Swimming pool cleaner/filter
I have an old (about 50 years) 50.000 liters (13 208.6026 US gallons) swimming poll that doesn't have any kind of cleaning or filtering machinery (if you know what I mean) so it's just like buried water tank :).
The problem is that it's often filled with grass, leaves and bugs that sink to the bottom of the pool and I don't know how to get rid of them.
I have a water pump that I use to empty the pool that takes about 2 liters/second that I'd like to use to "vacum" clean the pool floor but I don't really know how
Any ideias? thanks!
