  • Works but expensive!! By on 4/7/2017

    I use with an old BRS reactor, on my 55 gallon tank it lasted about three months, but with my 110, and a bigger skimmer, it won't last half that long, might be too expensive to keep buying!
  • Works well but $$ By on 2/21/2017

    It worked great from the start. pH went from 7.80 to 8.10 to 8.2 at night to 8.35 during the day. That said I had to change it every week which was going to get expensive. So I use the CO2 scrubber to the skimmer at night to keep pH swing minimal and ran a line from outside to my skimmer during the day. Keeps pH from 8.1 to 8.35. Now only changing it every 10 days to 2 weeks.
  • AMAZING By on 2/5/2017

    I have a 220 gallon tank. I have tried just about everything out there to get my ph up. with in 48 hours i was at a 8.3 my tank has ran at 7.8 to 7.9 since i set it up 6 months ago. i was tired of doing huge water change. trying chemical. it would always raise up then fall back to 7.8. i had a old media reactor laying around and figure i would try this stuff. i can finally add my calcium reactor and feel better about my ph levels.
  • Great product By on 1/27/2017

    I have used this product on my skimmer air intake and it has worked extremely well. It has kept my PH between 8.2-8.3. I change it out every week as its looses its effectiveness towards in about that amount of time. I use in conjunction with a two part dosing regime which I have on dosing pumps.
  • Works well, but its pricey By on 10/25/2016

    Works as described. Keeps pH up with my Calcium Reactor and low tank pH. I have to change it every 6 days though so its got a high price tag associated with it. I might try extending the intake line to a different room in conjunction with this product in order to extend the life.
  • PH up and stable By on 10/1/2016

    before I started using the co2 absorbent my ph was a low of 7.85 & a high of 8.15. Now its 8.09 overnite and 8.30 during the day. Great stuff and lasts longer than I thought it would.
  • IT Works! By on 9/27/2016

    Running on JBJ 28 gal NanoCube through Reef octopus HOB 90 cone skimmer air intake.

    Ph consistantly at 8.3. This product raised my ph to 8.3, and as a bonus eliminated the ph swing.

  • Excellent By on 4/14/2016

    If you have low PH issues this is your easiest fix. I hooked mine up to my skimmer and converted a BRS GFO/carbon reactor to put the media in and works like a charm. Before my PH peaked at 8 and the low point at 7.7. Now with the media it peaks at 8.3 and the low point is 8.1.
  • Product Works as Advertised By on 3/28/2016

    Hooked it to my skimmer air intake using reactor...pH increased in about 48 hours from 8.0 to 8.22 and held constant
