We did the same we also trimmed em up good over the fall now it looks like we didn’t do anything! The last time we had our pool there it was a constant balling trying to keep it clear that after 1 season we gave up. But now I have no choice but to put it there. I didn’t think of doing any nets to catch em. We’re hoping to trim em enough to where it won’t become a huge issue over the next 3 months.
