  • Looking to make the Zeovit switch. Does my tank qualify?

    1. Gross water volume of your complete system (incl. sump etc.) - 150 US gallons
    2. Net water volume (incl. sump etc.) - 110 US gallons
    3. Are you using a CaCO2 reactor or other technique- Yes
    4. Are you using a PO4 reactor (how long, how long ago, etc.)- Yes, 5 years
    5. Are you using Ozone- No
    6. Are you using UV- No
    7. What skimmer are you using (type, rated water volume)- I have 2 (Reef Octopus 152-s 6" up to 150 g and AquaMaxx ConeS up to 90 g)
    8. What are your actual PO4 and NO3 levels- PO4 0.05 and NO3 less than 10
    9. What are your actual Ca, Alk and Mg levels- Ca: 450 Alk- 10 dKH
    10. What filtration method do you use- Refugium with chaetomorpha
    11. Type of light (Watt, color temp, how old, etc.)- 2 LED Radions about 4 years old
    12. What corals do you keep- Mixed reef
    13. Tissue color (light or dark)- Dark
    14. How long has the tank been running- 10 years
    15. Why do you want to use the ZEOvit system- to bring back coral color from brown. Achieve an ULN system
    16. Any supplemental dosing (type, amount, why, etc.)- no
    17. Live rock (how much, how old, etc.)- 80 lbs? Not too sure and most pieces are 8-10 years old
    18. Any present problems- nuisance algae and loss of coral color
    19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.)- hair algae, some Acros bleached, brown colored corals
    20. What test kit do you use (how old, recently switched, etc.)- Salifert
    21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.)- none
    22. Other water parameters and water stability (salinity, temp, etc.)- 32 ppt, 79 degrees F
    23. Which salt brand do you use- Instant Ocean Reef Crystals

    Very interested in this product to bring some colors back and get rid of lingering algae.

    Welcome to !

    First start with the basics products to decrease nutrients:

    1. Place 1.1 liter zeovit in a Zeo Reactor. Water flow around 120 US gallons per hour. Connect the reactor pump to a clock timer and run the reactor pump with a 3 hour on / 3 hour off / 3 hour on interval. Please make sure the zeolite is not exposed to air while the pump is switched off. Clean the material daily. Leave the zeolite 4 weeks in the filter until you do the first change out. This is the first changing interval, others could be lengthen to 6 – 8 weeks.

    2. Place 0.4 liters activated carbon in a filter sock and keep it in a passive water flow in your sump, changed every 30 days. Knead the carbon daily to keep the surface clean. Most users get perfect results with korallenzucht carbon.

    3. Dose 4 drops ZeoBac daily for the first 2 weeks, flowed by a 2 – 3 x weekly dosage of 4 drops. Dose 0.45 ml ZeoStart 2 x daily (morning & evening). Dose those in front of the Zeo reactor pump while it is switched on.

    Later on you could use the additional products for coral coloration. Adjust your skimmer to skim wet, keeping it clean to export as much as possible. Do a weekly water change of 5 – 10 % with a good salt.

    With the system it is not recommended to use a PO4 absorber. I would recommend to remove 1/3 of the absorber if you start with zeovit, than reduce the rest over the next 6 – 8 weeks step by step to zero. If this is done keep a eye on the PO4 level which should not increase.

    If the chaetomorpha algae stop growing it might be the right time to remove them before they start to die off because of the low nutrient concentrations.

    Basic water parameters are not 100% ideal, lets adjust them slowly before you start with the the system and try to keep them as stabile as possible close the NSW in the following ranges:

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

    For a nutrient poor environment K+ (potassium) seems to be a important element. I would recommend you to get a test kit for this element also, posting your results.

    This is a start-up dosage which might have to be adjusted later.

      Thank you for the response! The biggest thing for me is that I don't have room for the Zeo Reactor. Can I get away with replacing the phosban media in my Two little fishes reactor with the Zeovit? Is there a way around using a reactor at all?

        If the material is used in a reactor it does work more effective so my recommendation is to use a reactor. You might temporary use the PO4 absorber reactor in the main display until you remove it completely to have additional space for the ZeoVit reactor in your sump. Maybe a DIY reactor would be a possibility as you can vary with the size:

        Just using the PO4 reactor reactor might be difficult as cleaning the material daily is not working really good.
