Yes, you can put too much shock in a pool, and it is crucial to follow the directions on the product you are using. Adding excess shock can upset the chemical balance, make the water cloudy, have adverse effects on swimmers, damage pool equipment or surfaces, and even encourage certain types of algae to grow. If you have over-shocked your pool, perform a water test and adjust the chemicals as necessary. The pool's chemical balance will eventually return to normal as the excess chlorine dissipates over time.

Yes, it's normal for pool pumps to make noises—like a humming or gentle rumbling sound. But if your pool pump is making loud noises, then this could indicate an underlying problem. Sounds to keep an ear out for include grinding, whining, screeching, and banging noises. Also, pay attention to any new or louder sounds emanating from your pump.

Yes, salt water pools are more expensive than chlorine-based pools because they require a more complex system than traditional, chlorinated pools. This added complexity means more skilled labor and a higher investment upfront. Also, if you need to repair a salt water pool, finding a contractor with the needed experience is generally more time-consuming.

The generator in your saltwater pool conversion kit transforms sodium chloride—the same salt as table salt—into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.
