Pool water turns redish brown after chlorine shock treatment

Postby Pool User » Tue 13 Feb, 2007 00:34

I shock treated the pool with chlorine today and the water turned to a redish brown color within 20 minutes. What might cause such a reaction?

Any help on this is highly appreciated and thank you

This usually indicates iron. You will need to shock very heavily to fix this up.

thank you for the hint. What do I heavily shock it with? Muratic acid, more chlorine?

Sounds like iron in the water. Shocking with chlorine will oxidise all the iron to "rust" which then settles for easy vacuuming.

Have your water checked for iron, which may eventually leave nasty stains on the pool's surface if not controlled.

HAVE TH WATER CHECKED FOR IRON AND THEN GET A SEQUESTRIANT AGENT IN YOUR POOL. ASK YOUR POOL STORE FOR A PRODUCT TO TAKE OUT IRON SUCH AS JACK'S MAGIC OR PROTEAM METAL MAGIC
