With a view to the fact that PROXIM s.r.o. has been focusing on water treatment methods for many years, it decided to create a project that would be matchless in its scope and content and provide useful advice by means of Mr. Clearwater, an expert on swimming pool and garden pond water care and treatment.

Only a few professionals would claim to be 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 pool, whirlpool or pond. If not, we welcome any comments or suggestions regarding the content or the form of the website that will help us improve it on a continuous basis. 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 to do after filling up the pool for the first time?
First of all, you should measure the pH value of the water in the pool with the aid of a pH tester. The optimum pH value is between 6.8 and 7.6. If the measured value is higher, lower it by adding pH MINUS, or if it is lower, increase it by adding pH PLUS.
Especially in cases when you use local water sources to fill the pool, you should determine the water hardness. If the water is too hard, apply the HARDNESS STABILISER. This will prevent the deposit of minerals on the pool walls and bottom that are difficult to remove.
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. This way, the initial chlorine concentration in the water should be adjusted to 0.3 – 0.5 mg/l. After start-up chlorination, you should use KOMBI or MULTI tablets to disinfect and treat the water.
 
How can I check the pH value of the water in my pool?
There are many ways to measure the pH value of water in the pool. The most widely used are tablet mini testers. Another reliable and easy way to measure pH are drop test kits.
Electronic pH meters are also available, but they are rather expensive. The use of universal pH test strips is not recommended, because the measured values shown on the pH scale are whole units, while we need to measure the pH value in tenths of units.
 
How to Get Your Pool Ready in Spring| Mr. Clearwater|25 April 2013
When you first remove the winter cover at the beginning of the season what you usually see underneath doesn't look so bad. The water is somewhat clouded and green and there is some dirt on the bottom and some stains on the walls above the water line. Great! Stains are easily removed with the GEL CLEANER and after rinsing everything off thoroughly, you can collect the dirt from the bottom with a leaf skimmer. Now you're ready to fill up and filter the pool. Careful preparation of the pool for winter has really paid off, because the properly treated water and covering the pool have made the start-up of your pool much easier. There is no need to contend with tough layers of lime scale, proliferous aquatic life, and 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 is not in the range from 6.8 to 7.6, the efficiency of other water treatment products rapidly decreases along with the water quality. The pH level is measured with suitable testers and it is adjusted with pH PLUS or pH MINUS products according to the provided usage instructions. Before you disinfect the water, it is advisable to determine the water hardness and to adjust it with the aid of the HARDNESS STABILISER.
