Unfortunately, an open pool is a magnet for whatever is in the air -
leaves, dirt, bugs, you name it.
If it's in the air, it can end up in your pool. Unless
of course you have a Coverstar automatic pool
cover.
Like a lid on a jar, the cover keeps out
most of the bad stuff that can make pool
ownership less than enjoyable.
Because the pool is typically covered
except when in use, the evaporation
of water and pool chemicals is
dramatically reduced. That means you
need to test and replace pool
chemicals much less often.
