Whilst I accept that there is a long-standing use of 'dose' as a verb, I have been pondering whether you are using it correctly.
Saying 'He dosed himself with vitamins' is one thing. But I initially had doubts about saying 'vitamins were dosed to him', which would be equivalent to your saying 'anti-foaming agent was dosed into the tank'. It made me wonder whether it would be better to say that 'the tank will be dosed with an anti-foaming agent'?
In short is it the medication which gets dosed to the patient, or the patient who is dosed with the medication?
My position would have been the latter, had it not been for an entry I discovered in the OED from 1758 (the most recent available):
1758 R. Pultney in Philos. Trans. 1757 (Royal Soc.) 50 74 They knew how to dose it very exactly.
