    I'm so surprised........2 days and nobody. You guys all rely on mechanical equipment too much. 60% of UK reefers use NNR ( Natural Nitrate Reduction) systems. They've been keeping Marine Fish 15yrs longer than Canada and 10yrs longer than the US. Any input would be greatly appreciated!! Opinions??

    The only mechanical filter on my system is a big honkin skimmer.

    I rely on liverock and a proper feeding regimen to keep my nitrates at 0.

    I will be using a plenum type sand filter within my refuge. I intend to go with mangroves to control nitrates along with a medium size skimmer and moderate feeding. Water changes is a given.

    I think that's the case for alot of the reefers here at RC. The skimmer is the only piece of equipment used to filter the water. I myself am not going to have a skimmer on my 10G nano but will be doing weekly 10-15% water changes to export nitrates and to replenish trace elements.

    The aragonite I used is a tannish color, came from Utah. 250 million year old reef!! Anyone know where to get this stuff now? I set up over 10yrs ago and can't find it anywhere. They say glacial water is pure! Ha!

    Seachem has some interesting brownish aragonite substrates.
    I use a combination of shallow sand beds and n.n.r. (or plenum) system as well as macro algea fuge and I'm just adding some mangroves at the moment. I like to use as varied a system as possible. I also have a monster skimmer, but that's it for filtration.

    Wow reefmutt, I guess you'll never see nitrates in that tank, and you could have fish bumpin noses!! Awesome! Thanks for the aragonite info, I'll check it out. That skimmer will end up back in the box in a few years.
