Pool Care Basics

Chlorine / CYA Chart

Perhaps a cornerstone element of TFPC is understanding the relationship between the chlorine in your pool and the stabilizer you put in to protect the chlorine from the sun. Generally, the more stabilizer, the more chlorine you need to maintain its effectiveness. The charts below show the recommended relationship for outdoor residential pools.

Pool Circulation Systems

The circulation system of a pool plays a major role in cleaning, sanitizing and heating the water. Above ground or inground, temporary or permanent, simple or fancy, all pools have a circulation system and they are all remarkably similar. Water is pulled from the pool via one or more skimmers and sometimes one or more main drains by an electric pump. The pump provides pressure to push the water through a filter, and other water treatment or heating devices, then back into the pool via one or more returns.

SLAM – Shock Level and Maintain

SLAMing your pool is the best way to eliminate algae, sanitize your pool and get your water crystal clear. If you have algae, or the CC level is above 0.5, or the free chlorine (FC) level is zero, you should SLAM the pool. You cannot do this overnight…it often takes several days to see it completed…no shortcuts. If you are maintaining proper FC levels there is no need to SLAM (or shock) weekly, or on any other regular schedule.

Mustard Algae

Mustard algae is a particularly persistent kind of algae, that appears to go away when you SLAM the pool normally, only to reappear as soon as you come back down to normal chlorine levels. It tends to grow in clumps on surfaces at normal chlorine levels, and varies from a true “mustard” yellow to green with hints of yellow. It can also grow free floating in the water if the chlorine level is low enough.
