This guide is for those who are considering building a new pool or renovating their existing pool. We discuss the costs, benefits and possible downsides of various pool interior products that are available. So, if you are unsure of which surface would suit you best then this guide will be very helpful.

As with every other aspect of water chemistry, calcium hardness also needs to be in balance to protect your pool surface from calcium formation, stains, or corrosion. High or low calcium hardness can cause white staining on pool surfaces, etching, or discolouration.

Almost daily we receive calls from distressed clients saying the following – “I got some cheap salt from my local hardware store and now I’ve got these ugly brown stains all over my pool”.  Often, this brown staining becomes evident within hours of adding the salt to the pool.

Our technician visited a green pool last year that had five times the normal chlorine level and was still green! Why? The pH of the water was so high that the chlorine was prevented from working and so it was not able to clear the pool.

Poor pH balance causes nearly every type of stain that our technical team see each day. Our photo gallery shows some extreme cases where the pH has been left to drift a long way above the suggested level.
