Water Care & Treatment

PROXIM s.r.o. has been focusing on water treatment methods for many years and so the company decided to set up a project that would be unmatched in its scope and content and provide useful advice through Mr. Clearwater, an expert in swimming pool and garden pond water care and treatment.

Few professionals can claim they are the only true and experienced experts who have an answer to every question. We are no exception and the more in-depth knowledge we obtain, the more we feel that we know much less than in the beginning. Nevertheless, putting to use our knowledge and experience, we ventured into creating space with tips and advice on how to maintain water in garden or public swimming pools, whirlpools or wellness pools, and decorative or swimming ponds.

We hope that all users will find what they need and what interests them along with useful tips for easier maintenance of their swimming pools, whirlpool baths or ponds. If not, we welcome any comments or suggestions regarding the content or the form of the website that will help us improve it continuously. Accept the invitation of our expert and guide, Mr. Clearwater, who is ready to help solve your problems. More info at www.peceovodu.cz

What can happen if the water pH is too low?

A pH value below 6.8 causes metal and concrete corrosion, discolouration, as well as eye and skin irritation.

What should be done after filling the pool with water for the first time?
First of all, you should measure the pool water pH with a pH tester. The optimum pH value is between 6.8 and 7.6. If the measured value is higher, lower it by adding the product pH MINUS, or if it is lower, increase it by adding pH PLUS.
Measure the water hardness value, especially if you use local water sources to fill the pool. If the water is too hard, use the HARDNESS STABILIZER. This will protect the pool walls and bottom from deposits of minerals, the removal of which is a tedious task.
The next step is to chlorinate the water by adding the CHLORINE START quick dissolving chlorine granules. The dosage is 40–80 g per 10 m³ of water in the pool. This way, the initial chlorine concentration in the water should be adjusted to 0.3 – 0.5 mg/l. After start-up chlorination, preferably use COMBI or MULTI tablets to sanitize and treat the water.

How can I measure the pH value of the water in my pool?
There are many ways to measure pool water pH. Tablet mini testers are most widely used. Alternatively, the pH can be reliably and readily measured with a drop test kit.
Electronic pH meters are also available but rather expensive. The use of universal pH test strips is not recommended because you can only estimate whole pH units with them, while you need to know the pH to tenths of units.

How to prepare the pool for the swimming season | Mr. Clearwater | 25 April 2013
What you usually see when you first remove the winter cover at the beginning of the season doesn’t look as bad as you were afraid of seeing. The water is somewhat turbid and green and there is some dirt on the bottom and some stains on the walls above the water line. Great! Stains can be easily removed with our GEL CLEANER, and after rinsing everything off thoroughly, you can collect the dirt from the bottom with a leaf skimmer. Now you are ready to fill up and filter the pool. Careful preparation of the pool for winter has paid off because properly treating the water and covering the pool have made the new start of your pool much easier. There is no need to contend with tough layers of lime scale, proliferous aquatic life or stubborn stains or dirt. Now is the right time to employ pool chemicals, which are simply indispensable. The key to success is to adjust and maintain the correct pH value of the water. If it does not lie between 6.8 and 7.6, the efficiency of other water treatment products rapidly decreases along with the water quality. Measure the pH with an appropriate tester and adjust the pH level with pH PLUS or pH MINUS by following the instructions for use. Before sanitizing the water, it is advisable to determine the water hardness and to adjust it with HARDNESS STABILIZER.
