Generally speaking algae in the pool is a result of inadequate levels of
sanitizer (chlorine) in the water that is needed to kill the bacteria. We take great
pride in keeping your pool "algae free" at all times by keeping a safe and
effective sanitary environment in the pool.
Essentially there are three types of algae:
1) Green algae - A slimy film which common shows when pool hasn't been sanitized
2) Yellow and mustard algae - A yellow slimy film which occurs when sanitizer level is
low and pool has poor circulation problems.
*Mustard algae can and will occur even
with proper sanitation levels if poor circulation and filtration problems are
3) Black algae - Small black spots which can and will root into walls of pool. It
is by far the worst of the three types and very difficult to remove.
