What does this mean that its rechargeable? What does it take to recharge it?
Answer by ChewyJun 04, 2021
API Water Softener Pillow can be recharged and re-used up to 4 times before purchase of a new one is necessary. When its effectiveness begins to lessen, dissolve 3 tablespoons of aquarium salt in 7 ounces of tap water. Rinse the pouch in this tap water, then soak it in salt solution for 2 hours. Place back in the filter as is, there is no need to rinse it. When not in use, store the API Water Softener Pillow in recharging solution. Do not let it dry out. Replace your API Water Softener Pillow when it ceases to function properly after recharging.

So it says it can be used for aquariums up to 20 Gallon.... so do I have to use multiple in my 55 gallon? and is one safe for my five gallon tank?
Answer by ChewyJul 31, 2017
This pillow will soften water up to 20 gallons. For a 55 gallon tank, you'll want to use three pillows. For a five gallon tank, you'll want to use one pillow.

Is it safe to use a ph corrector when using water softener pillow? Also, can i use a regular filter at the same time I'm using the water softener pillow?
Answer by ChewyFeb 06, 2020
As long as the Water Softener Pillow is in the water flow, removing any additional media should not be necessary. The Water Softener Pillow can potentially lower the pH, so we do recommend adding an appropriate buffer alongside this to keep the pH levels stable.

So I'm confused. So this product does not stay in the water? How do you know it needs to be recharged.
Answer by ChewyDec 05, 2021
This softener pillow stays in the water and must be recharged after 48 hours. To recharge: Dissolve 3 tablespoon of aquarium salt in 7 oz of tap water. Rinse pouch in tap water, then soak in salt solution for 2 hours. Place back in filter, there is no need to rinse. When not in use, store Water Softer Pillow in recharging solution. Do not let pillow dry out. Replace when Water Softener Pillow ceases to function properly after recharging.

Works Great for smaller tanks

Works great for smaller tanks 10 and 20 gallon. Bigger tanks not so much just better to use RO water and add minerals for Large tanks

Softens water for 10 gallon tank

I bought three of these pillows to alternate every two days before my weekly water changes. I’ve read about peat moss but I don’t like the tannins. I use one pouch for my 10 gallon Betta tank. Before the pillow, my water hardness was at 16 dGH. With the pillow, my water hardness is at 9 dGH (yay!). The hard part is remembering to place them in their recharging solution when not in use, so I’ll have to order a replacement.

Massive Ph Drop!!

Worked to soften hard water very well, but at the cost of acidifying all of my tank water! Not worth it; hardness wasn’t hurting my fish but the low ph definitely is.

Water softener pillow

API water softener pillows worked as advertised. Multiple pillows needed for large tanks.

No change after 3 recharges

I purchased two of these and followed the directions. To try this out I only opened one, but have since recharged it twice and it has made zero difference in my 55gal. tank.

Awesome Water Softener

My aquarium water was very hard. I used the pillow for an hour and the water tested very soft. I took the pillow out and air dried it for the next time.

Water softener pillow

This works great. I have very hard water always reading at 180, put this in my filter and within 12 hours, my GH was down to 60.
