There was a study done where the stones were analyzed after 5 days, then again after 47 days of use in a tank. I have pasted the translated study below. The numbers under each element are the concentrations after 5 days, then after 47:

Zeovit (from Korallenzucht , Coburg )
Investigation report by Dipl. -Ing. ( FH) Lars Sebralla
www.lars - sebralla.de
Problem:
In salt-water aquariums various substrates for filtering and removal of phosphate can be used. A filter material is Zeovit the company Korallenzucht from Coburg . It should also reduce the phosphate content in the water. But from what is Zeovit and how much phosphate is adsorbed by the application?
Zeovit after use (from Korallenzucht , Coburg )
Scale 1 mm
Sample preparation:
The sample was used and used by Robert Baur according to the manufacturer .
After 5 and after 47 days , a sample ( about 100 g ) was removed . The respective sample was rinsed five times with deionized water, dried at 110 ° C and ****genized.
The sample material was provided by Robert Baur free of charge.
Experimental parameters ( personal communication from Robert ) :
Aquarium volume 988 liters
Amount of sample 2 liters Zeovit
Filter EHEIM external filter
Flow rate 950 l / h
Period of use 12.01. - 28.02.02
Water change 45 liters every 7 days ( as before )
PO43 - Start 0.35 mg / L
PO43 - end 0.046 mg / L (Merck Aquaquant )
Phosphate no
Kalkwasser no
Trace elements no , no iodine. In part, trace elements and amino acids are in the bottle Food of the manufacturer
Activated carbon 800 gr of the company GroTech in the first 4 weeks
The first 14 days of addition of bacteria and food , according to the manufacturer's instructions directly into the aquarium. After 14 days, only the Zeovit was contacted completely changed ( without feeding ) and after the study.
Notes to trial ( personal communication from Robert ) :
Growth is very good, colors to not have a great improvement . But with the colors we have in itself not a problem.
Where you really have to say that some animals were already brown before 0.37 mg / L phosphate noticeably relax and show growth tips.
The importance of using good filter carbon. In 1000 liters 700 -1000 g for 4 weeks.
Nitrate is actually also fallen in 6 weeks , initially 37 mg / L after 6 weeks then 0 mg / L. But you can not leave , because in exchange of the zeolite , the value again went upstairs.

Conclusion:
Zeovit consists for the most part ( besides oxygen ) of aluminum , silicon and potassium. Both after 5 days and after 47 days of usage duration no adsorbed phosphate could be detected on the Zeovit . The phosphate content fell in the water yet of 0.35 mg / L to 0.046 mg / L ( personal communication from Robert ) . Water samples for screening analyzes were not available.
A significant depletion (Simplified Entry in water) in Zeovit was in iron ( 4.400 mg / kg ) and calcium found ( about 3,100 mg / kg).
The high sodium and chloride content despite five times rinsing with deionized water is an indication of a large surface area inside.
Outlook:
Robert will collect bacterial sludge and Abschäumerkonzentrat and these samples are then assayed for phosphate. These samples are from since June 2002.
Comment by Thomas Pohl ( coral breeding , Coburg ) :
The Zeovit method is not a method for snap shots, all the nutrient status is degraded , including phosphate and nitrate. This can take several months depending on the strain and supplementation of the water. How indeed can be seen from the analysis , no nitrate and phosphate is bound in Zeovit , this is nothing new and known , but broken down by biological means , consumed and skimmed off , so this also works very slowly and takes the necessary patience , the delivery of iron I do not see as a problem, because in our plant iron is already for a long time can not be measured , and this is even supplied one , iron available in the form of , among other things available in ZEOfood . The Calziumaustrag will not be a problem , because with recommended small water changes this minimum discharge can be compensated without further ado .
