Hi Minichu



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 0.5 liter zeovit in a Zeo Reactor. Water flow around 55 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. Alternatively place the same quantity in a mash bag and place it in your sump as described moving the material daily for cleaning. 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. Running the material in a reactor makes the system much more effective to process nutrients.

2. Place 0.2 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 2 drops ZeoBac daily for the first 2 weeks, flowed by a 2 – 3 x weekly dosage of 2 drops. Dose 0.2 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.

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.

Not sure about the NO3 swings you have mention, it is unusual and maybe just a wrong result from your test kit ?

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