Not quite. Sure the peroxide is pushed out but as it leaves the plexiglass container due to the action of the catalysts breaking it down and pressuring much of the rest of the peroxide the existing peroxide is broken down by the ceramic beaker or in the case of the smaller Oxydators the ceramic base. Some peroxide will still exit the Oxydator depending on the % of peroxide used along with the number of catalysts. The % of peroxide used is an important factor.So basically, its a slow dose of h202 depending on how many catalystis are producing gas to push out the h202 from the bottom. Then the h202 is broken down in the water column.
