  • Works as advertised By Mrod on 7/28/2015

    Very satisfied as it works as others have mentioned. My Phosphates were always a struggle with a nano tank and no skimmer - this is the first media to actually make a noticeable difference,
    Gradually coming down each week and happy with the results thus far!
  • Excellent GFO! By Pegasus on 7/27/2015

    I started with BRS HC GFO, and if the day comes, I will end with it as well. Rinses clean almost immediately, and does an outstanding job of removing PO4. Levels stay near-undetectable, even with my heavy feeding habit. IMO, it's worth the extra cost to not change it as often. 15% water changes every two months of so, and my fish and corals are thriving! Highly recommended product!!!
  • Great phosphate remover! By Ae86oni on 7/22/2015

    Good quality gfo! Does exactly what it's supposed to do. Keeps my phosphates in check. I did have 1 issue at first, but it was my fault. I was having an issue with it clumping together in less than a week, even though it got plenty of flow. After tons of research, I found out that having a low magnesium level will cause this to happen. Another tell tale sign of low magnesium is your pumps quickly getting covered in a calcium deposit. If you run a gfo reactor, make sure your magnesium level is in check. Will solve the problem!
  • Good GFO just very Expensive By Christopher on 7/15/2015

    I bought this GFO when i first started reef keeping. Keep phosphates at 0 always. However, it was a really cost to buy this. So I switched to RowaPhos, still good. But now have a small algae outbreak.. thinking about switch back! This GFO is amazing if you can afford!
  • Seems pretty great By Damon on 6/10/2015

    Virtually no dust so rinsing is quite fast. Fluidizes very well and doesn't seem to break down like RowaPhos... Also seems to pull a bit more phos compared to RowaPhos but not sure if this is fact or perception. Overall, I like it!
  • Works Great By Brian on 4/28/2015

    I use this for phosphate removal on both my 150 reef and my 65 gallon predator tank. I usually change it out every 6 weeks and use a reactor for it. I check my phosphate's weekly using a Hanna checker and rarely do I get anything above a .02.
  • Good stuff By John on 4/11/2015

    Seems to remove a little less PO4 than ROWAphos, but is much easier to use. Not much dust when rinsing before use. Works well in BRS deluxe reactor, slightly fluidized, without the sponges installed. Just started regenerating it, which seems to work well.
  • Good product By Tripp on 4/1/2015

    Using the high cap GFO. Can't compare it to standard, but it is very effective in PO4 removal. Definitely use a small amount when starting out. I used 1/2 of the recommended starting amount and built up slowly from there. Didn't have any issues
  • FRICKIN AWESOME By Wrath of Poseidon on 3/6/2015

    i have lots of fish lots of corals in a 150g can go 2 months with out what changes
  • Very Happy By Benjamin on 3/5/2015

    Been running the HIgh Capacity GFO for two years in two different tanks. On my 90gal. I have the BRS dual reactor with GFO and Carbon. Since running the HIgh Capacity GFO, my phosphate levels are non existant.
