    25. Other notes - Wavemaker turnover 80-100x display volume, Return rate 5x total volume. Dosing liquids topped up when required (notified via Mobius). Fish fed twice daily with a mix of Hikari pellets and every 2 days with a frozen mix. CO2 scrubber attached to skimmer air intake.

    Please comment any constructive opinions you have towards my planned set up and how you think my Zeovit products should be utilised

    I suggest you follow these steps to get started:

    1. Put 0.45 liters of zeovit into the Zeo reactor. The water flow is approximately 180 liters per hour. Connect the reaction pump to a clock timer and run the reaction pump at 3 h on/3 h off/3 h intervals. Make sure the zeolite is not exposed to air when the pump is off. Clean materials daily. Leave the zeolite in the filter for 4 weeks until your first replacement. This is the first replacement interval, others may extend to 6-8 weeks.

    2. Put 0.18 liters of activated charcoal in the filter bag, then place it in the sink under passive water flow and change every 30 days. Wipe down the carbon daily to keep the surface clean. Most users will achieve perfect results with the korallenzucht carbon.

    3. Take 2 drops of ZeoBac daily for the first 2 weeks, 2-3 times a week, 2 drops each time. Take ZeoStart 0.18ml 2 times a day (morning and evening). Place them in front of the Zeo Reactor pump when the Zeo Reactor pump is on.

    4. Let's get Zeo SpongePower too - 2 drops every other day

    5. BioMate recommends that you also take @ 4 drops every other day for 2 -3 weeks, otherwise 2 times a week.

    UV is not compatible with the system, when you do ZeoVit program, turn off UV 2hr after dosing

    You can color the coral later with other products and ZeoFood if desired. Adjust your skimmer to skim off the wet, keep it clean to get as much out as possible. Change the water 5-10% weekly with good quality salt.

    Kalkwasser is not recommended
    When you start your ZeoVit system, make sure the elemental booster does not contain additional trace elements, it is best to get a pure supplement supplement, The kalkwasser will bind PO4 from the water column and this compound will accumulate at the sand and rocks for example

    Later on, full ZeoVit products are recommended over other brands, and for now let's stop all nutritional/coloring products as well.

    The basic parameters of the water look good, try to stay close to NSW in the following ranges:

    KH 6.5 – 7.5
    Ca 400 – 420mg
    Mg 1250 – 1300mg
    K+ ~ 380mg

    For malnourished environments, K+ (potassium) appears to be an important element. I suggest you get a test suite for that element too, and post your results​

      If I understand correctly, the current system doesn't seem to use any additives or methods of nutritional control, is that correct?

        Thanks for the reply Jacky. From reading previously I've seen many say that zeolite should have a constant feed of water, not be on and off sequentially?
        I've edited the as I do test for potassium, I typed P instead of K.
        The reason I run slightly elevated to normal seawater is because it is closer to the salt mix I use and it gives me margin for error

          With animals and corals already present in the system, doing it in 3 hour on and off intervals is fine.
          1. Accelerated bacterial colonization
          2. Slow and gradual pattern of nutrient reduction
          3. Acclimatization of animals to environmental changes
          4. Gradual changes in biology.

          If it is not possible to do it at intervals, reducing the recommended flow rate by 1/2 is another feasible way.

          Also make sure the salinity is correct, and the actual base water parameters are correct, adjust as slowly as possible to NSW

          the current system doesn't seem to use any additives or methods of nutritional control, is that correct?

            Understood 👍
            Coral uptake and TM Reef Actif are the methods to keep nutrients lower. There is no refugium, scrubber, media or other dosing that is used to control nutrients


            • #7
              Thanks, these messages are really important.

              Also stop adding TM Reef Actif when you are doing the full ZeoVit system. Take 2 drops of ZeoBac daily for the first 2 weeks, 2-3 times a week, 2 drops each time.

              Coral uptake - unfortunately I don't know what it is, I'm sorry.

                Hello Josh, as TM Reef Active is a carbon source it would be better to reduce the addition to 50% when you start with ZeoVit, reduce the rest step by step slowly to ZERO over the next 4 – 6 weeks.

                This should prevent you from a increase of PO4 as the ZeoVit components will take some time before they begin to process nutrients effective. If you use any additional products which contain bacteria or bacteria nourishing components stop dosing them in the same way.

                Make sure to switch off your UV filter when you start with ZeoVit as Jacky has already mention.

                  Sorry, I was googling TM Reef Active and it showed as nitrifier (powder) so I suggested to stop it, now I was wrong, it was a carbon source. Thanks G. for fixing the issue.


                  • #10
                    Hi Josh, since TM Reef Active is a carbon source, it is best to reduce the addition to 50% when you start ZeoVit and gradually taper the remainder to zero over the next 4-6 weeks.

                    I gave the wrong advice in # 7, I'm really sorry
