are only three things that will clear up a green pool:
Your filter system, your pool chemicals and you !
Unfortunately, there is no magic way to turn a green or black pool
clear overnight ! It usually takes a lot of time, effort and money to
clear up a typical "swampy" green pool. It is certainly best
if you never let your pool water get this dirty, however most pool owners
experience a "green pool problem" from time to time.
Although it is not easy work, there is a proven method of clearing
up a green, black or very dirty pool in the shortest time possible.
Follow the instructions below for the best results.
- Remove most of the large debris from the pool floor with a large
leaf net (not a hand skimmer!). This will stir up the water, and may
make your pool look much worse temporarily, but the stirred up debris
will settle within a few hours. DO NOT ATTEMPT TO VACUUM THE POOL
IF YOU CANNOT SEE THE BOTTOM OF IT OR IF YOU HAVE A LOT OF DEBRIS
ON THE BOTTOM. YOU MAY CLOG YOUR SKIMMER, FILTER OR UNDERGROUND PIPES
- Adjust the pH and Alkalinity levels of the water using pH Plus,
pH Minus and Alkalinity Plus. These levels must be within the proper
ranges or the water will never clear.
- Shock the pool. This means super chlorinating the water to kill
off any bacteria and algae. If your pool is very dirty, it may need
MANY gallons of liquid chlorine (shock) over a period of days before
the water clears. Start off by adding 3 or 4 gallons, and if you see
no results overnight, add 3 or 4 more gallons the next day. Continue
this process until you notice the water changing color to either cloudy
white, light green or clear. YOU CANNOT OVER SHOCK A POOL ! The more
you add, the quicker it will clear ! Note...shock is available in
liquid or powdered form, but we recommend using liquid (it works faster).
You may also want to add a high quality algaecide to the water at
- Run your filter 24 hours a day and backwash 3 or 4 times a day for
quickest results. Green or cloudy water will quickly clog a filter,
therefore you may have to backwash your filter many times a day until
the pool clears. THIS IS NORMAL ! Remember, you cannot over-backwash
a pool filter. The more you run your pool, and the more you backwash
the filter, the faster the pool will clear up. If you have a D.E.
filter, remember to add new D.E. to the skimmer closest to your filter
after each backwashing. A D.E. filter is more work than a sand filter,
but the D.E. filter will clear a green pool about 50% faster than
a sand filter.
- If you follow these instructions and your pool does not clear up
within 4 or 5 days, your filter may not be functioning properly. If
this is the case with your pool, have the filter system checked out
by a professional. The pool will never clear up if the filter is not
working properly !
- Once the water does clear up, you will most probably see debris
on the pool floor (dead leaves, algae, etc.). If there is only a small
amount of debris present, you may want to vacuum it up using your
own pool vacuum system. If there is a lot of debris on the pool floor,
you should have the pool professionally POWERVACUUMED. This will save
a lot of wear and tear to your filter system, as well as assuring
that no debris gets clogged in your pool pipe
