I was asked before how I removed the metal from my Nature 2 Fusion mineral cartridge and I found an old one thought I would take some photos so that it might help others in a similar situation.
The Nature 2 Fusion mineral pack adds copper and silver to your pool. Copper can stain your pool and turn hair green in large quantities. Also, if you switch to the TFP way, you won't need this mineral pack. Leaving the mineral pack in for long periods of time will cause rust to form and it will cause stains.
Taking the metals out of the mineral pack took me about 15 minutes which included unscrewing it, getting tools from my garage, taking photos and putting part of the of the empty cartridge back into the Nature 2 Fusion.
First, remove the mineral pack from the unit.
Second, break the grey ring at the bottom of the mineral pack. This will make it easier to break apart the darker blue covering that holds the bag of minerals.
Third, break apart the dark blue cover so that you can remove the bag of mineral balls. It is okay if you break part of the dark blue cover, just make sure that you don't break the grey top and the part of the blue cover that attached to the grey cover.
Fourth, once apart, clean the part that is going back into the unit, as shown as the blue and grey piece at the top of the first photo. You don't want to introduce copper and metals back into the water
I hope this tutorial helps someone else.
