There are many masterminds and ingenious scientists. But the best inventions are created by nature. If – befitting of today’s Day of the Watermelon – I take a look at the red fruit then the thick skin is directly apparent.It ensures that the melon remains beautifully succulent and well protected on the inside. It is precisely this function that the grando roller cover performs, protecting the pool water from dirt and significantly reducing evaporation. In contrast to the summer fruit, the “pool skin” is in season all year round. And as clever as they are, Russian people transform the watermelon into an all season fruit by using watermelon juice for making liquid. So the “intelligent” fruit can be enjoyed even in winter – when grando will be present at the aqua-therm in Moscow from 2 to 5 February 2016. Save the date. We are looking forward to welcome you on our stand inside the German Pavillon.
