools require a stiffer bristle than vinyl-lined pools.

Cleaning Tide Marks

Cleaning oily deposits along the water line (often due to the use of sun screen or body lotions) not only improves the appearance of the pool, but perhaps more importantly removes potential breeding sites for micro-organisms. 

Finally, you should change your sands in you swimming pool at least every 3 or 4 years.

Your chlorine or bromine should be around 2 ppm or 3 ppm and you should have a 7,2 ph. All this in order to have an optimum bathing comfort and sustainability of your pumps and heaters.
