I bought the Oxydator AWhich model did you go for and make sure you buy a couple of spare catalysts.
Choose which % H2O2 you are going to use and how many catalysts.
Give me your water volume +/- and I can compare it to what I run / use.
Will be using 12% hydrogen peroxide
It will be going into a system of 130 gallons.
At this point I'm unsure if I need to use both or just one of the catalysts it comes with.
Also can I run in my sump or the DT only?
