Here is the princips for an Oxidator A - its the same for Oxydator W
Oxydator A
Oxydator W
The plastic container is filled with H2O2. Catalyst is placed inside and the orange cap is tighted. The container is placed upside down in the clay cannister. The clay cover is placed above the plastic container in the clay canister. The whole package placed in the sump or aquarium
The catalyst slowly breakdown the H2O2 in the container into H2O and O atoms -> the O atoms form oxygen gas (O2) and slowly press out pure H2O2 (liquid) into the space between the plastic container and the clay cannister into the water (sump or aquarium water) The clay canister serve as a second catalyst and further break down some H2O2 into water and oxygen - but some pure H2O2 will enter the aquarium water. This is an genius dosing equipment and the dose per time unit is depended on the strength of the H2O2 solution and how many catalyst you use. In a large aquarium like yours - Which strength of H2O2 you should use - you need to test this out. If you dilute a strong solution - be careful to use RODI water of high purity because chlorine and amino chlorines will act as a catalyst too. In an unknown aquarium system I would start with a low concentration and few catalyst - maybe in you case 6 % and 2 catalyst. If it works well - rise the concentration - but I have not rise it over 12 %. When you have 12 % concentration - and still work well - use more catalyst. If you use it as a parasite/pathogen remedy you may rise the daily dose in the way that you get more not catalyzed H2O2 into the water. The water will slowly catalyze the H2O2 in the water and create free oxygen radical which are you death patrol against pathogens. The W is higher than the A. hence have a more effective second catalyze process than the A model. This means that you have to test your setup and see what´s most effective. The yellow substances in the water will be affected by the peroxide dosing, hence if you get a more clear water - you know you minimum dose (concentration plus number of catalyst)
Hope this helps you
