API Aquarium Canister Filter Filtration Pouch with Water Softener Pillow - 1-Count Bag

Shelby: I have well water and needed some help. The pillow definitely helps with hard water. But I'd recommend to use it sparingly. Especially with planted tanks. I usually put the pillow in a bucket of water with and air stone to use for my next water change.

Colin S.: just 24 hr in a 10 gal returned to normal levels of hardness!

Alex Cobarrubio: Definitely lowers the GH. Gotta be careful stuff works fast on small tanks

13scares: We have hard city water and using this in our filter we were able to go from off the charts hard to pillow soft in 24 hors for our 20 gal tank. Super great performance and did not effect our set up or flow. Great value if you want to use tap since it is reusable.

Rose: It lowered the hardness a little but I really saw a difference when I added driftwood to my tank, and not the driftwood that you'd find in your backyard. I used aquarium driftwood like African root. I boiled it a few times to get the tannins out and so far so good.

WordCraftDesign: It does work but its really expensive and you can only use it 3 times.

Freya Martinez-HurtadoFreya Martinez-Hurtado: Had the little pillow in the tank for 24 hours only as I wanted to soften the water a bit. I was very skeptic but seems to have done the trick? (I wanted to soften it “one square “). I know RO water is better but this does work (someone told me it wouldn’t). - my tank looks cloudy because it’s a new tank that’s currently going through a bacterial bloom -

glen lander: Worked great, within 24hours hardness had reduced from 500 to around 300. I have seen however the salt to replenish these are fairly expensive.

Amazon Customer: Simply, it works after 1 Day with only one in my filter cartridge it nearly halved my GH from over 600ppm (30 degrees) to 350ppm (17 Degrees). Considering this treats only 70L of water and my tank is 110L and it was only in there for 24H im very impressed. After adding another one and after 48 Hours it went down to 142ppm (7Degrees)

Only reason for 4/5 Stars is its kinda expensive considering you have to replace it after 3 uses but honestly the most expensive part is the salt you have to buy to recharge em. Kinda wish API would do a little kit with the pillow and the salt for a small discount
