Product Questions

I am looking to slowly trade out some of my rock in the display for marinepure in the sump to open things up a bit. Is there any ball park estimate on how many pounds of Fiji rock one of the 8x8x1 plates will replace?
Question by: wes on Jul 20, 2014 12:35:00 PM
Hey Wes,
Generally speaking the 8x8x1 plate is enough surface area to handle a 100g tank on its own, so you should have the ability to remove quite a bit of rock. Just make sure to do it slowly so that the tank has time to adjust and the bacteria that are getting removed have time grow in their new substrate.

Full Details

The media’s composition is similar to natural rock formations. MarinePure provides approximately 150,000 sq. Ft per cu. Ft (510 m2/L) of accessible surface area. The properties of MarinePure create a stable home for a dense population of beneficial bacteria that remove ammonia and nitrites from your aquarium. Some systems will also see a decrease in nitrates. MarinePure will work in sumps, trickle filters, wet/dry filters, hang on the back filters or directly in the tank.

  • 100% Tank Tested
  • Most technically advanced bio-filtration substrate
  • High usable surface area for beneficial bacteria growth
  • Open porosity means maximum bacteria exposure to contaminates and promotes excellent water circulation and less clogging
  • Designed specifically to target ammonia and nitrite removal and minimizes nitrates
  • Inert and chemically stable
  • Greater than 80% open porosity
  • Provides consistent water chemistry
  • Reduces tank maintenance
  • Able to support large fish loads
  • Can be cleaned, reused and sterilized

  • Waiting to see results By Wayne on 8/19/2015

    i bought it based on reviews and talking to the rep at a marine conference. It hasn't affected the flow in my sump but I am waiting to see how it affects my levels. So far it is exactly what was promised and it was easy to cut with a sturdy knife. Just make sure to rinse after cutting to clean out dust.
  • Good BUT seed it first. By Kris on 8/10/2015

    This is a great product. I used it in a sump on a drilled biocube 29. Only thing I would recommend is seeding it first in another tank before adding it to a smaller aquarium. My tank went through a small cycle after about a week of putting this in my sump.
  • Quality is obvious By Bill on 6/16/2015

    have not installed yet, but quality of product is evident.
  • Great Product and Performance By Dylan on 7/31/2014

    I bought the 8x8x4 after seeing a video online of scientists using the spheres in a lab. I put it in my sump while my tank was cycling and my ammonia went down very quickly and I have not measured nitrate in my tank since. This material is very porous, and I would recommend it to anyone that doesn't want to use a lot of rock in their display tank.
  • Bio pellet, plate review By Daniel on 7/18/2013

    The bio-plate is so soft! I was able to easily shape the plate and have put it in the top tray of my canister filter. Day one of this little experiment, no noticeable reduction in flow so far. Very cool product..
    Five stars on first impression and ease of use...
  • Great product By Robert on 3/15/2012

    This product is extremely light in weight and porous. When rinsed no water collects on the top of the pad or runs off the side.
  • Performance By Robert on 10/31/2011

    Along with using the Marine Pure Spheres, I put two of these on the bottom of the sump to support the egg create. Keeping these two submerged has dropped my nitrates to a safer range. All together, the system has 168,400 square feet of Ceramic Biomedia.
