How Long do I have to wait to shock after I used Mineral Magnet?

If you don't have metals, it doesn't matter, with one exception: do NOT use calcium hypochlorite to shock.

The shock that I have is Sodium hypochlorite. Is that ok? The filter has been running 24/7 for 48 hours and I have backwashed twice after vacuuming, and will backwash once more before I shock. Thanks.

Sodium hypochlorite is just bleach -- it's fine.

I'm curious, what would happen if he did shock with cal hypo?

[PoolDoc]

Depending on how cal hypo was used, it could create a high chlorine zone that would degrade the phosphonate in the sequestrant, and release the metal. Following label directions, you tend to end up with cal hypo on the pool bottom, where that process would cause NEW stains.
