Waste water from an RO water purifier
My husband recently set up a marine fish tank and has a water purifier.
After me asking for a water butt for years he decided to get one and said he would link it up to the drainpipe for the garden and he would also put his waste water in there from the water purifer.
I've just clocked he has no intention of connecting it to the down pipe and it is just for his waste water and he wants me to use it on the garden.
There was me, thinking oh fab I'll have rain water for the garden and my plants will be so much better off for it, but now I'm thinking I'll just be using poorer quality water than that that comes from the hose.
Does anyone else use waste water from a purifier on their garden ? I need some persuading it isn't going to damage my plants. I'd much rather use rain water :-( Really annoyed.
We are on light sandy soil as well so the garden benefits from being watered, although due to being on a water meter, I try and keep this to a minimum.
Any advice gratefully received. Thank you.
