My idea was that I can close off the pool "hermetically" with such plans, then can not attract insects or other invertebrates, as well as leaves, bird droppings and plant parts get into the pool.
This works so not because the next time it rains, so much water would collect in the tarp that you no longer get this down from the pool. Therefore, the plane has a number, about 1 cm wide holes through which rainwater can flow into the pool. It takes a bit of dirt that can not prevent anyway. This is so because the circulation pump.
Especially for us, it was very often the problem is that any animals in the pool were dead flies, etc.
Although some water floating on the tarpaulin, now significantly fewer animals get lost in the pool.
Unfortunately it happens häufier that the water but can not flow into the pool, but nevertheless in a few cm thickness is on the Plane. When bring down the curtain so the Plane falls into the water, surface water sämtliches mixes with the halfway clean pool.
Maybe it's me, but it's not as easy as it looks, so the pool cover so that it was even after Abmachen the film a lasting impact.
