Need a new ozone generator for 1250 litre spa and have it installed too. Have been quoted $160-$225 for a new generator when you can get the exact same one online direct from manufacturer for $12 plus $40 courier shipping. Current generator is a Beyok Ozone FQ-301. Details in attached photo. Have the anti return valve thing already. Happy to go with another brand if cheaper and better.
Also it seems the old Beyok Ozone fq-301 like mine, had a higher ozone output of 200-300 than the one they are making today.
