FREQUENTLY ASKED QUESTIONS

Several customers erroneously believe that a pool opening contract includes the complete cleaning of the pool, and many companies take advantage of that gullibility. Indeed, although the price of a simple opening may seem appealing at first, most customers find themselves with a functional pool after its opening, but a completely dirty pool. Also, most pool companies sell a large quantity of chemical products and offer only a few summary explanations on how to use these products. Often, you will have paid more for chemical products and will have spent more time trying to clean the pool than if you had used the services of our specialists for the spring cleaning. Although the initial fee is substantially higher, resorting to H2prO Pool Maintenance specialists to open AND spring clean your pool provides you with a clear and clean one once the job is done, and this regardless of the time needed to do the cleaning. Also, you won’t waste money on unnecessary chemical products, and your water will be perfectly calibrated for the beginning of the season. Finally, resorting to these two combined services entitles you to a rebate on the individual price of each!
This type of comment, that we hear very frequently, is partially true. Indeed, having a salt disinfecting system for the pool alleviates the required daily maintenance. You just need to put the necessary amount of bags of salt when starting the pool and add some during the season because of the evaporation, and you’re ready to use it. However, disinfecting with salt does not prevent the neighbouring dirt to fall in the pool, and does not clean the black lines on the edge of the liners. Also, as for all types of swimming water, it is of the utmost importance to do physicochemical tests at the beginning and in the middle of the season to maximize disinfection. Finally, although they require less handling of disinfectant than standard chlorine pools, pools with salt systems also need cleaning and verification of daily chemical parameters!
Chez H2prO, nous souhaitons que chaque client puisse bénéficier d’une piscine impeccable en tout temps. C’est pourquoi nous accueillons l’arrivée des robots nettoyeurs de parois et de fonds avec joie. Nous croyons que ces accessoires de plus en plus abordables sont un excellent complément à nos services. Il faut comprendre qu’un robot nettoyeur, bien que très pratique pour un nettoyage de fond complet, nécessite plusieurs manipulations de la part de son propriétaire. De manière générale les robots s’arrêtent et doivent être vidés et nettoyés après un cycle de nettoyage allant de trois à cinq heures. Certains modèles vont sur les côtés de la piscine en plus de nettoyer le fond, mais aucun n’effectue de tests d’eau ni ne s’assure que tout ait été nettoyé parfaitement. Plusieurs de nos clients possèdent un robot nettoyeur et lors de nos visites de nettoyages de la piscine et de tests d’eau, nous nous occupons de manipuler le robot, de le vider et de le mettre à l’eau.
First, to make sure you have clear water on a permanent basis, the first thing to do is to precisely calibrate the water chemical parameters at the start of the season. The main reason for troubled water problems lies in the fact that the unstable pH of water prevents the disinfectant to function correctly. To stabilize the pH, the water level of alkalinity must be maintained between 80 and 120 ppm and the calcium hardness between 180 and 220 ppm. Once these levels are reached, the pH should remain stable, and your chlorination will be able to fully disinfect your pool water. If all your chemical parameters are at the correct level and you continue to have troubled water problems, your salt system cell may be at the end of its useful life, or the salt in your filter needs to be changed. Don’t hesitate to contact us by email or by phone if you are having recurring problems with your water or problems for which you can’t find any solution!
These days, several alternatives are offered to replace the traditional granular chlorine as a disinfectant for residential or semi-private pools. The most popular is, undoubtedly, the salt disinfection method. The vast majority of structures for new pool constructions are designed to receive salt water. However, if your pool was built several years ago, switching from chlorine disinfection to salt disinfection may cause many corrosion problems and it is not the ideal alternative to eliminate tedious granular chlorine. The solution, as in the previous case, is to choose chlorine pucks that you put in a chlorinator, in the skimmer or in a floater that you put on the surface of the water. This method makes it possible to avoid having to put chlorine every day and ensures an efficient disinfection of the pool water. Finally, the alternative that we prefer at H2Pro Pool Maintenance is to use chlorine capsules. This type of chlorine is less messy and disintegrates more slowly than chlorine pucks. The majority of our customers have noticed a significant difference in the quality of their water when we started using chlorine capsules. But be careful, you must absolutely use quality chlorine to ensure its efficiency!
The formation of powders or sediments at the bottom of the pool is, most of the time, the result of poor quality products (very often chlorine products). Indeed, the reason why some brands of chlorine are cheaper than others is that there is a combination of bad quality products to chlorine. Plaster or chalk may be present in small quantity in some cheaper chlorine containers, and these elements do not dissolve perfectly in water, which causes the formation of a whitish powder at the bottom of the pool. The ideal solution to eliminate this type of sediment is to change the type of chlorine you use. However, we are aware that the price may sometimes be very attractive and that the use of a lower quality chlorine is appropriate for some types of pools, mainly smaller pools. In addition, the powder may also be caused by the proximity of a highway, renovations being done close to the pool or construction in the neighbourhood. Thus, to get rid of this fine powder that goes through the filtration sand, you have to use a bottom broom by putting the filter head on waste or drain position, depending on the brand. This way, everything that will be vacuumed will automatically be rejected on the street through the waste pipe of the pool!
Residential and commercial pools in Québec are mostly filtered through two distinct methods: sand filtration and cartridge filtration. Here are the differences between these two systems.

The most common filtration method is without a doubt sand filtration. It filters water at a fine level of 20 to 40 microns and has many benefits, in particular price-quality ratio, quick cleaning (backwash) and easiness to use. However, some disadvantages are linked to this type of filtration, including the duration of installation time, the higher price than a cartridge filter, the average quality of the filtration (may require the use of products to thicken the sand) and the over-consumption of water for each cleaning.

The other favoured filtration method by pool owners is the cartridge method. Its filtration fineness is established between 10 and 40 microns. That is why this method is favoured for small water-filled pools like spas. Its advantages include easy installation, a more reasonable cost at purchase, the good filtration quality and low water consumption. However, the disadvantages of this system are that you have to regularly clean the cartridge and the high price of these cartridges when you have to change them. Also, when the filter is very dirty, the internal pressure rises (it should always be between 15 and 30 psi), the circulation is inadequate and there is a danger of the pump overheating.

In the end, before choosing the type of filtration for your pool, be sure to have all the necessary information, and don’t hesitate to contact us for advice on the best system to choose.
