Genuine question (because I have a special interest in this area):
What do you expect to happen, cycling-wise, with these parameters (which is close to what they’d be when you stop ‘cutting’ your rainwater with tap)?
And, with plants in the tank, what measurements will you perform that will leave you in no doubt that cycling has taken place?
