A green pool is the result of a pool that is contaminated with algae. This is
usually caused by a low/no level of chlorine, no or poor circulation of the water, contamination of foreign
matter, or a combination of the above.
Super chlorinating the pool will kill the algae. The amount to use will depend
on the degree of contamination. If the pool just has small traces of algae, 1 or 2 jugs should be sufficient.
If algae has taken over for a matter of weeks, larger quantities will be required. Anywhere from 1 chlorine jug
to 8 or more (depending on the size of the pool). The longer the pool has turned, more chlorine will be
needed.
Keep the pump running constantly to mix/circulate the chemicals, and to remove
dead particles to the filter.
Follow the steps in "How to chemically balance your pool" and
re-adjust until all readings are within an acceptable range.
A saying in the trade is - there is no such thing as too much chlorine
!!! But, don't enter the pool until the chlorine level
has dissipated, and it is thoroughly diluted into the pool water. Generally speaking, next day is safe enough,
but check chlorine level is 5 or below - or skin irritations could occur.
The Algae should be killed within a day. Now, you are stuck with the dead
particles in the cloudy water, and on the pool floor (will require vacuuming). The dead particles are removed
by the filter. Particles must be removed by cleaning the filter daily, until the water is clear. If this is not
done, the filter will clog up and restrict circulation, leading to stagnation and the return of
algae.
Note - If the pool has been neglected for several months, consider
employing a pool professional to drain and acid clean the walls. Always ensure they are licensed and carry
insurance in case the pool "pops-out" of the ground.
