Costa Rica Pools & ConstructionPool Care Basics

Caring for your Pool

By Glen Bain


Adequate filtration is essential. The water passes through the filter, is cleaned and returns to the pool. The correct size of pump and filter is critical. The sand in the filter (if applicable) will need to be changed every 2 years although this time period may vary depending on the factors affecting your pool. Please contact Costa Rica Pools if you are unsure as we will also be able to assist with this process.


Water moves through your swimming pool, distributing chemicals in the water. The aim flow(s) should be aimed 30-45 degrees down. This will give you better chemical distribution and the water flow will not affect the performance of the pool cleaner.

Clean the pump, filter and skimmer baskets weekly (more often if it is windy and there are trees or sandy areas around your pool). The filter must be ‘backwashed’ for 2-4 minutes and ‘rinsed’ for 1 minute weekly. If you are using a non self cleaning Salt Chlorinator, clean the Chlorinator cell weekly. Also, clean the surface of the pool with the pool skim net when required.

Testing the Water

Test the water on a weekly basis and maintain the following levels:

Chlorine 1 -4 ppm.
pH 7.4 -7.6 (ranges may vary depending on pool surface). Have the water analyzed at Costa Rica Pools once a month. We provide free water test for our customers; this will save you time and money in the long run.

Adding Pool Chemicals

Always add the correct chemicals in the correct quantities for safe, sparkling and algae-free water. When dissolving chemicals, NEVER add water to chemicals only add chemicals to water and DO NOT use a metal bucket when dissolving pool or spa chemicals.
