Quick Overview

ZEOvit System Guide

KZ Product Guide

ZEOvit is a unique balanced mix of zeolites and one of the big four (ZEOvit, ZEObak,ZEOfood, ZEOstart) required for the standard ZEOvit ultra low nutrient system.

This system is designed to maintain maximum coral coloration, growth and health. The system requires one liter of ZEOvit media per 100 gallons of water and should be replaced every 6-12 weeks depending on nutrient load.

  • Use in a ZEOlite Reactor

  • If possible, agitate media daily

  • Maximum flow-through 100 GPH - do not exceed

Full Details

Korallen-Zucht  ZeoVit System is designed to maintain ultra low nutrient levels similar to the ocean reef habitat our corals thrive in naturally. As long as there is enough light, maintaining ultra low nitrates and phosphate has shown to increase coral coloration, growth rates and vitality.  All you need to get started with the Zeovit system is a reactor and the “Basic Four:”


  • Zeolites – The KZ ZEOvit ZEOlight mix is the primary media used in the reactor. The mix consists of three different zeolites chosen for their ability to reduce toxins in a balanced manor. 
  • ZEObak – This is a liquid additive containing a variety of bacterial strains that form the proper chain for nutrient reduction.  Used to introduce and maintain healthy populations of the desired bacteria in the ZEOvit system.  
  • ZEOfood  –  This is nutritional supplement for the corals. ZEOfood is primarily composed of amino acids and vitamins which enable corals to uptake necessary nutrients and  leads to a natural brilliant coloration.
  • ZEOstart – Promotes the reproduction of all nitrifying bacteria in the aquarium to help the system naturally remove phosphate and nitrate.


So what about all of the other Korallen-Zucht additives? Most of the other products are designed to further increase color, growth and vitality but are generally considered optional products that would be used after the initial stages of implementing the KZ ZEOvit system using the “Basic Four.”

  • Indispensible By Dan on 4/13/2017

    Have struggled for over a year with my tank and could not get corals to survive without having algal blooms. Tried overdoing skimming, red sea carbon dosing, phosphate media, well planted refugium. Zeovit was my last hope before tear down and it saved my tank. More daily maintenance but about one minute a day total. Water changes take about a half hour. Total weekly maintenance less than an hour. Was doing much more before and handling emergencies all the time. Would never start a tank without it, and I've had a few so far.
  • Near 0 nutrients By MHood on 3/26/2017

    Have been using for about a month. Nitrates and phosphates have remained near zero right from the start.
  • New build results good so far By Smo on 9/22/2016

    Running the ZEOvit system on a new 65G reef tank build—my first. Was heavily influenced by the BRS 160 series so I thought I would give it a try. So far I am impressed with their products. The tank is currently cycling. I will update when it stabilizes and I can start adding livestock.
  • Excellent ! By Tanh on 7/24/2016

    Excellent...Fast shipping...
  • Drank the koolaid... no regrets! By Mike on 5/4/2016

    Decided to go with ZEO on my latest build, after running pellets for years on several other tanks. No regrets at all, getting color and growth unlike anything I have had before. Can be a little pricey but worth every penny when you start selling some of the most beautiful frags because your growth is exploding!
  • Great Stuff By Jono on 2/7/2016

    The results of this system speak for themselves. The only annoying thing about the zeolites themselves is the amount of fine dust you get in the bag. You really have to wash the stones before to make sure not of that fine powder gets in your tank.
  • Best line for zeovit By eraser2001 on 2/7/2016

    Part of my zeovit system
  • Good By YeonHoo on 6/25/2015

    So much easier to keep all corals.
    Very nice~
  • Great product! By Theblennyman on 4/5/2015

    Converting to zeovit is the best decision I made in reefing. So much easier to keep all corals. This product is I think the best way of keeping a reef tank! Im sold! Zeovit all the way!
  • ZEO By Lawrence on 12/13/2014

    ZEOvites perform as stated
  • Excellent product been using for over a year By kenj on 12/8/2014

    I have been using this to drop my Phosphates by removing the precursors to lower.
  • An essential to zeovit By Leicaguy on 12/2/2014

    The essential of the basic 4, no phosphates no nitrates vibrant colors highly recommend this system and BRS usually is well stocked with the product line

Product Questions

Can a UV sterilizer be used with this system?
Question by: John Hildebrant on Jul 14, 2016 9:59:00 AM
Hi John,
The Zeovit system actually does not recommend running a UV sterilizer at any time. With the Zeovit system, you are using a bunch of bacteria to create an ultra-low nutrient system. Any UV sterilizer will easily destroy the bacteria that you are trying to culture in your tank and essentially combatting two different systems together that will most likely have negative effects.

how often does this media need to be changed and what is the procedure?do you change it all at once?
Question by: STEVEN FLETCHER on Nov 6, 2016 10:12:00 AM
Great question! This system is designed to maintain maximum coral coloration, growth and health. The system requires one liter of ZEOvit media per 100 gallons of water and should be replaced every 6-12 weeks depending on nutrient load. In which case, you would replace all of the media at once, and rinse the new media in water prior to adding back into the system. :-)

is there a hang on back reactor for nano tanks?will this work in a bag if shaken daily?
Question by: STEVEN FLETCHER on Nov 6, 2016 10:14:00 AM
Hey there! Check out the video below, where we covered this exact same topic on our BRS 52 FAQ series! :-)

Can I use this in a regular reactor instead? If so, can I tumble the media?
Question by: Alfred on Jan 17, 2016 12:19:00 AM
Great question!
This media will not work in a standard reactor as this is not a media which can tumble. It needs to be shaken with the use of a zeovit reactor with rod to shake the media one time daily. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 26, 2016 5:40:00 PM
What is the weight of a 1 liter bag? I assume converting the '1 liter' bag to a weight is ok bc liter is actually a volume measurement used for liquids as opposed to solids like rocks.
Question by: Todd Conner on Mar 26, 2016 5:09:00 PM
Great question!
The weight will be around 2 lbs but can vary from bag to bag. Typically with Zeovit you will use 1 liter media per 100 gallons. Feel free to let us know if you have any further questions!
