  • Works
Definitely lowers the GH. Gotta be careful stuff works fast on small tanks

  • 24 hour fix
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.

  • quick results!
My betta aquarium had the highest levels of hardness when I tested the water with the strips. and in just minutes, hour tops, the levels were already improving. I will check back in the morning and test the water again. But as of now, it looks like it's doing exactly what it's supposed to be doing.

  • It works
It works. With continuous use(48hrs), the water hardness dropped from very hard to soft.

  • Worked for 5 gallon tank
I have well water that is very hard. I put this pillow in the filter and just a little over 12 hours there was a dramatic improvement. I'll leave it in just a little longer next time. I didn't give 5 stars for ease of use for a few reasons. It's too big for my extra small filter pump and I couldn't find a smaller one so I did expect that anyways. I removed the carbon filter temporarily, then I just stuffed the pillow into the filter, but not so much as to cause the flow to be blocked. It will stick out at the top because you can't stuff the whole pillow in and left the cover off. When I was done with the pillow I put my carbon filter back in. The only other thing is that the pillow contents are not distributed well in the pillow cover. It wants to collect on one side. Despite all this it is sufficient for my 5.5 gallon set up. ... show more

  • Turtle rip it open
Turtle rip it open spent 2 hours filtering my water trying to get the sand like stuff out I think I got most of it after doing a water change but super mad that happened make sure to put it deep in your filter so if you have a turtle they don't get it. It did soften my water so that's the only plus

  • slightly worked
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.
