Default My 5 years tank - Help starting ZEOvit

Hi all,

I started my tank around 5 years ago but due to very frequent business trips I've never had much the time to dedicate.
Now I'm ready to go. No more business trips

I'm looking for a well known and supported method to follow in order to go with lsp and easy sps in the future.
Thank you for an help.

1. Gross water volume of your complete system (incl. sump etc.) - US gallons / UK gallons / liter 353 liters
2. Net water volume (incl. sump etc.) - US gallons / UK gallons / liter 283 liters
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)Deltec SC1455 rated for 800-100 liters tank
8. What are your actual PO4 and NO3 levels PO4=0.06 ppm, NO3=18 ppm
9. What are your actual Ca, Alk and Mg levels Ca=400/410 ppm, Alk=7 dKH, Mg=>1500 ppm (see note **)
10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.) 125 ml KZ Active carbon in a filter sock (passive water flow in sump) - 280 ml KZ Zeovit in a Zeolite reactor with around 70 L/h flow
11. Type of light (Watt, color temp, how old, etc.) Two Radion XR30W G2 fixture
12. What corals do you keep Just softies for now (Two Sarcophyton and one Litophyton arboreum).
13. Tissue color (light or dark) Few light areas without polyps for one Sarco. Normal color for the Litophyton
14. How long has the tank been running 5 years
15. Why do you want to use the ZEOvit system I'm looking for a well known and supported method to follow in order to go with lsp and easy sps in the future - Reduce nutrients, nitrates in particular.

16. Any supplemental dosing (type, amount, why, etc.) I'm using k+ and Ca buffer in order to regain the KH/Ca/Mg balance using a new salt (see note **)
17. Live rock (how much, how old, etc.) Yes, around 37 Kg of live rock
18. Any present problems Already mentioned.
19. Problem description Already mentioned.Bubble algae in the past solved with an help of a Naso tang.
20. What test kit do you use (how old, recently switched, etc.) Brand new test kit: Hanna checker for Alk, XAQUA for KH - Nyos for Ca, Mg and NO3.
21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.) None (except KZ Zeovit - see point 10)
22. Other water parameters and water stability (salinity, temp, etc.) Salinity=1.025, 27/27.5 Celsius deg. in summer 26/26.5 in other season
23. Which salt brand do you use now I'm using OceanLife BioTech Salt


** The Mg > 1500 ppm value is due to a bad salt lot (Royal Nature - No more used).

Hi Strazz



First of all I would recommend to download the dosing guide from:

http://www.korallen-zucht.de/files/z..._english-1.pdf

It contains a lot of useful information and will be helpful to get a feeling for the dosage.

First start with the basics products to decrease nutrients:

1. Place 0.7 liter zeovit in a Zeo Reactor. Water flow around 280 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 0.25 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 3 drops ZeoBac daily for the first 2 weeks, flowed by a 2 – 3 x weekly dosage of 3 drops. Dose 0.28 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.

Basic water parameters looking good, 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.

Hi Alexander.

Thanks for the valuable guideline !

At point 18 I forgot to reports few cyano (see attached image).

Just few questions:

1) Which is the best time schedule for the Zeostart ? Morning and evening in light off condition can be correct ?

2) What about Zeobak ? Should it be dosed away from Zeostart (for example around midday)?

3) May I create a small layer of KZ Aragonite ( 1 cm) just in front of live rocks ? Can it be dangerous (font of nitrates) ?

4) May I integrate Iodine if necessary ?

Thank you again

Best

Just dose ZeoStart once in the morning and once in the evening, does not matter if lights are on or off.

There is no special time to dose ZeoBac, you can dose it any time you like to.

ZeoStart and ZeoBac can be dosed in the same sump camber which does hold your ZeoVit reactor pump but always behind the skimmer-

A thin layer of sand does improve the biology, a depth of 2 – 5 cm usually works well.

As long as you have issues with cyanos do not dose Iodine, this will just speed up their growth, later you can dose this element to improve blue coloration if necessary.

Great Alexander, thank you again

I'm monitoring the KH/Ca/Mg balancing using the new salt for now.

I will start with the method in few weeks (updates to the post will follow).

Hi Alexander.

Just a very fast update:

I'm back ready to start.
I had to solve few problems concerning my equipments (sump and skimmer) getting a better stability.

Now I have a new skimmer (a DELTEC APF800 rated for 800/1000 Liters tank) and a new acrylic sump

Here my parameters (measured today):

PO4=0.05 ppm
NO3=1

Ca=410/420 mg
Mg=1410 mg

KH=~7.5
Salinity 35x1000

K+=~375 mg (KZ test is difficult to understand. I've done of my best)

Cyano still present (see the image)


Few questions:

1) I bought Zeovit, Zeobac, ZeoStart and the KZ carbon.
The Coral snow can be helpful in my case to fight against the cyano starting the Zeovit method ?


2) When is the suggested time to create a thin layer of sand (a depth of 2 cm of KZ aragonite) ?

Thank you

Strazz

If the system has still the same size you can start as described in post 2.

A 2 – 4 cm deep sand layer works very well from my experience.

Lets first see if the cyanos do disappear when you start with ZeoVit but if this does not work a treatment might be necessary. Please also make sure that the quality of your RO water is fine by checking it with a accurate TDS meter.

Hi Alexander.

I forgot to complete my post (sorry, I use to prepare the post text on a pc document) with another important change I've done on my tank:

One more drain line was added other than the sump change (for a leakage).

Due to the the new sump with compartments and the second drain that provides the correct water level in the tank (was too high before),
now I have the following system size:

Gross water volume : 338 Liters
Net water volume : 270 Liters

Thank you for a dosing review.

Best

Even if the water volume is a little bit lower you can continue with the dosing recommendation:

Thank you Alexander

Zeovit loaded in the reactor under timer for 3h on/3h off, KZ Carbon loaded in a filter sock and placed in a passive water flow area (skimmer compartment).

Ready to go now.

Few questions related to the Zeobac:

1)

You said in several posts that "Shelf live of ZeoBac, if kept in the fridge, is 6 month unopened and 3 month opened".

I have two 10 ml bottle here in my fridge with expiration date 02.03.20 and 12.04.20 so that both bottle expire later than 6 month.
Can you help me to understand the expiration criteria, please ?

2)

I've opened one Zeobac bottle. What about the odor ? It's not a pungent odour but I'm able to say that is not water In which way an expired Zeobac can be identified (I have no idea in which way the product is stored by the seller) ?

3)

Better dose Zeobac in front of the reactor pump like Zeostart or directly in the tank ?

Best

The self live of ZeoBac has changed a couple of years back from 6 to 24 month. The smell of the product is normal and can change over the time. Dosing in front of the ZeoVit reactor pump is ideal, just make sure to dose everything “behind” the skimmer.

Looking good, I would just replace the green hose with a silicon hose as they often leach softeners.

I will do for sure. Thanks Alexander

Talking about the weekly water change, which is the best percentage according to the Zeovit system for my 270 net Liters tank ?

I use to change 20 Liters/week.

Best

Usually 10% weekly works very well for a normal stocked system (corals). The regular water changes are dose to refresh consumed elements in a balanced way.
