Review: Use these - This stuff actually worked. I’ve been plagued by hard water ever since moving to my current home twelve years ago. My aquarium equipment has always gathered white buildup no matter how many softeners I tried. UNTIL this one! Absolutely zero buildup has stuck since I added one of these packs to my tank! I am so thrilled. Everyone in the tank seems happy and healthy and I’ve been using these for about a year now. Water clarity is crystal as always.
Review: It does soften the water. - It leaked everywhere. I took my tank apart. Collected the little chunks. Put it all in a sock and put it in the filter again. It definitely softened the water. But then I found out the fish store used local tap water which is hard so the fish I bought needed hard water and the snail's shell suffered from the soft water.

## Questions & Answers

**Q: Where exactly in the filter is this pillow supposed to go?**
A: preferably in your filter or somewhere with a lot of water movement

**Q: What is the recharging process?**
A: 3 tablespoons aquarium salt dissolved in 7 ounces of tap water, use a shallow dish.  Rinse the pillow after removing from filter area and soak in salt solution for 2 hrs.  Always store pillow in salt solution when not using.  Discard pillow when it is no longer effective (check the water hardness to verify.)  I use a plastic Chinese to-go dish, the white rectangular ones.

**Q: Will it stain water**
A: No, it will not stain water.

**Q: Does it hurt to leave the pillows in the filter until next water change? Will it shorten the life of the pillows (x's you can recharge)?**
A: The instruction I found online say that it should not be left in for long periods. And, you can recharge it with sunlight, if you use it for the period of time only long enough to get the change you are looking for in the water. Thanks my experience.
