DC Pools - Pool Cleaning Service

Yes you do! Even salt pools need it. The purpose of shocking your pool is to remove the chloramines and dead stuff floating around unseen in the water. When chlorine kills something it binds to it and becomes ineffective. Shocking removes that. 

The benefit of the salt water system is that it converts salt into chlorine. The only exception is your weekly shocking.

The right pH balance keeps things safe and healthy.  It also makes your eyes feel more comfortable under water as our eyes are 7.5 pH.  Your chlorine works better when your pH is in this range. 

Green algae is lighter in color and grows in large patches on the  water’s surface or the pool’s walls. It grows relatively quickly but is  easier to get rid of than other types of algae.

Black algae is  darker in color and will appear in scattered spots in cracks and  crevices throughout the pool. It is particularly difficult to get rid of  due to its ability to seep into porous materials and cause structural  damage that requires extensive repairs.
