It indeed has been awhile! I hope you're well.
I have not ozonated macadamia nut oil but I see no reason why it would not work as an ozonated oil. Any good plant extract oil with a good level of essential fatty acids can be ozonated to provide the same benefits as ozonated olive oil.
The Nature Kleen will work. You will just have to ozonate the oil a little longer than you would using an oxygen-fed machine. I suggest you get a whole different tubing set and bubbler for doing oils and save the ones that come with it for water.
When you're doing the parasite mop-up, Dr Clark recommends the use of l-cysteine as well. I feel that intake of supplemental antioxidants are important when doing any oxygen therapy, including ingestion of ozonated oils. They will counteract the oxidation of of fat and the production of arterial plaque.
