Yes, it's not so much the model of Oxydator but the % of peroxide used along with the number of catalysts. A smaller Oxydator like the mini using the same % of peroxide and number of catalysts will work similar. However the peroxide will last a lot shorter due to the fact it holds less peroxide. An Oxidator A with 9% and 2 catalysts will last about 10days before it will need refilling give or take a day or 2 either side. Temperature also plays a part in peroxide use.So the size "A" should be good? Thanks
