Welcome to ZeoVit.

First-fill in the basic information about your tank so that we can learn more.

The phosphate level seems to be very high. It is difficult to say why at present. We don't know very well. Please also attach some clear pictures of the main display system and sump. The rock uses live rock or what kind of dry rock? What other equipment.

Since you use wet sand, this may take a long time and requires patience. It is recommended to change 10% of the water every week, which is the norm. If there are a lot of corals in the tank, it makes sense to change more water every week.

I estimate that the Net water volume is 320 liters

1. Put 1.25 liters of zeovit into Zeo Reactor. The water flow is about 320 liters per hour. Connect the reactor pump to the clock timer and run the reactor pump at an interval of 3 hours on/3 hours off/3 hours on. Make sure that the zeolite is not exposed to the air when the pump is turned off. Clean the material every day. Leave the zeolite in the filter for 4 weeks until you change it for the first time. This is the first replacement interval, other times can be extended to 6-8 weeks.

2. Put 0.3 liters of activated carbon into the filter bag and keep it in the passive water flow in the sink, and replace it every 30 days. Rub the carbon every day to keep the surface clean. Most users use korallenzucht carbon to get perfect results.

3. 4 drops of ZeoBac a day for the first 2 weeks, 4 drops 2-3 times a week. Take 0.4ml ZeoStart twice a day (morning and evening). When the Zeo reactor pump is turned on, add medicine to it.

4.Get Zeo SpongePower, 4 drops, every other day.

You can use other products for coral coloring later. Adjust your skimmer to skimmer and keep it clean to export as much as possible. Change the water 5 – 10% every week and use high-quality salt.

Wet sand is not recommended to be combined with the ZeoVit system. Dry sand is usually used as a shallow sand bed. Since there are animals in the system, we are currently unable to do anything. It takes time for Zeo bacteria to grow. Therefore, in the regular plan of Zeo, I have added more nutritional products to reduce nutrition. One drop, so that this process can be supported.

This combination (wet sand and Zeo system) may get algae and brown film, don’t worry, let’s see the follow-up development

The basic water parameters should be kept as stable as possible, and it is recommended to be at the NSW level

Kh 6.5-7.5
Ca 400-420
Mg 1250-1300
K+～380g

Thank you for the suggestions.
Aren't 1.25 liters in a 320 liters, too much ? The official protocol PDF is saying 1.0 liters every 400 liters

And what about coral grow ? It's common thinking, at least in Italy, that under zeovit protocol corals doesn't grow too much (much less than a standard tank)

I am very sorry, this is my calculation error, the net water volume 320L/0.8L Zeolite material quantity.I am really sorry

Regarding this question, I can tell you for sure, in the nutrient-poor water quality, and the biologically healthy environment. Corals absolutely grow wildly, compared to higher nutrition.

When you combine all your experience and ideas, this question is naturally not a question. If you ask me, I will answer you immediately (without much thought/no hesitation at all). When you have more "understanding" you will naturally understand.

Let me say 3 points:

1. Higher nutrient levels will hinder the growth of coral calcification. (Polyps are closed, no growth, reduced element consumption, such as KH)

2.Take KH as an example, when the level of nutrition (NP) is close to 0, it is close to the nutrition of the natural ocean in a balanced environment. Coral polyps are expanded and healthy. In my tank, KH is extremely depleted. I often test frequently, and over time with the growth of corals, I learned that the KH solution in my equipment has increased.

3.The appearance of coral is the best proof

Thank you for the clarification.
I've posted a sample draft plan for dosing, the post is waiting for a moderator approval (it was detected as spam)

**gandalf** · 09-23-2021, 11:47 AM

my dosage is good? i understood properly?

**jacky** · 09-23-2021, 11:48 PM

1. Put 0.8 liters of zeovit into Zeo Reactor. The water flow is about 320 liters per hour. Connect the reactor pump to the clock timer and run the reactor pump at an interval of 3 hours on/3 hours off/3 hours on. Make sure that the zeolite is not exposed to the air when the pump is turned off. Clean the material every day. Leave the zeolite in the filter for 4 weeks until you change it for the first time.

Hello Gandalf, Jackies recommendation are basically correct however to the lower net water volume of the system some corrections are necessary (ZeoStart). To give you a complete overview I will post some information which Jacky has posted already again to give you a “compact” recommendation:

For a net water volume of 320 liters I would recommend you to start as follows:

First start with the basics products to decrease nutrients:

1. Place 0.8 liter zeovit in a Zeo Reactor. Water flow around 320 liters 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 0.3 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 0.32 ml ZeoStart 2 x daily (morning & evening). Dose those in front of the Zeo reactor pump while it is switched on. As you already have SpongePower you can dose additional 4 drops every other day for the first 4 weeks, than change the dosage to 2 x weekly.

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.

Slowly adjust and keep the basic water parameters 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.

Many have issues with live sand in combination with ZeoVit, if you experience a constant film on sand / rocks or cyanos after you have started ZeoVit if might have something to do with the sand, just something to keep in mind.

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

Thank you all.
What's the difference between a live sand and a dry sand that will be colonized ? It should be the same, except that the live sand is already colonized

**G.Alexander** · 09-24-2021, 03:41 AM

The reason is not really clear but I would expect it has something to do with the kind of bacteria strains contained in the sand.

G.Alexander

**jacky** · 09-24-2021, 03:54 AM

Thank you G. for helping us fix better suggestions.

I try to reply to you with my own thoughts, but I cannot say that I am right.

Living sand usually contains bacteria and others. There will be conflicts between bacteria, there will always be competition, which affects/changes biology. The derived result is displayed in a certain form, such as algae, film, Cyano.

For example, adding different bacterial products to the ZeoVit system may disrupt this balance. The Zeo system has its own bacterial strain (Zeo Bac). I don't know what its ingredients are, but it must be a combination that best fits ZeoVit after experimentation and research.

And this best is also used for zeolite materials, the two of them help each other to synergize.
