Fixing a green pool – Kingston Pools and Hot Tubs – Knapp’s Pools and Hot Tubs

Fixing a algae infested pool.

It never ceases to amaze me that people continue to hope for a miracle fix of a green pool overnight.  It didn’t turn green overnight.  There were weeks of forgotten water care prior to a pool turning green with algae and it will take a little bit of time to clear the water.  It will happen for sure but let’s talk about ‘why’ the pool turned green in the first place.

Lack of sanitizer allows algae to begin to make an appearance.  Make sure you follow a weekly regimen of water care.  Keeping sufficient amounts of chlorine in the pool is necessary. (1-3ppm) You can do this using chlorine pucks/sticks or you can use a sanitizer such as salt ( which uses a chlorine generator (also known as salt cell, salt generator, salt chlorinator) which uses electrolysis  in the presence of dissolved salt (NaC1) to produce hypochlorous acid (HCIO) and sodium hypochlorite (NaC1O).  As such, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.

When you have algae it is very important to first brush the walls and floor of the pool to dislodge the algae, next vacuum dead algae to waste, shock the water (I would suggest you use triple the shock) apply a good algaecide and then we have a product called Dazzle Clear Rebound which is our most effective product for accelerating the destruction of algae and for
digesting the dead algae to return the water to the desired clarity.  Dazzle™ Clear Rebound digests dead algae, removing it from the pool.
Balancing the water is also critical to proper water maintenance.  We have a very easy program for weekly water care and work with you personally to keep your water clear and healthy all season.
