Lowered my tank gh over like 8 hours. Don’t forget to rinse it first.

No, I do not recommend this product.

It worked exactly as advertised. It can be recharged with aquarium salts and you can use it several different times

No, I do not recommend this product.

Helpful?

Used it to bring down water hardness in a 5 gallon tank. 3 hours of use was good enough

Yes, I recommend this product.

Helpful?

Did not change water quality at all when tested during and after use. Price was high as well, almost $12.

No, I do not recommend this product.

Helpful?

Exceptional. I never expected it to work as well as it did. Can water be too soft? Buy it. You won't regret it!

Yes, I recommend this product.

Helpful?

I was told that this would help soften my water in my fish tank within 24-48 hours. I honestly forgot for a few days and when the water was tested again it had gone from hard/very hard to soft/very soft. Definitely does it's job efficiently! Used in an internal filter in a 30 gallon tank.

Yes, I recommend this product.

Helpful?

We only purchased one pillow to test on our 75 gallon tank. Mind I have extremely hard well water, full of iron and calcium, etc. and within 48 hours the gh had dropped significantly. From 300+ down to around 75-80. Using one pillow on a 75 gallon tank. Which is surprising considering 1 pillow is designed for upto 20 gallons.

Yes, I recommend this product.

Helpful?

I put this in my small (7.5 gallon) tank and within 12 hours my hardness issue was resolved. There was not negative effect on any of my other measurements. It exceeded my expectations.

Yes, I recommend this product.

I am trying to lower the hardness in my saltwater tank and can’t find any products to do so. Would this be okay to use or can someone recommend something else?

Does this work like water softener resin; specifically, does this resin exchange Na+ ions for Ca and Mg ions? If so, would a large amount of Na+ ions be harmful toSouth American catfishes (i.e., Corydoras, Rephael cats, Banjo cats, Bristlenose plecos...)?

4 years ago
I used it in my tanks that have Corydoras and other South America Amazon species with no ill effects observed. They have to be recharged with salt or they stop working. Na+ ions are not the same as NaCl. Ca and Mg ions are similar in not affecting pH in the working of these pillow resins. It is the compounds that form from the ions with other elements that affect water hardness. There are many books and articles on the efficacy and safety of these resins used to reduce water hardness and total solids as it effects fish health.

I have a 5.5g tank and it comes with a 10g HOB filter. I'm confused on how to use this product. Do I leave this in my HOB filter for 2 days (48 hours) and then remove it? or do I leave it in my filter the whole time?

Can this be used with a sponge filter and does this effect snails (nerite) and shrimp? I am getting my 10 gallon betta tank ready for some shrimp. Buying more plants and some driftwood. Can shrimp stand the pillow, can it be used with a sponge filter?

Yes, this can be used with a sponge filter along with snails and shrimp.
