It's not the first time we've heard of someone learning to swim in a biological pool. But this time it was a whole swimming class. Last summer, several children aged 7 to 9 used a biological pool belonging to the parents of one of the children for swimming lessons with a teacher. This happened [...]
In natural swimming pools, biological processes are the same as those in big natural lakes. Aquatic plants play a crucial role in maintaining water quality. The topic of water treatment with aquatic plants was also on the agenda of the 17th Aquatic Plant Symposium in Lisbon, September 15-19, 2025. Therefore, we accepted the invitation [...]
Converting tanks into biological pools depends on several factors, such as size, depth, and other characteristics of the existing tank. For example, on a century-old farm in the north of the country, there was an old stone block tank. Its position, shape, and size allowed it to be incorporated into the design of a [...]
There are rootless aquatic plants living in clean waters called Utricularia. They are distributed worldwide, and two species also exist in Portugal. The plant's green structure is a very thin stem with leaves reduced to filaments. On these thin branches, we can find the utricles. These are round structures about a millimeter in diameter [...]
Everything is possible, nothing is mandatory – that's our viewpoint regarding the use of home automation in biological pools. There are many reasons to automate as much equipment as possible in a home, and biological pools are no exception. In a vacation home with a biological pool, for example, where no one is present [...]
We are not birds, but human beings. We don't have wings, but we invented drones. Normally, standing up, we observe the water of a biological pool from a side perspective. This is our usual view, the everyday perspective of the water mirror. With a drone, we can gain another perspective and see the beauty [...]
Our biological pool design business has spanned three decades, and over that time, many projects have emerged and continue to emerge. In addition to new construction, we also renovate older biological pools. Our construction team is frequently called upon to work on these older pools. Sometimes, these are minor improvements, such as renovating a [...]
This microscopic animal that cleans the water in biological pools, captured in the photo above, is a water flea, or rather, a cladoceran, a species of small freshwater crustacean. As the image demonstrates, its digestive system is full due to the bioactivity of this animal. This happens because the water flea feeds on microalgae [...]
The kingfisher is a bird many people know, but few have had the chance to see. In various wetland habitats—from streams and lake shores to biological pools—this multicolored bird can be spotted by those who know one of its most revealing habits: its distinctive call. The kingfisher has a habit of calling out while [...]
August is vacation month. Hot days! To cool off, everyone is looking for places by the sea. The seaside, the riverside. Or the biopoolside? Everyone has their own preferences. What matters is the presence of water, to take a dip and escape the heat, refresh body and soul, and rest in the cool water [...]
