  • New Tank -- Confused About Dosing Instructions

    Hi everyone,

    I am setting up my second ZeoVit tank, but I seem to be struggling with getting the water parameters to stabilize. I think this is partially a byproduct of the fact that I've seen three different sets of ZeoVit "starter" instructions each with different dosing recommendations. This is a nano tank, so I'm worried that I might be overdosing and want to get the recommendations of the experts.

    1. Gross water volume of your complete system (incl. sump etc.) - 20 US Gallons All-In-One Tank
    2. Net water volume (incl. sump etc.) - 20 US Gallons
    3. Are you using a CaCO2 reactor or other technique No
    4. Are you using a PO4 reactor (how long, how long ago, etc.) No
    5. Are you using Ozone. No
    6. Are you using UV No
    7. What skimmer are you using (type, rated water volume) eShopps Nano Skimmer
    8. What are your actual PO4 and NO3 levels Nitrates: 10-20ppm / Nitrites 2mg/L
    9. What are your actual Ca, Alk and Mg levels 9.7 DKH / 460 cal
    10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.) Filter pad in the first chamber, carbon in the third chamber, skimmer in the second
    11. Type of light (Watt, color temp, how old, etc.). Kessil A360X light. Mounted 8" above water and intensity turned down to 15%
    12. What corals do you keep Intend to keep a mixed reef: Zoas, LPS, SPS. No coral currently as this is a new setup
    13. Tissue color (light or dark) N/A
    14. How long has the tank been running 18 Days
    15. Why do you want to use the ZEOvit system. Stability, Low-Nutrient, High growth & color
    16. Any supplemental dosing (type, amount, why, etc.) Will dose BRS 2 part when ALK/CAL levels dictate
    17. Live rock (how much, how old, etc.) 20# of new ocean live rock. Added to tank during setup
    18. Any present problems Some brown diatom-like algae on sand and rock. Nitrite levels don't seem to be dropping / Nitrates are still high
    19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.) Above ^^
    20. What test kit do you use (how old, recently switched, etc.) Hanna Checker, API test kit, Red Sea test kit. All are new
    21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.) See below
    22. Other water parameters and water stability (salinity, temp, etc.) salinity is 35ppm. Water is 78*F
    23. Which salt brand do you use. Tropic Marin Pro Reef Salt

    Current ZeoVit:
    I currently run Zeovit material in a mesh bag (0.2L of material) that I shake daily. I also have ZeoBak, ZeoStart, and ZeoFood. When I started the tank, I dosed according to the instructions found here: After a week, I had a considerable amount of a brown diatom-like algae on all surfaces. Did a 20% water change and some more research, as I didn't have this problem on the previous Zeo tank I setup.

    Then I found these instructions:

    After searching on this forum, I also found a post by G. Alexander that recommends a dosing regiment that is a mix of the two instructions. Now I'm confused.

    The first setup guide suggests daily dosing of the various additives for the first 14 days, before moving to the maintenance dose, but a pause if brown algae is seen. The second set of instructions has an initial starting dosage for ZeoBak, food, etc and then immediately goes into the maintenance schedule after a short dosing break. Finally, the instructions that G. Alexander posted suggest a hybrid approach where you dose for 14 days and continue to dose through the algae bloom.

    Help!? I paused dosing 48 hours ago in hopes of stabilizing things and getting the Nitrates and Nitrites to come down, thinking that there were too many nutrients in the tank. I have yet to see a drop in either parameter, but just did another 25% water change and am waiting to test again. How long should I wait to resume dosing, and when I do resume, what dosing schedule would you recommend?

    Thanks in advance for the help on my small nano tank!

    Zeo Food7 was used in the old version, and Zeo Sponeg Power was recommended in the new version. After 14 days of circulation, 1 drop of Zeo Bac = 25 US gallons / 3 times a week. Zeo Start 0.1ml = 25 US gallons x 2 (daily, morning and evening) , Zeo Sponge Power 1 drop = 25 US gallons every other day. 20 US gallons are less than 25 US gallons. Based on 25 US gallons, the zeolite material is about 0.2 liters, and the amount of Zeo activated carbon is about 0.1 liters (passive flight using a mesh bag)

      Welcome to !

      Basically I would recommend you to get a small reactor for the ZeoVit material, maybe a DIY project would be a good, easy alternative. You can find some ideas in this thread:

      Because of the dosage I would recommend you to continue as follows:

      ZeoBac – 1 drop 2 x weekly
      ZeoStart – 0.075 ml 2 x daily

      Lets skip dosing ZeoFood at the moment until the system runs stabile.

      Give the system some time now and keep the changes as low as possible. At the moment I would not add animals except herbivore like snails.

        Thank you G. Alexander. I will modify the dosing as you recommended. I am hoping to build a little reactor for the media soon, but space is limited in the tank so I was hoping to get things established and see how much space I have from there.

        PS - the Nitrates dropped to 5-10ppm overnight, but no change in Nitrites. Should I do another 25% water change today?

          Give the system more time, due to the new tank and the number of animals, the element consumption is not much, and the water chemistry is changing. It is recommended to start after the sixth week. With the low nutrition level, it is good to refresh the element balance



          • #6
            At the moment I would not do additional higher water changes, keeping changes low would be the best you can do at the moment to give your system time to build up a working biology.

              Thanks for the help everyone. Finally saw my Nitrates drop to 0 and Nitrite between 0-0.25.

              Over the long term, what would you recommend for dosing, and should I return to using the ZeoFood at some point?

              I plan to keep mostly softies and LPS to start, adding SPS in awhile.

                You can use the dosing recommendation I have posted also for the future. Once the system is running nutrient poor stabile you can add additional 1 drop ZeoFood twice a weeks. Later on products to improve coloration can be added also but this depends to how the corals are doing.
