    Works Great for smaller tanks

    By Obiewan on Sep 30, 2021

    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

    Massive Ph Drop!!

    By Hejo on Jun 18, 2021

    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.

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

    Softens water for 10 gallon tank

    By on

    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.

    Good solution

    This was really easy to use and quickly brought my aquarium GH levels to the appropriate level.

    No change after 3 recharges

    By on

    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

    By on

    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.

    No more salt chunks on top of tank

    Really like. Lowered the ph and is reusable. I bought one before but it was really big for my filter.
